How to insert a bit into a drill

Drill

Can I drill?

It is possible to use a tool instead of a drill only if such a possibility is indicated in the technical data sheet of the device.

However, soft materials such as drywall can be drilled even with a low-power screwdriver.

To do this, instead of a bit, you need to insert a drill into the chuck to work with gypsum board.

To remove the drill or other attachments, you need to unscrew the chuck by hand or wrench. You also need to move the sleeve to the appropriate position, usually this mode shows the drill icon. The attachment is placed at right angles to the marked surface. It is not recommended to deviate. this will complicate the drill stroke, increase the diameter of the hole being made.

To drill a concrete or brick wall, tiles, you will need a tool with a high rotation speed (from 1200 rpm) and high torque. Impact screwdrivers do the job more efficiently and faster.

Important! A screwdriver differs from a drill and a hammer drill in power, and it should not be used to drill a large number of holes. You need to take breaks during work so that the tool does not fail due to overheating.

Tool set

Usually, such a tool is sold in special cases, where each part has its own place.

The drill itself consists of a main tool and a removable battery, which is recharged from the household electrical network.

A special charger is used for charging, which is included in the kit.

Operating tips

To work effectively with a screwdriver, you need to correctly set the torque. When working with soft materials (drywall), switch it to the minimum mode, when drilling or screwing fasteners into hard surfaces. to the maximum. Before changing the mode, you need to turn off the device and wait until the engine stops completely.

To prevent dust from flying into your eyes when drilling into the ceiling, you can put a plastic or paper cup on the drill. All dirt will collect in it, and it will be easier to control the progress of work.

Important! Household screwdriver models are not designed for intensive use. If the tool is used for a long time, it can overheat and cause the engine to burn out. If the case becomes too warm, you must immediately turn off the device and wait until it cools down.

Bits. nozzles

The screwdriver comes with several types of bits with different shapes of the working edge.

Bits with a straight edge are designed to work with fasteners that have one slot (slot). A suitable bit is selected depending on its length and depth.

Similarly, the shape of the cross-shaped bit is selected. here the width of the slot and the dimensions of the fastener head itself are taken into account. For reliable operation, the edge of the bit must fit tightly into the slots, otherwise there is a possibility of “licking” the edges of the slots.

To attach the bit to the cartridge, a special attachment with a magnetized holder is used, which prevents the structure from disintegrating and reliably holds the bit in a variety of positions.

To fix the bit with the bat, you need to unscrew the movable part of the chuck.

Insert the nozzle and screw in the chuck as far as it will go.

There are also very convenient double-sided bits that can be fixed in a chuck without a nozzle.

Battery Charging Procedure

It is necessary to insert the battery into the device, observing the polarity (the corresponding signs “” and “-” are affixed on the battery and on the device), i.e. plus is combined with plus, and minus. with minus.

A glowing red diode on the device panel indicates that the charging process is in progress. This procedure lasts from 3 to 5 hours.

The rechargeable battery is protected against overcharging, so it can be left in the device for longer, but not more than 24 hours.

During recharging, the battery and the device itself may heat up, which is not an indicator of a malfunction.

Instrument care instructions

The screwdriver needs minimal maintenance. In order for the tool to work properly, you need to adhere to the recommendations specified by the manufacturer, do not use it for tasks that are not indicated in the data sheet, do not overload too often. Periodically, the inside of the chuck and rotating parts should be lubricated with machine oil.

Store the tool in a dry place away from heat, moisture and sunlight. After each use, wipe the case with a clean, dry cloth to remove construction dust from it. If drops of mortar have fallen on the screwdriver, you can clean it with a well-wrung out soapy cloth.

If you follow the operating rules, do not use the tool for tasks that exceed its capabilities, you can significantly simplify the repair and construction work. In order for the screwdriver to work for a long time and not fail at the wrong time, you need to take care of it in a timely manner, monitor the condition of the parts and recharge it before use.

An irreplaceable power tool in everyday life with a self-explanatory name, the screwdriver is actively used in construction work. The most common procedure with such a device is to replace the drill. Sometimes it seems that this process is very difficult and practically impossible. However, in fact, replacing a drill in a screwdriver will not be difficult, the main thing is to follow the instructions step by step and pay attention to the details.

How to insert an accessory into a screwdriver

The cordless drill / screwdriver is a must-have tool for any home craftsman. Its versatility allows you to easily perform work both on tightening and unscrewing various types of fasteners (screws, self-tapping screws, screws), as well as drilling holes.

Let’s look at how a drill-driver works and understand the attachments and accessories.

