electric screwdriver how to work with nozzles

Grinding and polishing nozzles on the drill and an electric screwdriver types and purpose

Among hand tools the hammer is in the lead, while the first place in the arsenal of electric tools belongs to the drill. Electric drill not only drills holes in metal and wooden structures, but also performs work on polishing and grinding different surfaces. To do this, you need to buy a nozzle on the drill for polishing and grinding. Tasks such as removing minor scratches on a car body or sanding the surface of wooden structures and workpieces can be performed quickly and easily with it.

When it is necessary to perform polishing, grinding or scraping surfaces, then to solve these problems will help special attachments that are fixed in the chuck of power tools, like a drill or an electric screwdriver. Used in a variety of industries such as mechanical engineering, construction, auto repair, carpentry, jewelry shop, industry, etc.п. To polish the car, you will not find a better tool than a drill with a special attachment to it.

This is interesting! Polishing nozzles are available for angle grinder, but using an angle grinder as a polishing tool is not always rational. This is due to the large number of revolutions that the power tool produces. When polishing with an angle grinder you can burn the top layer of paint coating.

Polishing nozzle on the drill can be used for processing a variety of materials. metal, ceramics, concrete surfaces, marble, granite, glass, wood, plastic, etc.п. If the car body is covered with small scratches of paint coating, you can remove them with a sanding nozzle fixed in the chuck of the power tool.

Types of bits for an electric screwdriver for each application

The shape of the bit depends on what it is for. According to this feature are distinguished heads :

• professional;
• Spring-loaded and magnetic;
• with the “fork” design;
• for drywall;
• with an anti-vandal slot;
• for nuts and bolts.

Experts advise to buy the bits as a set. Sold individually, they cost more.

Many fasteners are screwed in with these heads. They can drive and tighten about 400 screws and still leave the bit in good condition. Professional bits are made of high quality metal. Products are protected by a special coating.

Such a kit usually contains a torx bit for an impact model of an electric screwdriver. It differs in appearance. The torsion product has a very narrow section between the slot and the shank. It has a special flexible insert in the form of a spring. which works in a twisting manner. Thanks to this design, the torsion bit is used when screwing into materials with a non-uniform structure or high density. Self-drilling fasteners are used. Such head can be used to drive a self-drilling screw through metal, including the whole head.

Nozzles, which are designed for drywall sheets, have a limiter. It prevents damage to the material during installation. Drywall is a fragile material, so screw in screws without strong pressure.

Bits, which can be used for tightening and unscrewing nuts and screws, have non-standard shape. The working part of these heads has a hole. These bits are made in different sizes. If screws and nuts with large flats are to be driven, then an electric screwdriver with high power is needed.

Screwdrivers that are equipped with an anti-vandal slot also have another name, the snake eye. The shape of such tip is adapted for a fork spanner.

Bits with a fork-type design are a type of anti-vandal slot. In appearance, it looks like a flat head, only in the middle it has a slot. These parts are made of quality steel. so they stand out for their strength and durability.

Magnetic-tipped bits with a spring clip are designed for work in hard-to-reach places and on the ceiling. Holds bit in adapter. The magnetic tip firmly fixes it in the grooves of the screw, prevents the nozzle from slipping, the screw can be screwed deep. Spring-loaded socket lets you work on fasteners in hard-toreach places and at different angles.

Replacing the cutting tool

The “tail” of an electric screwdriver drill bit is fastened in the chuck. It comes in several sizes, as do the bits. An electric screwdriver can cause damage to your workflow and health if the cutting tool is not installed correctly. For example, because of the “wrong” drill bit you may get holes of different sizes with a damaged surface. A sharp element in “flying out” of the chuck will cause serious injury.

Most modern screwdrivers have cam chucks. They consist of a cylindrical body and a sleeve and cams. When the shell rotates clockwise, the jaws simultaneously press the drill bit against the drill bit.

The process of changing it is not complicated, but has a number of individual peculiarities. The whole process can be described as follows:

• You have to find the right bit for the drill bit;
• then take the cutting tool and put it in the center of the chuck (between the opened “cams”);
• after that, it should be secured by turning the cartridge case clockwise (with the key-type cartridge, the key is placed in the recess);
• turn the sleeve until the bit is fixed.

It is not difficult to change the drill bit, but first you must pull out the previous one. There are the following variants of development of the situation:

• Standard drill bit extraction (chuck is not damaged);
• Pulling out the drill in the absence of a wrench;
• Pull out the jammed part of the cutter.

If the electric screwdriver works properly, you shouldn’t have any problems replacing its working tool. the operation is elementary. To do this, you need to take the wrench that is designed to loosen the chuck, and insert it into the recess. Turning counterclockwise. Unscrewing is carried out by special teeth that are available on the objects. There is also another way of removing the drill bit. To do this, switch the electric screwdriver to reverse rotation, hold the outer chuck body and press the “start” button. In this way, the drill is easily released.

