Why does a screwdriver not clamp the bat and what to do
Using a manual drill, some are faced with the problem of extracting bats from the cartridge. With intensive work, the fists can press to the change with great effort and even jam, so that it is difficult to crank the cartridge even with the help of a special key. The reverse task, when the screwdriver does not clamp the bat, occurs less often and is characteristic of faulty fastening. About what to do if the bit is not fixed properly, then.
The reason for the incorrect operation of the mounting mechanism, when the screwdriver does not pinch the bit, there may be wear of one or more of its elements.
On the outside of the fists there are teeth that enter the clutch with a swivel gear and when twisting move upward along the conical guide, clamping the shank of the drill. When grinding the teeth on the fists or on the gear, the pressing force becomes insufficient for reliable holding the bits.
There is an option when the fists, although they do not completely converge, but to a certain diameter can provide the necessary pressing value. It is possible a temporary solution. Bits wrap the wire on the shank (the best material. Copper), increasing the diameter and thus tightly tightened the impromptu design.
These are extreme measures that allow you to realize the ability of the tool only in case of emergency.

Network screwdriver Diold has a key cartridge. In order to remove such a cartridge, we dump to the maximum of the fist, to open the bottom, and with a screwdriver, unscrew the clamping screw along the left carvings. To fix the cartridge from the rotation of the spindle, fix it with either the key from the cartridge or, wrapping a tool with a rag or installing plastic nails on the sponges, we pinch in a vice. Having turned the screw, we easily remove the old cartridge.
If you can’t unscrew the screw, remove the case cover and fix the spindle inside.
Do not forget to turn off the screwdriver from the network! When replacing the cartridge, you do not need to turn on the tool.
The first mandatory stage! Displaying the fixing screw
The first, mandatory, stage when removing the cartridge from most household screwdrivers is to remove the fixing screw located from the endel end between the fists. This fastener is designed to protect the fast.And.Packed assembly from independent “leading” when working with loading in reverse mode (counterclockwise).
For example, when unscrewing old fasteners, when it is necessary to increase the torque. At the same time, the cartridge can remain motionless, fixed in the processed surface, and the spindle will perform rotations “to the left” (counterclockwise) and independently get out of the fastener of the screwdriver.
To prevent such situations, manufacturers use a control screw with the “left” thread. It is it that needs to be removed first, performing the following actions:
- Dilute the fists so that the tip of the screwdriver flows freely between them.
- To unscrew the screw, performing rotation to the right side, since it has a “left” thread.
Attention! Grooves on the heads of the screws can be of different sizes and shapes (straight or cross.Shaped). Therefore, you must have screwdrivers with different tips.
Swiming a fast.Packed cartridge from a spindle of a screwdriver After the fixing screw with the “left thread” was unscrewed from the end of the spindle, you can remove the fast.And.Packed cartridge from the screwdriver.
Due to the fact that the gap between the coupling and the case is several millimeters, it is not possible to fix the spindle with a vise or pipe key. Therefore, there are several other ways to remove the cartridge.
Holding the cartridge with his hand
The easiest way is to hold the cartridge with your hand. To do this, you need to perform the following actions:
- Put on a special glove on the hand that will hold the cartridge.
- Install the torque regulator on the maximum indicator or put the screwdriver into drilling mode.
- Make sure that a fixing screw is unsettled from the end of the spindle.
- Take the fists of the cartridge to the minimum gap.
- Holding the cartridge with one hand protected by a glove, start the rotation of the screwdriver in the reverse direction (counterclockwise). While the fists diverge, the electric motor will gain momentum, and at the time of their complete opening, a peculiar blow will be obtained, which must move the threaded connection. Now it will not be difficult to swing the cartridge.
Attention! This is an unsafe method! It is forbidden to use it when confirming at least one point:
- Lack of a special glove.
- The power of the screwdriver exceeds 500 watts.
- Lack of good physical training (adolescents, women, people of advanced age).
If this method is not suitable for the above prohibiting reasons or turned out to be unsuccessful, then it is necessary to apply the following.
Using a Mr
This method is quite simple and safe, therefore it is a priority. It is necessary to perform actions in the following sequence:
- Make sure that a fixing screw is unsettled from the end of the spindle.
- Fix in fists a Mr. The best hexagonal key.
- Set the torque regulator for maximum value or transfer it to the drilling mode.
- Switch the spindle rotation direction into the reverse regime (counterclockwise).
- Run the engine and give it the opportunity to gain maximum speed.
- Bet up rotating, fixed between fists, Mr. For example, locksmithing, gymnastic gyra.
- At the time of the impact of the fixed Mr.
Attention! The cartridge is unscrewed very quickly, within less than one second. Therefore, it is necessary to provide that it falls from a minimum height, that is, the emphasis on which the stress will take place with a Mr-shaped tool should be as close as possible to the floor.
The second version of this method is also possible:
- After the screw is unscrewed and the robbed key (three-, four-, five-, hexagonally) between the fists, hold the screwdriver in one hand, and with the help of the other we strike with a hammer (kiyanka) on the shoulder of a protruding tool so that the rotation occurs counterclockwise.
- “Tearing”, thus, the cartridge from the place can be unscrewed by the hand.
This drop.Up subspecies is especially effective in cases where there is no voltage on the network (network screwdriver), the battery or power tool is discharged is discharged.

Bit holders are connected to the tool with the help of:
- Cone Morse. This type of fastening refers to a very reliable. The cartridge is put on the shaft and snaps.
- Threads. In this case, it is wound on the shaft.
You can see at the screwdriver itself Test, which indicates the method used. On the surface of the inscription 1-6 B10, talks about the presence of a conical connection. 1-6 is the diameter of the shank in mm, 10-cone. To remove it, you will need a hexagonal key for 10.
When threaded, the cartridge is marked 1.0-11 m121.25. Two initial numbers indicate The diameter of the shank drill. The numbers that are after the letter mean the value of the thread. On the devices supplied from abroad, the marks are indicated in inches, therefore they may vary from the above.
Screwdriver: how to disassemble its cartridge
To get inside, you should remove the plug. If the case is plastic, it is easily done: it is praised by a sharp object.
It is knocked out of a metal case with a hammer. To do this, they hit the base of the clamping sleeve so as not to damage it. To get to the base, a fairly large bolt is put between the fists. Then the fists are shifted so that the bolt takes the perpendicular position relative to the base, but at the same time it was not tightly clamped and had the opportunity to move both the top and down. Then on the head of the bolt protruding over the cartridge, they beat a hammer.
After that, the cartridge can simply be disassembled enough. After the repair or prevention, the node is collected back, paying special attention to the position of the cams.
