How to disassemble the chuck of an electric screwdriver

Despite the fact that today there are many models of screwdrivers on the market, they have one general approach to removing such an element as a chuck. We will now briefly describe it.

In order to unscrew it, you need to remove the screw that secures it to the shaft. It is located inside the chuck, the screw should be rotated clockwise. After you unscrew the screw, jerk the cartridge in the opposite direction with a jerk.

Attention! When you try to unscrew it by hand, you must put the drill at the second speed, if it is two-speed. When buying a tool, it is advisable to lubricate the screw with machine oil. In some cases, when this element does not want to give in, then you should put the tool at the first speed, hold it in your palm, and turn on the reverse to the left. The chuck should come off the thread easily.

Electric screwdriver chuck thread

Structurally, this movable element is fixed in the tool body in three ways:

  • Fastening with a Morse taper.
  • Threading.
  • Securing the set screw.

Mounting with a Morse taper has been known for a long time and is as follows. The shaft has the shape of a cone, repeating the outline of the surface inside the chuck. the same cone. By combining them in a certain way, you get a reliable connection.

Docking the shaft with the chuck using a threaded connection consists in the presence of a thread at the end of the shaft, onto which a chuck with the same thread can be freely screwed.

The fixing screw is most often used as an additional fastener. Its head has notches for a Phillips screwdriver, as well as a left-hand thread. You can see this screw by unscrewing the cams that close it.

To find out what kind of mount your instrument has, you need to carefully inspect the body of the instrument. The designation for each type of attachment is different. For example, this: 1–6 В 10 will mean that the chuck is fixed by means of a B10 Morse taper, and nozzles with a shank diameter from 1 to 6 mm can be used to it. If there is such a record: 1.0–11 M 12 x 1.25. you will know that you should use nozzles with shanks from 1 to 11 mm, the metric thread has a section of 12 x 1.5 mm. Foreign manufacturers use indicators in inches, for example, 1.0-11 ½. 20 UNF.

In this article, we examined the main problems that arise during the operation of the tool, paid attention to such a responsible unit in the design of an electric screwdriver as a chuck. Together with this, we figured out how it is attached to the structure of an electric screwdriver, gave some advice on how to repair it with our own hands, and also tried to outline in general terms ways to solve repair problems.

When trying to insert a large diameter drill, the chuck of an electric screwdriver jammed. Is it possible to restore it?

an electric screwdriver can actually jam when trying to insert a drill of the maximum permissible diameter into the chuck. An electric screwdriver of absolutely any brand can jam, regardless of its price.

How to fix or open Black and Decker Cordless Drill Jammed Chuck, Stuck Chuck in 5 Minutes

The chuck of an electric screwdriver can jam not only because a drill of the maximum permissible diameter was used. This can also happen due to unevenly clamped “cams” in which the drill or bit is fixed.

The tool can also jam due to the fact that dust, dirt, particles of metal shavings and other construction debris can get under the “cams”.

Whatever the reason for jamming the chuck of an electric screwdriver, the first thing to do is to pour a special universal grease inside the chuck, wait 10-15 minutes and then knock with a rubber hammer (carefully, without strong efforts) on the chuck and on each of the cams.

The most common breakdown of screwdrivers is a jammed chuck. If you are faced with a situation where the chuck is jammed in the Hammer electric screwdriver, first you need to deal with the type of breakdown.

The chuck does not close

Typical breakdown, especially in cases where a large diameter drill is used in the work. When unclenching the holding cams, for example, when using a drill of the maximum diameter calculated for a given model of an electric screwdriver, there are situations when the device is unclenched, but does not want to bring the clamp together. In this case, the cartridge rotates, but the work is paralyzed. Uneven clamping of the cams, in which the fixation of the drill is broken, is also a common breakdown.

Algorithm for solving the problem: grease is poured into the cartridge, for example, WD-40. Time is given for its penetration into hard-to-reach places, usually 5 minutes is enough. To speed up the process, you can warm up the cartridge with a hairdryer. Next, the cams are tapped from different sides with a rubber hammer.

Alternatively, after the lubrication procedure, you can clamp the front part of the electric screwdriver chuck in a vice, and at the same time try to clamp the upper part with an adjustable wrench.