If we do not have a special key, we can use a Phillips screwdriver or a nail to remove the drill bit. Insert it into the recess in the drill bit chuck and fix half of it in place. Twist the opposite side of the chuck by hand. However, if this kind of unscrewing does not bring results, then take a gas wrench or a vise. these tools will help to strengthen the rotation of the chuck. If the previous options for pulling out the drill have failed, then you should resort to “heavy artillery”. In some cases, external damage to the drill bit makes it difficult to retrieve. In this situation, it is necessary to loosen the “cams” with a gas wrench and a vise. Fully clamp the chuck with wrenches and make rotation (unscrewing).

In this process, the simultaneous use of both a wrench and a vice is welcome. You can also take a hammer and use it to hit the cartridge lightly. the vibration from the blows promotes relaxation.

A radical option in the most hopeless situation is to twist the chuck with an electric screwdriver. To do this, it is necessary to squeeze it in a vise and forcefully knock out the cutting tool from the inside with a punch. Naturally, after such a procedure, the electric screwdriver should be taken to repair. To summarize, it is worth noting that the procedure for inserting a drill into an electric screwdriver is quite simple and it can cope even those who have never done it. The main thing in this process is to follow the recommendations.

On how to insert a drill bit into an electric screwdriver, watch the following video.

An indispensable tool in everyday life, the electric screwdriver is actively used in construction work. The most common procedure with such a device is to replace the drill bit. Sometimes it seems that this process is very complicated and almost impossible. However, actually replacing the drill bit in an electric screwdriver is not very difficult, the main thing is to follow the instructions step by step and pay attention to the details.

What to do if the chuck in the electric screwdriver is jammed?

If the bit is jammed in the chuck of an electric screwdriver Bosch, Texas, Practice and others., if the chuck is jammed in the chuck of an electric screwdriver, it (after lubrication) is effectively resolved by using two adjustable wrenches. You first clamp the base of the chuck and then gently rotate the upper part of the chuck with the other.

Electric screwdriver as a drill is used in repair work quite often, unless they are associated with drilling holes in concrete and brick materials. Purpose of an electric screwdriver. Tightening and loosening screws, self-tapping screws If the drilling function is not activated, the electric screwdriver works like a drill.

Electric screwdriver button principle and construction

Battery voltage is supplied to the motor through the button. Button is not only used as a contact-actuating device.

The button has the following tasks:

• Closing the “plus” and “minus” contacts of the wires, by which power is supplied to the motor
• Reversing. reversing the polarity of the contacts of the wires going to the motor. This allows the motor shaft to rotate in different directions
• Speed adjustment depending on how hard the starter button is pressed

The purpose of the button is to provide a smooth voltage supply to the tool motor when the trigger is pulled.

Polishing attachment

As in the previous case we need a screw, washers and a nut, only instead of emery cloth we will use felt. Having marked a piece of felt, let’s cut circles of the same radius out of it.

Holes are made in the center of the workpieces, they are threaded onto a screw, and then clamped with a nut. The finished device is inserted into a drill chuck. One felt will not polish the part, so by turning on the drill, the nozzle is rubbed with Goya paste. After that you can get down to work.

An old and rusty wrench was used for the purity of the experiment. As you can see on the photo, after a short polishing the treated area was effectively cleaned in a short period of time.

With such a polishing attachment you can work with both flat and shaped parts, but it will not cope even with small pits.

Leather disc

As in the fixture described above, leather can be fastened instead of felt, resulting in a fixture for dressing wood cutters.

We use a file

You can use a circular file as an accessory by removing its handle and pressing the shank into the chuck. The small-diameter file is best secured to the base.

With such a device it is convenient to grind holes and semicircular hollows.

Epilogue Whether you use a purchased drill bit or make one yourself, it can prove invaluable for many jobs.

The drill’s main purpose in woodworking is to drill holes. However, this tool is much more functional than many people think. To expand its functionality use special attachments for woodworking, which, in fact, is devoted to this article.

Next we will consider what are the attachments to the drill for woodworking, and for what purposes they are used.

Dissecting shears

Another useful tool is the notching scissors. They are also used for cutting sheet material from metal. This tool is more maneuverable, unlike rotating discs. Although it takes longer to cut with it, it gives you a more precise cut. The cutting shears leave behind cuttings. The edges of the workpieces have a straight edge, so there is less risk of cutting your hands while working. Installation of the notching shears takes less time than with the circular shears, because they do not require an additional point of fixation, with a special tie-rod leading to the handle of the electric screwdriver.

Turbo shears

The Turbo shears are another useful attachment for your electric screwdriver. They work on the same principle as the classical lever scissors for metal, but are connected to a screwdriver, which greatly speeds up the work process. They can be used not only to cut sheet metal, but also plastics and other hard materials. The peculiarity of this nozzle for an electric screwdriver is the absence of vibration, and the main thing is that it does not damage other surfaces, which it touches with the back of the claw. For example, these scissors can be used to cut sheet metal roofing material, one side of which has already been fastened to the roof. In this case you can cut the protruding part without damaging the surface of the finished roof. If you use disc types, they will leave scratches on the paint of the roof, so turbo shears are more versatile.

Using the Turbo scissors it is possible to cut not only sheet metal, but also wire and thin rods. Such a tool comes in handy when working with steel mesh, because it allows you to quickly cope with its cells when trimming.