Chuck rotation direction

The design of the drill. screwdriver has a push-type switch with which you can change the direction of rotation of the chuck for twisting or unscrewing the fasteners.

There is a direction mark on either side of the tool next to this switch. By pressing the switch, you can reverse.

How to insert Drill bit into drill machine

It must be remembered that it is possible to change the direction of rotation only when the electric motor is completely stopped.

In the middle position, the switch blocks the operation of the tool. This lock is used while changing bits or drills.

The drill chuck can be replaced if necessary. It must be borne in mind that it is fixed with a screw with a left-hand thread and therefore it must be unscrewed clockwise.

This screw can be accessed through the front of the chuck.

The tool kit also includes a set of drills of different diameters. They are all designed to work in relatively soft materials.

The drills are clamped in the chuck in the same way as the bit with a bit. (See photo above)

To care for the instrument, it is enough to wipe its body with a damp cloth and then dry it, do not use household chemicals and solvents.

Freezing of the battery is not allowed.

What to do if the drill gets stuck

Drill stuck

Removing the drill from the chuck is usually not a problem. For example, in a key holder, it is enough to turn the key counterclockwise. In the keyless chuck, everything is just as simple. For this, the clutch turns counterclockwise. According to this principle, drills are pulled out of other types of chucks. But what if the drill is firmly seated in the chuck? This problem most often occurs with keyless chucks. It will take a lot of effort to remove the drill.

For example, the drill can be held in your left hand and casually hit the bottom of the chuck with the inside of your hand. Usually, after such actions, the drill is easily removed.

If the chuck is metal, you can also lightly tap the chuck with a hammer. It is necessary to tap until the tail appears from the cartridge. If this does not work out, then you can use the gas key.

If no manipulations help you, you will have to remove the cartridge from the drill / punch and disassemble it.

There are other times when the drill gets stuck in the wall. In this case, the drill is rotated in the chuck. To remove it, you will need to open the chuck and remove the drill from the wall.

So, as we have considered with you all the possible situations that may arise when working with a hammer drill and a drill when changing a drill.

Often there may be difficulties and problems in working with a hammer drill or drill. Mainly, the problem may be the inability to work correctly with the drills. First, let’s look at some of the differences between cartridges and drills.

Varieties

Varieties of cartridges

Drills are divided into used according to:

  • wood,
  • metal,
  • glass,
  • plastic,
  • tiles,
  • concrete.

Drill varieties

Drills can be:

  • Spiral. They are versatile and can be used for drilling a wide variety of materials.
  • Crowned. If depth adjustment is needed, this drill is used, which can make the hole large.
  • Perovs. These drills make holes in wooden products.
  • Stepped. They are used for drilling in ondulin, iron and metal tiles.
  • Milling.
  • Roughed and so on.

The drills also differ in their tip. They are specially made for impact and conventional drills, and are shaped like a cylinder.

As for the cartridges themselves, there are also differences. For example, some are used for a hammer drill and others for a conventional drill or hammer drill. In each case, you can fix the drill in different ways.

You can find cartridges into which it is possible to insert drills for both a hammer drill and a drill. But for security reasons, it is better not to do this. The principles of operation of a hammer drill and a drill are very different from each other.

Jaw chuck for drill

Cartridges, in turn, can also be of two types:

  • quick-clamping,
  • key.

The key chuck requires a special key to install the drill. The chuck is clamped with a key that is inserted into its hole and rotates clockwise. So, the drill is securely fastened. As for the quick-release, it is divided into two types: one-sleeve and two-sleeve.

The technique of replacing the cartridge is presented in the video:

The double-sleeve chuck has two couplings, one of them is clamped, the other coupling is twisted with the other hand. If we talk about single-sleeve cartridges, then the cartridge is clamped with one hand. The replacement of drills in such a chuck is much faster than the key. But as for the fixation of the drill, it is much weaker with this option.

Chuck device

The drill is always mounted vertically, otherwise there is a risk of breaking not only the drill, but the tool itself.

So, how to insert a drill into a hammer drill or drill correctly?

How to insert a drill

Drill lubricant

For this process to go smoothly, it is important to follow some sequential steps:

  • Make sure the drill is unplugged before installing the drill into the drill.
  • Then insert the drill into the chuck. To do this, you must first make sure that the drill used is intended for a specific tool.
  • To reduce wear on the chuck on the hammer drill, you can lubricate the drill with a special lubricant. It can be applied to the hole of the cartridge.
  • Next, secure the drill.
  • After installing the drill into the chuck, it is important to make sure that it does not wobble.