We remind you that the chuck clamping mechanism is an integral sub-assembly that allows the use of drills of various diameters in operation. If the chuck is jammed in the Hammer electric screwdriver, we recommend contacting the service center.

Every active user of the tool has encountered a situation when the clamping mechanism of the chuck of an electric screwdriver Interskol, Makita or any other brand has jammed. This structurally simple, but functionally significant unit is subjected to severe dynamic, vibration and shock loads. Dust, metal shavings and other small mechanical fractions also penetrate into it. all these factors lead, if not to fatal breakdowns, then to periodic malfunctions of the mechanism.

Types of malfunction

Typical cases in which the chuck of an electric screwdriver Metabo, DeWALT, etc. wedges:

  • when trying to use a drill of the maximum permissible size, the cams are bred to the maximum, after which it is not possible to bring them together with the application of regular efforts;
  • it is not possible to remove the drill or bit clamped in the chuck. the jaws do not open. Often at the same time they are clamped unevenly, which worsens the fixation of the drill.

Less often, the jaws jam during their free stroke when compressed or unclenched. usually this is facilitated by particles of debris, scale, shavings, etc., caught under the shaped part of one of the cams.

Repair methods

Experts recommend, regardless of why the electric screwdriver has jammed, what to do first: in the inner cavity of the chuck, including the surface of the cams, introduce a universal grease like WD-40. After 10-15 minutes, use a rubber hammer (or an ordinary one, through a gasket) with moderate effort to tap the chuck and the cams.

If the bit is jammed in the chuck of an electric screwdriver from Bosch, Texas, Praktika, etc., then (after lubrication) the use of two adjustable wrenches effectively solves the problem. One clamp the base of the cartridge, the second gently rotate its upper part. In order to avoid damage to the surface and the knot itself, you should use soft but dense skin-type pads.

If your efforts have led nowhere, with minimal financial costs and extremely quickly the functionality of the tool will be able to restore the specialists of the workshops of the company “Udachnaya Tekhnika Servis”.

Why a bit can get stuck in an electric screwdriver

It doesn’t matter if the tool is expensive or cheap, it is not uncommon for the clamping device to jam. This happens in several cases:

  • When trying to use a drill of the largest allowable size, the chuck jaws are bred to the maximum value, after which it is often impossible to compress them normally.
  • A jammed drill or bit cannot be reached because the jaws cannot be opened. in most cases due to uneven compression.
  • Jaws can jam due to free play during compression and expansion. This is due to the trapped debris, shavings, scale, which fall under the curly parts of the cams.

Unfortunately, in such situations, it is impossible to work with an electric screwdriver, despite its serviceability. It is possible to cope with the problem on your own, in severe cases it is better to contact the service center to specialists.

How to get a jammed bit out of an electric screwdriver

The electric screwdriver is one of the most popular tools for both professional and home work. The clamping device is subjected to the most severe stresses, therefore, malfunctions may occur. The question of what to do if a bit is jammed in an electric screwdriver, how to pull out a part, remains quite relevant.

How to open a stuck electric screwdriver chuck

When the described problem occurs, a natural question arises about how to pull the drill out of the electric screwdriver when the element is jammed.

At the first stage, professionals recommend pouring a universal grease of the WD-40 type into the inside of the chuck (touching the surface of the cams). Kerosene or engine oil can also be used instead. Such solutions are recommended for use in any case of jamming.

Jamming is often due to misuse

After 10-15 minutes, the chuck and the cams must be gently tapped through the gasket with a regular or rubber mallet. Typically, the grip is loosened and the drill is released.

If this does not happen, then it is allowed to slightly warm up the cartridge with a hair dryer and try to remove the bit again. The method is suitable for owners of screwdrivers with standard and quick-release fasteners.

The jammed bit can also be removed using two adjustable wrenches. After the lubricant is added inside, rather simple actions are performed:

  • With the first key, squeeze the base of the chuck,
  • The second. gently rotate the upper part.

It is recommended to place soft gaskets between the parts so as not to damage them while they are unscrewed.

Attention! In some cases, it is quite simple to cope with jamming. it is necessary that the cartridge has cooled down well after work. As a result, the cams will open and the bit will easily come out.

