How to remove a drill from a drill
Using a vise
In cases where the drill is heavily jammed, the use of a vise can be recommended. To extract it, you need to carry out the following operations:
Another way to remove the drill from the drill is to use a vise.

- A jammed drill is firmly clamped in a vice, so that the drill itself is parallel to the table.
- Lightly tap with a small hammer over the entire surface of the chuck.
- Then light but sharp blows are made with a hammer on the sleeve vertically along a tangent to its surface.
- If the movement has begun, then the blows should be continued until the drill shank appears from the butt end.
- If there is no movement, then the blows should be intensified. In this case, it is necessary to ensure that the surface is not damaged.
The efficiency of the method can be increased by using a gas wrench. It can be used only in the case of a metal cartridge. it is simply not possible to clamp the plastic cartridge securely. The sleeve is firmly clamped with a gas wrench. By turning the gas wrench counterclockwise, the sleeve rotates relative to the drill fixed in the vice.
The effect can be further enhanced by using two gas keys. In this case, the drill shaft or a fixed sleeve (in the case of a cartridge with two sleeves) is fixed with the second gas wrench. Counterclockwise rotation is performed with a gas wrench attached to the cartridge adjusting sleeve; the second key must be stationary. Thus, the rotation of the sleeve relative to the drill and drill must be ensured at the same time.
Drill chuck design
In all types of drills, the drill is installed in a special chuck. With this tool, the drill is attached to a rotating shaft, and the rotary motion required for drilling is transmitted to it. In this type of drill, such as a hammer drill, it also provides a translational (impact) movement of the drill. Almost all drills use cam-type mechanisms.
The chuck consists of a hollow cylinder-shaped body along which an adjusting sleeve or ring moves. Cams with a conical cut are installed inside the body, which move along guides that provide translational movement of the cams when the adjusting element rotates. Due to the taper, the cams evenly converge relative to each other when moving upward or evenly diverge when moving downward.

Easy drill removal
In order to remove the drill from the chuck, it is necessary to turn the adjusting sleeve.
In the usual mode, the issue of extraction is very easy to solve. By rotating the adjusting sleeve or wrench counterclockwise, the cams are opened, after which the drill is removed. In the presence of a locking mechanism, rotation begins with pressing the locking button. When the regulating element rotates, the body of the drill (cartridge with one sleeve) or the fixed sleeve (cartridge with two sleeves) is fixed by hand.
If it is not possible to turn the sleeve or the key immediately, then it is necessary to try to increase the load or create an enhanced initial load impulse. The first attempt is to set the movement with a sharp jerk of the right hand, while ensuring the fixation of the drill with the left hand. The next attempt is a light blow with the hand on the key vertically or a blow with the palm of the hand on the sleeve in a tangential direction to the surface of the sleeve. If the manual method of influence did not help to pull out the drill, then you should resort to using a mallet or a light hammer (preferably a rubber one). Strikes are made with this tool on a key or sleeve. The force of the blow increases as needed. To increase the force effect, it is advisable to introduce a lubricant (oil) into the area of the cams before impacts.