During the drilling process, do not touch the rotating elements of the drill or hammer drill. As you can see, the installation of the drill is not a particular problem.

It all depends on the cartridge you are using. But what if after work it is impossible to remove the drill from the chuck?

Drilling metal

Next: Drilling process

Mounting of drills, reamers, countersinks and countersinks on drilling machines, depending on the shape of the shank, is carried out in three ways: directly in the tapered hole of the spindle, in adapter tapered bushings, in a drill chuck.

Tool holder directly in the tapered bore of the spindle. Tapered shanks of drills, reamers, countersinks, etc., as well as tapered holes in the spindles of drilling and other machines are made according to the Morse system. Morse cones are numbered 0, 1, 2, 3, 4, 5, 6; each number corresponds to a specific cone size. The numbers of the adapter sleeves are selected according to the size of the cones of the cutting tools. In the tapered bore of the spindle, the taper shank is held in place by the frictional force between the tapered surfaces. The ponytail foot fits into the spindle groove and protects the shank from turning.

Fastening of the tool through adapter tapered bushings is carried out in cases where the taper of the tool shank is less than the taper of the spindle bore. Transitional tapered bushings (Fig. 220, b) are short and long. In fig. 220, c shows fastening of the tool using an adapter sleeve. A bushing with a drill is inserted into the hole of the machine spindle.

Innovators Yu. M. Orlov and Yu. V. Kozlovsky proposed and manufactured transition sleeves from spring wire with a diameter of 2.5 mm (Fig. 220, d). The wire is wound on a special mandrel, then the outer surface is ground on a circular grinding machine. From the upper side, a plug is inserted into the sleeve, which serves to punch out the tool. The spring bushing is lighter and cheaper to manufacture than standard bushings. It does not rotate, which protects against scuffing. The sleeve is used on drilling and turning machines.

Removal of the tool from the tapered hole of the machine spindle is carried out using a wedge (Fig. 2, a) through the slot. In fig. 2, b shows a safe wedge with a spring used without a hammer.

The wedge for removing drills or adapter sleeves from the spindle of the drilling machine of innovator B. M. Gusev consists of a massive hollow handle, inside which there is a movable firing pin with a wedge, spring-loaded.

To remove the drill or adapter sleeve from the spindle, the wedge of the device is inserted into the groove of the spindle, and the handle is sharply moved. In this case, the spring is compressed and the bottom of the handle hits the wedge striker.

The force required to compress the spring is negligible, as it is only intended to move the handle back to its original position.

Fastening drills in chucks. Drills with a cylindrical shank are mounted in drill chucks, the main types of which are shown below.

In fig. 3 shows a three-jaw drill chuck in which the tools are held in place with a key. Inside the chuck body (Fig. 3), there are three cams obliquely with a thread connecting them to the nut. The holder rotates with a special key inserted into the hole in the cartridge body. When the cage rotates clockwise, the nut also rotates. The clamping jaws, going down, gradually converge and clamp the cylindrical shank of the drill or other tool. When the cage is rotated in the opposite direction, the cams, rising upward, diverge and release the clamped tool.

In fig. 4, a, b shows a three-jaw self-centering chuck for fixing drills with a diameter of 2 to 12 mm with a tapered shank. A bushing with an external thread is screwed onto the threaded part of the shank, onto which the chuck body having an internal cone is screwed. When the body is turned clockwise, there are three cams pressed against it by springs. converge and clamp the drill.

Three-jaw chuck with tilting jaws provides more accurate and stable drill clamping. The cage is firmly mounted on a nut, on the inner cone of which there is a thread, and on the end there are tapered teeth. In the grooves of the chuck body there are three obliquely disposed cams; on their outer sides, a thread is also cut, which is connected to the thread of the nut. When the cage is turned with a special wrench that has tapered teeth at the end and is inserted into the hole, the cams converge or diverge, clamping or releasing the drill.

Plants produce three standard sizes of chucks with inclined cams: PS-6, PS-9, PS-15 (the number in the brand indicates the largest diameter of the drill clamped by the chuck).

The collet is used to clamp small diameter drills with a cylindrical shank in drilling machines. Collet chucks provide reliable, precise tool clamping. The body of the collet chuck has a shank for fixing the machine spindle in the cone and a threaded part, onto which a nut 6 is screwed, having flats for a wrench on the side. The collet is mounted on the cone. When screwing the nut onto the threaded part of the collet, it compresses and fixes the drill shank.