There is another method by which you can cope with this problem. It is necessary for one hour to completely lower the tool into a container with machine oil (even vegetable oil is suitable) or gasoline. After this period of time, remove the product and use the described methods to get the bit out of the clamp.

If you cannot carry out the procedure yourself, then it is better to contact a specialist so as not to spoil the instrument.

There are several methods for removing the drill from the chuck.

Features of removing bits when they get jammed on screwdrivers from different manufacturers

Basically, all models of screwdrivers are quite similar, so the methods for removing the bit when it gets jammed are the same.

  • Bosch. In Bosch screwdrivers, you can get the bit by using two keys after pre-lubricating the chuck.
  • Makita. The tools of this company are distinguished by their reliability and long service life. Bit jamming occurs, as a rule, as a result of debris falling into the cartridge. In this case, it will be possible to cope with the problem if you pour lubricants into the inside of the cartridge. In the absence of a result, other methods are used.
  • Interskol. Products manufactured under this brand work well and for a long time, rarely break down. Removing a jammed bit is easy using the methods described.
  • Other manufacturers. There are many instruments of different brands on sale. Metabo, Whirlwind, DeWALT, Diold, Caliber, Hammer. There are as many ways to remove the bat in case of a problem as with other models. It is allowed to try all methods to cope with the problem.

Do I need to repair an electric screwdriver if a bit is stuck there

Regardless of which model of electric screwdriver (Makita, Bosch or Metabo), at the initial stage, you can try to get the bit yourself. The element must be pulled out very carefully so as not to damage the rest of the parts.

Before removing the bit from the electric screwdriver, it is recommended to carefully examine the tool. If necessary, it should be cleaned, and then try to remove the stuck bit. As a rule, with such a problem, the electric screwdriver remains in working order, so it does not need a complete repair.

Always inspect the tool before work.

You will have to take the tool to the workshop if you cannot remove the element yourself, and with further attempts, damage may occur.

In keyless chucks, removing and inserting drills is quite simple. In such devices, the sleeve works by manual rotation. To prevent the cams from tightening too much, they are often equipped with locking elements.

Experts recommend that before installing the selected bit in its place, make sure that the tool is working. It is imperative to turn off the product from the network.

Attention! The bit jamming in the chuck of an electric screwdriver is most often the fault of the owner. To prevent this from happening, it is recommended to service the tool in time, monitor its condition.

It is imperative to check that debris does not get stuck in the cartridge, and clean it in time. When working, you need to ensure that the product does not overheat, give it time to cool down. If necessary, additional diagnostics are carried out in order to identify possible problems in time.

In difficult situations, it is not recommended to engage in self-disassembly, otherwise you can completely ruin the tool. It is better to ask specialists to do the job.

Exploitation

When operating any electric screwdriver, you need to remember two simple rules. Let’s repeat:

  • The mode of operation of the tool should correspond to the set goal. If drilling is expected, then you need to switch to 2nd speed with the obligatory rotation of the ratchet clutch to drill mode.
  • When working with self-tapping screws / bolts / nuts, the 1st speed should be selected, and in order not to rip off the caps of the screws or bolts, the torque ring must be moved to a position that corresponds to the length / thickness of the fastener and the density of the material (selected empirically).

The cartridge, engine and battery are the three main components that require attention and care. The chuck must be regularly cleaned of dirt (our electric screwdriver does not have a chuck, but this is a general rule), the electric screwdriver must not be stored in a damp and / or unheated room, during storage, the reverse switch must be turned to the neutral (middle, stop) position (this position in our device, too). Regular battery recharging is also recommended.

At first sight

A weighty, albeit rather compact instrument is clearly intended for a strong man’s hand. Thanks to the matte plastic and rubber inserts, the electric screwdriver is securely gripped in the palm of your hand, even with cloth gloves. The manufacturer has chosen a soft color scheme, but such colors are almost never found in natural conditions, which means that an electric screwdriver can always be found with a glance in a heap of construction rubbish.

The transformer-like design, traditional for a modern instrument, provides a tolerable number of elements with pits and depressions. this is good, less dirt and dust will accumulate in these depressions.

electric screwdriver: torque

Torque is the force with which the spindle and chuck rotate. It is not difficult to measure the torque on such a simple bench (its detailed description is given here).