How To Change a Drill Bit
In the process of working with a drill, sometimes difficulties arise when replacing a drill associated with removing a previously used drill from the chuck. This problem can be of varying degrees of complexity, depending on the cause of the occurrence. The simplest and most common reason is the application of excessive force when clamping the drill, in the absence of restrictive mechanisms in the chuck design. This phenomenon most often occurs when using a percussion method of impact to tighten the drill in the final stage, for example, the use of a mallet. Drill jamming can also occur if it is forcefully tightened when it is incorrectly placed in the space between the jaws. This is typical when using a small diameter drill.
A more complex mechanism of tool jamming can occur when using a low-quality drill. So, if it is made of a soft material, then when it rotates, metal shavings can occur, removed from the surface, which clogs the gap between the cams and the drill, as well as between the cams. This can make it difficult to open the jaws when trying to loosen the drill. Difficulties in removal can arise if the drill has sunk too deep into the chuck during operation. The task becomes more difficult if the drill, in addition to such jamming, also breaks at the level of the upper end of the chuck.
The breakdown of the drill in the drill chuck can be caused by a violation of the drilling mode.
The reason for the destruction, in addition to the use of low-quality material, can be a violation of the drilling mode: an unexpected tilt of the drill, excessive vertical load, an attempt to drill a heavy-duty material, etc.
Finally, the reason that the drill cannot be removed is a jamming of the cartridge itself. Several possible reasons should be highlighted. The first reason, not related to the failure of the cartridge, is explained by the ingress of foreign particles that impede movement into the area of the threaded connection of the regulating element and the body. Such particles can be dirt, metal dust or small chips, etc. In this case, it is not possible to ensure the rotation of the adjusting sleeve or key.
The reason for the fact that you cannot get the drill can be the failure of the chuck. This can be caused by both the presence of a factory defect and temporary wear of the cams or the regulating element. The reason may be the failure of the spring locking mechanism, which does not release the regulating element when the button is pressed.
Mounting a drill in a drill
To install the chuck on the drill shaft, a hole is made in its lower part along the shaft diameter. Fastening can be due to a threaded connection or holes with a taper and a tight fit of the chuck on a shaft having a reverse taper.
The drill is inserted in the center into the space between the cams. When the cams converge (clockwise rotation of the adjusting element), the drill is fixed in the chuck, and when the cams diverge, on the contrary, it is released. To ensure a secure fit, it is necessary to apply significant forces when rotating the adjusting element.
According to the method of fixing the drill, the chucks are divided into ordinary (key) and quick-clamping. In the key, the adjusting ring is moved and tightened using a special key. When the key is turned clockwise, the drill is secured in the chuck. An adjusting sleeve is installed in the quick-clamping sleeve, the surface of which is corrugated for ease of rotation by hand. By manually rotating the sleeve clockwise, the drill is fixed in the chuck.
Keyless chucks come in two types: one-liner and two-liner. If only one sleeve is provided in the design, then it rotates relative to the drill body, which must be fixed motionless during installation. When using two sleeves, one of them is movable, adjusting, and the other is fixed. The adjustment sleeve is rotated relative to the second sleeve, which must be fixed when installing the drill. In the design of the chuck, to limit the tightening force, additional elements can be used in the form of a ratchet (located inside) or a locking spring mechanism with a button (the button goes into a special socket outside).
Removing the chuck due to a jammed drill
If the drill is jammed due to the fault of the chuck, then it must be removed from the drill shaft. There are two types of fastening of the element on the drill shaft: threaded and tapered. When threaded, the element is fixed in a vice, and the drill rotates counterclockwise relative to it. If there is a locking screw, it can be unscrewed with a screwdriver or a gas wrench.
With a conical fastening, the chuck is installed on the shaft “in an interference fit”.
It can be removed by lightly tapping a hammer on the bottom end.
After removing it from the drill shaft, you can make one last attempt to pull out the drill. To do this, all internal elements (cams), together with the drill, are knocked out of the body by light blows on the upper ends of the cams.
The tool you need to pull out the drill:
- a hammer;
- gas key;
- rubber hammer.
A jammed drill inside the drill can be difficult to remove. However, a little effort and knowledge of cartridge design will help to cope with this problem.
Removing the drill with a working chuck
If the fixing element of the tool is in good condition, the drill can be removed quickly without problems. The whole process can be described as follows:
- To unclamp the chuck, a special wrench is required, which often comes with the tool.
- The key fits into any groove in the chuck and rotates counterclockwise.
- The movement of the chuck occurs due to the clutch of teeth located directly on the chuck and the tool used.