Quick change cartridges. When machining parts in which it is necessary to sequentially drill, countersink, reamer, thread, etc., you have to frequently change the cutting tool, which takes a lot of time. To reduce the time for changing tools, quick-change chucks are used. Known quick-change cartridges with leading balls and leader. In fig. 226, 6 shows a quick-change chuck with leading balls used for light work. It is structurally simple and allows tool change without stopping the machine spindle. The chuck body is fixed with a shank in the machine spindle. In the cylindrical bore of the body there is a replaceable sleeve with a tool seat. The rotary movement from the cartridge body to the sleeve is transmitted by two balls located in the transverse seats of the body. To replace the sleeve with the cutting tool, the rotation of the cage is suspended by taking it by the corrugated surface, and the cage is raised up to the stop in the spring ring embedded in the groove of the body. Downward movement of the cage is limited by the second spring ring.

Correct installation of the drill in the drill chuck

Before figuring out how to properly install the drill into the hammer drill, it is advisable to figure out how to insert the drill into the drill. The chuck is the element of its design, in which the drill shank is fixed. Most models of modern drills are equipped with cam-type chucks, consisting of:

  • cylindrical bodies;
  • rings or sleeves that rotate around the outer surface of the body;
  • cams installed in the inside of the housing.

Jaw chuck design

When the sleeve is rotated clockwise, the cams simultaneously approach each other, thereby reliably clamping the shank of the drill to be installed. Accordingly, the question of how to pull the drill out of the drill is not difficult to solve: it is enough to start rotating the sleeve counterclockwise. This will cause the jaws to open, making it easy to remove the drill from the drill. It should be borne in mind that before installing the drill, the jaws should be unclenched with a margin, in which case the tool can be easily inserted.

The convenience of using cam-type chucks lies not only in the efficiency and high reliability of the tool installation, but also in the fact that drills of almost any diameter can be inserted into them. When using such chucks, there is usually no difficulty in changing the drill bit in the drill. Correctly inserted tools are held securely in these chucks and allow a precise hole to be drilled.

If you begin to notice slipping of the teeth when tightening the chuck, replace the worn-out wrench with a new one.

Jaw chucks are used in both industrial and household drilling tools. Clamping devices for household drills are available for two ranges of drill diameters: from 0.8 to 10 and from 1.5 to 13 mm.

The design of jaw chucks can provide for two different ways of clamping the tool: key and keyless.

In the first case, the sleeve is driven by a special key, on the tapered working part of which there are teeth. The key, to activate the clamping mechanism, must be inserted into the holes on the side of the chuck body and rotated. There may even be three such holes in some models. Accordingly, in order to loosen or clamp the cams, the key must be inserted into each of them and start rotating counterclockwise or along it.

After loosening the cams with a key, it is necessary to turn counterclockwise and the chuck itself, which will increase the distance between the cams to the required value. The inserted tool is fixed in the reverse order: first, the chuck itself is clamped (when it is turned clockwise), and then the sockets are clamped with a key.

Removing and installing drills is much easier and faster when using the keyless chuck. In it, the sleeve is actuated by manually rotating it. To limit the retraction force of the cams, they are often equipped with locking elements.

Before inserting the drill, first make sure the drill is in working order and disconnect the power supply. Only then can you start installing the drill.

How to correctly insert and pull the drill into a hammer drill, screwdriver and drill

The popularity of the question of how to insert a drill into a hammer drill or an electric drill is explained quite simply: such devices are actively used both in industrial and domestic conditions.

The cartridges are different, as well as the attachments fixed in them.

An incorrectly installed drill can lead to a number of problem situations:

  • inability to work with a hammer drill or drill;
  • obtaining uneven holes with a broken inner surface;
  • the drill will fly out, which can lead to serious injury.

Despite the fact that it is not so difficult to insert a drill into a hammer drill or drill, this issue should be approached responsibly.

Installing the working tool on the hammer drill

As mentioned above, the hammer drill must be checked for operability before installing the drill. To carry out such a check, the working mode of the hammer drill is set to drilling without knocking. If, after pressing the start button of the device, you hear and feel that its engine is running smoothly and without jolts, then the hammer drill can be used for its intended purpose, having previously inserted a drill or drill into it.

To mount a drill with a cylindrical shank in the hammer drill, use an adapter with a jaw-type chuck

Before inserting the drill into the hammer drill, it is necessary to treat the shank of the working tool with a special grease that will protect it from corrosion. The very procedure for installing the drill into the hammer drill is as follows.