Screwdriver manufacturers always indicate the torque of their products. But everyone points out differently. Someone, without hesitation, writes the maximum shock moment (and with a clear overestimation of two or three times). Someone shows two options: soft and percussive. In the characteristics of the electric screwdriver under consideration, the moment is indicated as much as 25 Newton meters. Of course, this is not true. precisely, this truth has nothing to do with real exploitation. We do not use the maximum (impact) moment, since it lasts a fraction of a second. We always work only at the expense of a soft, constant moment. Which is very simple to define. Here it is:

Thus, the manufacturer lied only twice, this is far from a record. Some manufacturers act much more shamelessly, overestimating the torque by three to four times.

Manufacturer, model Torque according to the passport, Nm Measured torque, Nm Bosch Ixo

Tonfon 12V

Kölner KCD 12M

DeWALT DW907

Soyuz DShS-3314L

Makita DF331D

DEKO GCD12DU3

4.5 3.5
25 12.5
fourteen 7
twenty eighteen
24 fourteen
thirty nine
32 7

The torque obtained from our own measurements of 12.5 Nm is a very good indicator. Such power will allow without hesitation to drive a roofing screw for metal into a metal profile or wrap a long screw for wood into a thick log. It is difficult to name a scenario in which more torque may be required. Unless to tear off the caps from the screws on the neighbor’s fence. This is easily done with a torque of 20 Nm.

Characteristics

The main characteristics of the tool are presented in the following table:

electric screwdriver: battery

The complete charging dock delivers 2.5 A to its contacts at 12.8 V.

The LEDs on the top of the docking station work adequately: during charging, it lights up red, and when the battery is full, lights up green.

Everything is fine, except for one thing: battery charging takes a long time, more than three hours. But on the other hand, you can work from a full battery for about an hour almost without interruption. And it’s still a pity that the cunning seller removed the second battery from the kit.

electric screwdriver: an unscientific test that surprised

This practical test consists of screwing self-tapping screws 50 mm long and 3.5 mm in diameter into dry wood (pine). Some screwdrivers allow you to tighten more than 200 self-tapping screws in half an hour of continuous operation on a full battery charge. These are very good screwdrivers. There are also reverse examples. But the instrument in question was pretty surprising. It’s almost four hundred self-tapping screws! The hand joint ached for a long time after such testing.

How can you explain such an effectiveness of the tool? Logic dictates that such autonomy is achieved not only due to the capacity of the battery. The capacity of the battery is not space at all, the most common, 2000 mAh. Rather, we see the result of a successful selection of the engine and gearbox. Bravo!

6 reasons not to buy this electric screwdriver. bought this electric screwdriver and got upset! Immediately upon purchase, I drew on a small backlash of the cartridge, but I thought it should be so. cons 1. Yes, there is undoubtedly vibration at the second speed, but it’s not so scary. To hell with her as they say, but still there. 2. The backlight shines in the wrong direction. Where they looked and what they thought placing the backlight there. Yes, it is convenient, but only if the screw fell on the floor and highlight it to find if it is completely dark but no more. 3. Everyone says that the gearbox made of aluminum is not so, nonsense. Made of plastic 4. 2 years later, the backlash has doubled, and during idle switching on and off in second gear, a knock from the gearbox appeared. 5. And now the most unpleasant thing is the stopper that stops the chuck for a supposedly quick change of the working tool, in general, works every other time, does not stop, but scrolls. And now, in order to unscrew it, you need to do several turns. Not convenient however. 6. Rigid torque adjustment. (He screwed the screw, he did not turn until the end, and the gearbox began to snap off, rearranged it for one more division and then he screwed the screw to the very tonsils. could I look for something better!

Sadness, actually. Acquired Metabo PowerMaxx 12 serial number 1116710681 06/08/2012. It was not me who used it, but an electrician at my service station. A week ago, when releasing the tool from the chuck, he. this very cartridge has broken. Those. the sponges are jammed in the unclenched state. In this case, the outer holder of the cartridge rotates, and the jaws do not move at the same time. In general sadness.

Cool shura. Small size, comfortable, great twists. I took it for the house. I chose between df330 dummy and this one. The Powermaxx is slightly larger and smaller than the ratchet modes. BUT the battery warranty is 3 years, and it looks like it is somehow better made. In general, I am satisfied with the choice. I advise you to take.