In addition, there are other mechanisms for fixing the cutting tool, which are also easy to use.
How to get a drill from a damaged chuck?
Most of the problems with removing the drill occur when the chuck has been damaged. often than not, damage is represented by a broken cam and cut threads. In addition, there is a situation when the drill itself is damaged, which begins to scroll in the cam. As a result of some deformations of the fixing element, chips can occur, which further contributes to the wear of the structure.

The work of extracting the drill in this case may be:
- In the relaxation of the cams, for which two gas keys can be used. A vise can be used instead of a gas wrench.
- If there is no gas wrench, then the device can be clamped in a vice and lightly hit with a hammer. In this case, impact marks will appear on the surface of the fixing element. In order to reduce the degree of surface deformation, you can use a hammer, the working part of which is made of hard rubber.

How to remove a drill from a drill: tips and tricks
A drill is one of the most common tools that can be used for a wide variety of work. The cutting tool in the case of a drill is a drill. It is attached to the tool head and can be quickly changed if necessary. When using almost all construction tools, a situation may arise when serious problems arise with the removal of the replacement part. A fairly common question is how to remove the drill from the drill. Let’s consider the features of such work in more detail.
What to do in the absence of a key
When using a drill that has a key chuck, difficulties may arise due to the lack of a special key. An ordinary Phillips screwdriver can be used to wring out and clamp the chuck. You can also use a nail of a suitable diameter.
When using a screwdriver, you have to unwind the chuck by hand. If this does not work, then a gas wrench can be used. With the gas key, the required force can be created. However, do not forget that the gas wrench, under strong impact, can deform the surface of the cartridge.
The drill is inserted into the key hole provided in the chuck, and the screwdriver rests against the gear ring.
Note! It is not recommended to unscrew with hammer blows, as this kind of action can deform the cartridge. It is best to purchase a wrench that matches your specific drill model.
The design of a modern drill is quite simple, if necessary, tool changes can be made as soon as possible. If the cartridge is damaged and the necessary key is missing, you have to resort to folk methods, for which it is enough to have a regular set of tools.
How to change a drill bit in a drill. proven methods!
What repairs would cost without a good drill and drill set! However, even the most reliable tool can jam during operation. Don’t rush to panic! We will teach you how to change a drill in a drill and correctly diagnose other breakdowns.