  • The rotary hammer is installed with its back on the floor or other hard surface.
  • The movable part of the clamping device is pulled back.
  • The tool is inserted into the punch until it stops. In this case, the drill or drill, which must be inserted into the hammer drill, must be held vertically. If you neglect this requirement, you may be faced with the fact that the tool will fly out or even break, and this can also lead to failure of the hammer drill itself.

Press until it clicks, then pull the drill, if it is not removed, everything is fine

Considering the fact that the chucks on modern rock drills differ in a fairly simple principle of operation, there are usually no questions about how to get the drill out of the hammer drill.

Having removed the used tool from the punch in order to replace it with another, it is advisable to immediately clean its shank from grease and construction dust. In this case, the shank of the drill that you are going to insert must also be cleaned and pre-lubricated. A tool replaced in this way will not harm the clamping mechanism of the hammer drill and will last much longer.

Lubrication extends the life of both the drill itself and the rock drill

Using a perforator, you can not only get a drilled structural element, but also perform processing using a special chisel. You can also install a mixer as a working element of such a device.

DIYers often also have questions about how to insert a drill into a screwdriver or how to change a chuck on a hammer drill. The solution to the first question is quite simple, since the design of the screwdriver uses cartridges of the same design as on drills and hammer drills. But the question of how to correctly replace a cartridge on a perforator should be approached competently: it is not easy to perform such a procedure without having certain knowledge and skills.

A Few Tips for Using a Drilling Tool

In order not to face the fact that a flying tool or concrete chips will harm your health, drilling work must be performed in compliance with all safety measures. Safety goggles, gloves, ear plugs or ear muffs should be used to ensure this safety. Naturally, all work must be performed in special clothing, in which there should be no hanging elements that can wind around the drill.

To prevent overheating of the electric tool used for drilling, it is necessary to regularly rest it. It is very important to insert the drill correctly (this must be done up to the stop of the tool).

Two ways to clamp the thin drill into the chuck if the jaws are slightly short of the shank

If the drill gets stuck in the wall during drilling, it should be removed without removing the tool from its surface. To do this, the drill must be removed from the perforator and inserted into another, with which it is necessary to begin to destroy the wall around the drill stuck in it.

If the drill is not removed from the drill or hammer drill, then it must be clamped in a vice, and then with a hammer, using a wooden spacer, knock on the cams of the clamping mechanism. Oil can help in this matter, a few drops of which are poured into a key type cartridge.

Subtleties of operation

Electric drills began to appear at the end of the 19th century almost immediately after the invention of electric motors. The main task of the introducing tool with a percussion mechanism was drilling various holes in materials using electricity and rotating drills at high speed.

Already from the description it is clear: in order to use such a tool, you need to follow certain safety rules.

  • Before starting work, it is imperative to inspect: a drill, so that there are no open electronic (live) parts; the wire going to the network so that it is not damaged; a plug so that it is solid and working; the outlet so that it is serviceable and tightly seated in the wall. In this case, the plug must be firmly inserted into the outlet and there must be no sparks.
  • Insert the drill into the drill as tightly as possible.
  • Select the required mode: drilling (twisting the drill at high speed) or drilling (drilling using a hammer mechanism).
  • Select the maximum torsion speed of the drill.
  • After making a hole of the required diameter and length, press the off button, and then remove the plug from the socket so as not to accidentally start the tool when not required.

It is worth noting that there are functional drills that recognize the diameter of the drill, have stops for fixing the required drilling depth, have handles for greater fixation of the tool in the hand, and automatically change the drilling speed. Such functional drills require additional settings so that the automation does not fail at the most inopportune moment.

The drills are selected in accordance with the requirements for the work being carried out. But it must be remembered that they are different, and some drills do not fit a particular drill.

Here the main role is played by the tool holder, which is:

  • key;
  • quick-clamping.

The first option assumes that the user has a special key that can be used to loosen the cartridge. To do this, you need to use the hole on the drill and turn the key counterclockwise or turn it clockwise, and thus clamp it. Often this key is attached to the drill, which reduces the likelihood of losing it and allows you to remove the key from the mount and use it at any time.

The second option is something different, because the quick-release can be:

  • single-seat;
  • double-clutch.

If you use a single sleeve chuck, you only need one hand to clamp, and the second option is a little more complicated: you have to clamp one sleeve, and with the other hand, turn the other sleeve. Both options save time, but the retention is much worse than using a key chuck.