Sector Scissors

These are no less popular nozzles for an electric screwdriver, which allow you to perform trimming of plastic pipes used for installation of water supply systems. With their help you can cut a thick and powerful power cable, inside of which there is a reinforced part in addition to the conductive veins. Useful for installers. Of course it should be taken into account that such scissors can not cope with metal pipe, but they can handle plastic quite well. The secateurs of these shears move in a circle. It is crescent-shaped, so it cuts into the material efficiently. This tool differs from one another in the diameter of material it can grip. Thanks to the gear system, the tool creates a minimum load on the electric screwdriver motor. Although visually the sector scissors clamp slowly, but in fact they are much more convenient and faster to use than using a hacksaw for metal. Such a tool is cheaper than a specialized assembly tool.

90-degree angle attachment

Angular nozzles for an electric screwdriver appeared quite a long time ago and are already available in the set of many craftsmen who are engaged in furniture assembly or professional repairs. This accessory is an adapter made at an angle of 90 degrees, with which a screw can be driven into surfaces in hard-to-reach places. It comes in handy when the clearance is too big to fit an electric screwdriver because of its length. This accessory is quick and easy to attach and remove and makes screwing very easy and eliminates the need for a short-handled manual screwdriver.

Ribbon accessories for fast assembly

Ribbon nozzles for electric screwdrivers speed up installation work. Unlike most accessories, they do not extend the capabilities of an electric screwdriver, but increase its effectiveness. The accessory is clamped in the tool holder and allows the tool to work with screws in their cartridges. No need for all fasteners to be picked up and manually applied to the bit in order to perform the installation. The screw strip is automatically guided and positioned under the bit. This increases the working speed by several times, which can be useful if you need to tighten thousands of screws. Such equipment is indispensable for the installation of roofing materials.

Riveting tool

even a riveting gun can be replaced by an electric screwdriver thanks to a special accessory. It enables rivets to be tightened by pressing a button on the tool. Much more convenient than constantly squeezing the levers of a hand tool. The advantages of using such a nozzle for an electric screwdriver are not only speed and reduced physical exertion, but also quality riveting. The fact is that they are pulled with equal force without jerks, so their tail comes off correctly. As a result, the rivet looks neat and holds securely.

Water pump

There are nozzles for an electric screwdriver that make it useful in a wide variety of household applications. One of the brightest such representatives is a water pump. This is a compact device that allows you to turn an electric screwdriver into a water pump. Its speed depends on the power of the tool itself and the rpm it is capable of producing. The pump is a small, compact, washer-shaped housing with a shaft at the center. It is clamped in the chuck of the electric screwdriver. There are two tubes coming out of the housing that are designed to fit flexible hoses. One end of the hose is thrown into a container with water or a river and the other end is directed to the point where the water needs to be pumped. In doing so, the pump itself and the electric screwdriver must not come into contact with water, because it is destructive for the power tool.

How to properly care for your tool

Both cordless and corded models require periodic maintenance and constant care. Together with proper storage and lack of overloading, these factors will help to extend the life of the screwdriver.

Quality care is as follows:

• Do not allow water to come in contact with the tool. The product should therefore be stored in a dry place.
• It is forbidden to drop the electric screwdriver.
• Do not overload the power tool: the heat of the housing is a guide here and there. Only sharp drill bits should be used.
• Periodic lubrication of the chuck must be carried out: the regularity of this operation is indicated in the operating instructions.
• Dirt, dust, chips and other contaminants should be removed with a dry cloth (fuels and lubricants in particular). Also, you should wipe the device you are using at the end of the day. Always keep the tooling and accessories clean and tidy.
• Batteries should be stored so that there is no short circuit between their terminals. Drives must not be deformed and must not be left in direct sunlight.
• For lithium-ion batteries it is recommended to store the batteries half charged to their maximum capacity, for nickel-metal hydride batteries. fully charged, nickel-cadmium batteries. partially discharged (but only slightly).
• Nickel-cadmium storage batteries should be subjected to 3 complete charge/discharge cycles after storage (or new) before use to maintain their capacity, and nickel-metal hydride batteries should be subjected to 4-5 cycles before use.
• Manufacturers recommend storing and operating their power tools at temperatures between 1000 and 2700 degrees Fahrenheit.5 to 30 degrees.
• The battery charger of rechargeable models must be disconnected after charging the batteries to prevent overheating.
• It is recommended that the integrity of the product in use, especially the moving parts, be checked before and after use.
• When drilling, it is recommended to periodically cool the nozzle in various ways.

Following these care recommendations does not take much time, but contributes significantly to prolonging the use of the product.

Before you start using your new electric screwdriver, it is recommended that you first read the manufacturer’s instructions for use. It already specifies the design features of the model, its technical characteristics, suitable area of application, frequency of maintenance, recommendations for transportation and storage. Also be sure to include the safety rules that should be adhered to.

If the tool smells of melting plastic or insulation, smoke, uncharacteristic noise, excessive vibration appears during work, it is worth stopping its operation immediately.

When the product is under warranty service, it is better to take it to the service. Otherwise, you can try to repair it yourself.