The chuck is the fastener in which the drill is fixed. The fasteners themselves are screwed onto the tool spindle. Most often, drills are equipped with a jaw chuck. This design is a hollow cylinder with metal “fingers” inside. When turning the adjusting ring, which is located outside the assembly, the “fingers” converge or diverge along the inner cone-shaped surface. In such a “fist” you can clamp both a drill with a cylindrical shank and a hexagonal.
Convenience and ease of use have made the cam mechanism popular. However, it is not without its drawbacks. One of them is the difficulty of working with small drills. A short piece can simply fall inward. You can still fix it by putting the drill in a horizontal position, but you cannot press on it hard during work. If another drill has been inserted into the drill, you can remove it by turning the adjusting ring in the appropriate direction. It is not always possible to do this manually, for this there is a special key that acts like a lever, increasing the effort. By the way, tightening the drill without a key is also not recommended. the larger the drill diameter, the more reliable the fastening should be.
When buying fasteners, make sure that it is rubberized. this way you will less injure your hands when fastening the tool.
Keyless fasteners, the second most popular, can be operated without a key. It is enough to insert the drill and turn the lever, often it can be done with one hand. The fixation of the drill, which this type of chuck provides, is quite enough for most jobs, however, compared to the classic version of the fastening, it is inferior in reliability, and it is more expensive. The main advantage of the quick-release fastening is the speed of changing the drill and the safety of the process, since such a chuck is devoid of teeth that can injure hands. The absence of a specialized key is also a significant advantage! Seasoned builders know how easily it is lost, so very often you can see the key tied with tape or electrical tape to the wire.
True, this does not add convenience, but there is at least some confidence that the key will not have to be looked for throughout the construction site. How to change a drill in an electric screwdriver? The scheme is absolutely identical. the cartridges for most drills are similar to fasteners on screwdrivers. Of course, the latter tool cannot be a full-fledged replacement for a high-quality drill, if only because fasteners are not provided for drills with a large diameter, and the speed of an electric screwdriver is, as a rule, less.
How to change a drill in a drill. we do it ourselves!
The drill can not always be removed from the chuck in the usual way. as a result of a strong load or improper fixation, it can jam the chuck. How to get the drill out of the drill without damaging the fasteners and tools? First of all, try to cool the cartridge well. Sometimes this is already enough for the cams to release the drill a little, and you can pull it out.
The most proven method for removing a jammed tool is to tap the cams. For this, the free end of the drill is fixed in a vice, a wooden bar is applied to the chuck, through which tapping is carried out. This vibration can cause the chuck to loosen its grip and free the tool. This method is useful both for owners of classic fasteners and for owners of quick-release fasteners. Extraction is sometimes possible after lubricating the drill with machine oil or the popular WD-40 grease.
The latter method is better, because the sprayer will quickly reach the desired points of contact between the drill and the chuck. In any case, after lubrication, you will need to wait a little for the substance to penetrate deeper. Sometimes, in especially difficult cases, the problem is solved only after dipping the entire cartridge in machine or vegetable oil. If neither one nor the other is at hand, you can make a “bath” of your drill and gasoline. It is necessary to keep the cartridge in the liquid for at least an hour. Combining methods will remove a jammed drill even faster.
Drill device. what you need to know about the tool?
A drill jammed in a drill chuck or electric screwdriver has occurred at least once with every tool owner. To understand why this can happen, you need to understand how the drill works. This tool converts electrical energy into mechanical energy, which is possible thanks to an electric motor that rotates the shaft. Through the gearbox and gears, the rotation is transmitted to the fasteners, in which the drill is fixed.
Now let’s look at the operation of an electric drill from the back side, provided that the drill was not secured correctly or not firmly enough. Vibrations that occur during operation will lead to deviations in the direction of drilling, resulting in a curved hole. Vibrations from vibrations will be transmitted to the gears and the gearbox, they will hook the shaft and the engine itself. this does not immediately threaten to breakdown, however, a decrease in the service life of the tool is guaranteed! Often, carelessness in securing the drill leads to its jamming. Sometimes jamming occurs as a result of the drill slipping off the drilling point. to avoid this, use a spring center punch to make indentations in the surface for the drill.
In addition to jamming, a loosely fixed drill can jump out of the fastener, and this is already fraught with severe enough injuries for the person working with the tool and others, given the speed of revolutions of modern devices. Therefore, never fasten the drill in a hurry, always disconnect the drill from the current in order to avoid accidentally starting the drill.
How to replace the chuck. update the drill
Most often, it is the cartridge that comes into disrepair first in the drill. Dismantling it at home is not easy, but possible! The fasteners are screwed onto the spindle itself, but in addition it is also secured with a left-hand threaded bolt. In order to get it, you need to completely unclench the cartridge. it is inside. The whole difficulty of unscrewing it lies in the fact that many do not know about the left-hand thread, and trying to unscrew it, twist it even more, tear off the hat and eventually bring it to the service.
By unscrewing the bolt, you can unscrew the cartridge itself, however, and this is not so easy to do. In some models, there are notches for a wrench at the base of the thread. in this case, you can fix the spindle and unscrew the fasteners using a lot of effort. The real difficulty arises when there are no wrench cuts. You will have to remove the housing cover to fix the spindle inside the drill. Difficult but doable.
Removing a cartridge is one thing. Finding a new one is completely different. In addition to the methods of clamping the drill, which are described above, different chucks also have different threads! The surest way not to confuse anything is to take an old cartridge with you and demonstrate it to the seller, or how to choose the right one according to the layout. When you have coped with this task, all that remains for you is to screw the chuck onto the spindle and tighten the bolt, which in our case is twisted counterclockwise.