Keyless drill removal

Key chucks have a definite advantage. the fixation of the drill is very powerful, but there is also a drawback. it is necessary to have a key at hand. If the key is not in place, it is quite easy to make up for this deficiency. You will need to find an object that can fix the cartridge on one side. This can be a nail, Phillips screwdriver, screw, hexagon of a suitable size. To the second half, you need to make an effort with your hands and try to untwist it. this way it is possible to pull out the drill without a key. But if you can’t handle it with your hands, you can use a vice or a large gas wrench of a suitable size.

Troubleshooting

In situations where the drill is used only for narrowly targeted purposes and from time to time, users tend to send it for repair at the first problems that arise. However, in most cases, it is enough to be able to bypass the non-standard situations that have arisen. To fix minor problems, you need to know how to change the drill, whether it can be done without a key and how to act in the event that it is stuck.

How to insert a drill into a drill?

This operation is simple and quick, however some rules must be followed. Step-by-step instructions will keep you safe while setting the drill into the drill.

  • Disconnect the instrument from the mains.
  • Then choose a suitable drill, taking into account the nature of the work, the material in which the hole will be made and the compatibility of the drill with the drill.
  • Place the drill into the chuck with the shank inward.
  • Then the cartridge should be fixed, taking into account its appearance. If it is key, then fix it with a special key with teeth, if it is quick-clamping, then fix it with your hands.
  • After the drill is locked, make sure that it does not wobble in the chuck and that there is no play.
  • Then you can get to work.

It should be noted that the choice of drills depends on your electric drill. There are various models with a variety of technical equipment and capabilities. Some drills cannot, for example, be used for metal work. Others. allow the installation of drills with a diameter of 0.8 to 10 mm or 1.5 to 13 mm. It is not recommended to buy cheap drills made of low-quality metal, it is better to overpay, but make sure that the tool works properly and for a long time.

How to remove a drill bit from a drill?

If you need to change a drill that has become unusable, or due to a change in the nature of the work, you need to put another one, then the process is even simpler than when setting the drill.

In this case, there is also a step-by-step instruction.

  • Switch off and de-energize the electric drill.
  • Depending on the chuck, use a wrench or turn the sleeve by hand, turning it counterclockwise, thereby loosening the chuck. Avoid touching the drill bit, as it may remain hot for a while after use.
  • After removing the previous drill from the chuck, change it to another and continue working or put the tool away for storage.

If you cannot turn the cartridge the first time, do not rush to the workshops, most often it is enough just to put in more effort.

In any living space, sooner or later, a situation arises when something needs to be redone: hang a picture, screw on shelves or make wiring. But most of the concrete and brick walls cannot be pierced with a nail and a screw cannot be screwed into them. Therefore, you have to resort to using an electric drill. This is a convenient device that allows you to make a hole in the wall of the required diameter thanks to a variety of drills: for concrete, metal, glass, plastic, tiles or wood. But for the successful use of an electric drill, you should know the basic rules for using this tool.

Drill replacement

To carry out this procedure, you first need to get the old drill according to the scheme described above, and then put a new one. Electric drills with keyless chucks often have problems due to the fact that the drill is firmly seated and it is not possible to unscrew the coupling. In this case, you can use a piece of cloth that will give more grip on the clutch and try to unscrew it. If this method does not help, then you need to firmly fix the drill with your hand and hit the chuck tangentially in the direction of unwinding with the palm of your other hand, continuing to fix the tool.

The main functions of the tool

The main purpose of an electric drill is to drill holes in materials. It was for this that Wilhelm Fein invented it in 1895.

Inside the plastic case are the components:

  • electric motor;
  • starting switch;
  • reducer;
  • reverse;
  • retainer;
  • capacitor;
  • impact mechanism.

A chuck for nozzles is attached to the shaft (spindle) of the drill using a thread and a fixing screw.

The fixed drill rotates both to the right and to the left. For this, a reverse switch is placed on the body. In this mode, it is only allowed to remove the drill from the hole or unscrew the screws and screws. Turn on for a short time at reduced speed.

Grinding and polishing

For grinding, use a nozzle for circles with Velcro, where abrasive circles of different grain sizes are attached. Cup or disc polish metal, wood. Use a fan nozzle in hard-to-reach places.

The file attachment is a pin that is attached at one end to the chuck. On the other, it is soldered in the form of a cone, bullet or ball. They are called cones. The holes are bored and ground with a nozzle. For rough grinding, deburring, use rasp nozzles.

The drill becomes an electric grinder with special attachments. The sharpening angle is adjustable, you can sharpen anything: drills, chisels, disc blades.

Correctly sharpened drills provide drilling quality, less likely to jam, save the tool.

Polishing attachments: soft felt, special for cars, polishing leather ends and others. To work with rotation in any direction, choose a speed of 1000 revolutions.

Drill: unexpected uses

An electric drill is bought for drilling. Then they discover great new application ideas.

  • Cut steel cable, copper and aluminum cable with a sector nozzle.
  • Remove dust by connecting a dust extraction attachment to the vacuum cleaner.
  • Cut threads in blind holes without fear of breaking the tap at minimum torque.
  • Calibrate PP-R pipes with a calibrator.
  • Pump and pump out liquids with a pump nozzle.
  • Pinch a bird. Soft punching fingers of the attachment do not damage the skin.
  • Cream honey with a stainless steel mixer-like attachment.

How to change a drill in a drill without a key

As is clear from the subtitle, here we are talking about key cartridges.

The most common method is to use a Phillips screwdriver or a nail of a suitable diameter, which is inserted into any of the available recesses on the chuck, thereby securing the first half of it. You can try to twist the other half by hand. Usually this way it turns out to be quite easy to unwind.

However, if it does not work out this way, then you can use a gas wrench or a vice instead of a hand. Using them, you will be able to create the necessary effort, which is most likely enough to carry out the cranking.

If these steps still don’t work, try what is described in the next section.

How to insert the drill into the drill correctly and how to remove it?

Often there may be difficulties and problems in working with a hammer drill or drill. Mainly, the problem may be the inability to work correctly with the drills. First, let’s look at some of the differences between cartridges and drills.

What to do if the drill gets stuck

Drill stuck

Removing the drill from the chuck is usually not a problem. For example, in a key holder, it is enough to turn the key counterclockwise. In the keyless chuck, everything is just as simple. For this, the clutch turns counterclockwise. According to this principle, drills are pulled out of other types of chucks. But what if the drill is firmly seated in the chuck? This problem most often occurs with keyless chucks. It will take a lot of effort to remove the drill.

For example, the drill can be held in your left hand and casually hit the bottom of the chuck with the inside of your hand. Usually, after such actions, the drill is easily removed.

If the chuck is metal, you can also lightly tap the chuck with a hammer. It is necessary to tap until the tail appears from the cartridge. If this does not work out, then you can use the gas key.

If no manipulations help you, you will have to remove the cartridge from the drill / punch and disassemble it.

There are other times when the drill gets stuck in the wall. In this case, the drill is rotated in the chuck. To remove it, you will need to open the chuck and remove the drill from the wall.

So, as we have considered with you all the possible situations that may arise when working with a hammer drill and a drill when changing a drill.

Varieties

Varieties of cartridges

Drills are divided into used according to:

  • wood,
  • metal,
  • glass,
  • plastic,
  • tiles,
  • concrete.

Drill varieties

Drills can be:

insert, drill
  • Spiral. They are versatile and can be used for drilling a wide variety of materials.
  • Crowned. If depth adjustment is needed, this drill is used, which can make the hole large.
  • Perovs. These drills make holes in wooden products.
  • Stepped. They are used for drilling in ondulin, iron and metal tiles.
  • Milling.
  • Roughed and so on.

The drills also differ in their tip. They are specially made for impact and conventional drills, and are shaped like a cylinder.

As for the cartridges themselves, there are also differences. For example, some are used for a hammer drill and others for a conventional drill or hammer drill. In each case, you can fix the drill in different ways.

You can find cartridges into which it is possible to insert drills for both a hammer drill and a drill. But for security reasons, it is better not to do this. The principles of operation of a hammer drill and a drill are very different from each other.

Jaw chuck for drill

Cartridges, in turn, can also be of two types:

  • quick-clamping,
  • key.

The key chuck requires a special key to install the drill. The chuck is clamped with a key that is inserted into its hole and rotates clockwise. So, the drill is securely fastened. As for the quick-release, it is divided into two types: one-sleeve and two-sleeve.

The technique of replacing the cartridge is presented in the video:

The double-sleeve chuck has two couplings, one of them is clamped, the other coupling is twisted with the other hand. If we talk about single-sleeve cartridges, then the cartridge is clamped with one hand. The replacement of drills in such a chuck is much faster than the key. But as for the fixation of the drill, it is much weaker with this option.

Chuck device

The drill is always mounted vertically, otherwise there is a risk of breaking not only the drill, but the tool itself.

So, how to insert a drill into a hammer drill or drill correctly?

How to insert the drill into the drill correctly

Not only the quality of work, but also the safety of the person holding the tool directly depends on how correctly the drill is inserted into the drill or perforator. After all, a nozzle that has flown out may well cause injury, and quite serious. Therefore, this moment should be taken with full responsibility. Any drilling tool in inept hands is always an object of increased danger. Therefore, when working with a drill or hammer drill, you need to do everything in full accordance with the manufacturer’s recommendations. Ignoring them can lead to not the most pleasant consequences.

How to insert a drill into a drill. features of different models

At first glance, there is nothing particularly complicated here. This, of course, is true, but with one caveat. There is nothing difficult in such a task for an experienced craftsman who has already worked with more than one model of a drill and perfectly understands their specifics. Meanwhile, many newbies make mistakes here.

At the same time, it should be noted that drills of various manufacturers are currently on the market. from cheap Chinese ones to world-famous brands. Bosch (Bosch), Makita (Makita) and so on. They differ from each other not only in technical characteristics. There are also differences in the design of some units. In this case, we are most interested in the cartridge. After all, it is into it that the drill is inserted. Most models today use cam-type chucks. over, they are divided into:

  • key (gear-crown);
  • quick-clamping.

At the same time, they have basically the same general principle. The cartridge consists of a cone-shaped body along which the sleeve moves (adjusting ring). The latter is just responsible for the approach and distance of the cams that fix the drill. The algorithm of actions here is very simple. Rotating the ring clockwise, you bring the cams closer to each other, in the opposite direction, on the contrary, move them apart. In the first case, the drill shank is fixed, in the second it is released.

If the principle of action is the same, then the mechanisms of its implementation are different. In particular, key girth gear designs require a special key that comes with the drill. It has a rather specific look and it makes no sense to paint the moment.

Using a key inserted into a special hole on the chuck, you can rotate the ring, which has a corrugated surface, in the desired direction. This design provides a more reliable retention of the drill shank compared to keyless chucks. However, many craftsmen dislike such drills. After all, here you need to constantly use the key. If you need to change the attachments frequently, this wastes valuable time. In addition, the key should always be at hand. most often it hangs on a cord, on a special ring.

Keyless chucks are simpler. Here you can rotate the sleeve for convergence-spreading of the cams by hand. Of course, this negatively affects the reliability of fixing the drill, but this option is quite acceptable for a household tool. Some manufacturers put additional locking elements on their keyless chucks. They allow you to limit the tightening force. That is, it is a kind of fuse. These elements simply will not allow the cartridge to break. with excessive force, they will simply block the movement.

Well, now let’s move on to considering the main question. how to correctly insert the drill into the drill. It is easy to guess that the procedure in this case directly depends on the type of cartridge installed on the tool. In particular, in quick-clamping structures, first of all, grip the sleeve with your hand and turn it counterclockwise. This will spread the jaws to the desired distance and make room for the shank. Next, insert the drill, and do the above steps in reverse order. You need to rotate the sleeve already in the clockwise direction.

Often the power of the tool is used for this operation. In this case, you just need to hold the sleeve with your hand and press the start button. In this case, the reverse switch must first be set to the required position. After all, to separate the cams, the shaft must rotate in one direction, for mixing. in the other. As noted above, many models have locking elements. That is, you will definitely not break the tool. However, do not forget that the drill must be well held in your hands. Otherwise, the tool may well break out.

In order to install the drill into the ring gear chuck, we need a wrench. By rotating the sleeve with it (rotating counterclockwise), you will first spread the cams. Next, insert the drill and, holding it with your hand, do everything in the reverse order. That is, again, with the help of a clockwise wrench, we bring the cams together, thereby clamping the drill shank. In fact, there is nothing complicated here either. It just takes a little longer to change the drill.

And in conclusion, I would like to give some general recommendations on this issue. Particular attention must be paid to the reliability of the drill fixation. Therefore, do not forget to check this point every time. The control here is very simple. You just need to slightly wiggle the drill with your hand. If it is securely fixed, it should not wobble in the chuck. If you notice a problem, try tightening the cams. In addition, the shank must be fully immersed in the chuck. Experienced craftsmen are not advised to increase the length of the drill, deliberately ignoring this requirement. The risk that the nozzle will simply fly out of the cartridge, and even cause injury, will be quite high. Therefore, do not expose yourself to unnecessary danger.

Another important point. When fixing the drill in the chuck, make sure that it is level. Any distortion after clamping the jaws is not permissible here. Such a tool is already becoming dangerous. As a result, you will damage the workpiece, or break the nozzle, not to mention the possibility of injury, because the broken part of the drill with a certain degree of probability can hit the eye. Therefore, when installing a drill, you do not need to neglect elementary safety rules.
