To install the chuck on the drill shaft, a hole is made in its lower part along the shaft diameter. The fastening can be due to a threaded connection or holes with a taper and a tight fit of the chuck on the 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. The key adjusting ring is moved and tightened using a special key. When the key is turned clockwise, the drill is fixed in the chuck. An adjusting sleeve is installed in the quick-clamping sleeve, the surface of which is corrugated for easy rotation by hand. By manually rotating the sleeve clockwise, the drill is fixed in the chuck.
Keyless chucks are of two types: one-liner and two-liner. If the design provides only one sleeve, 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 from the outside).
Reasons for difficult removal of the drill
Drill types: a. Centerless spiral; b. Spiral with a center and cutters; c. Spiral with a screw center; g. First center; d. Center; e. Gimbal; g. Countersink; h. Groove; and. Cork.
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 tool jamming mechanism can occur when using a low-quality drill. So, if it is made of a soft material, then when it rotates, metal shavings can appear, 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, may 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 control element. The reason may be the failure of the spring blocking mechanism, which does not release the regulating element when the button is pressed.
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 simple. By turning 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 drill body (cartridge with one sleeve) or a 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 to lightly strike the key vertically or strike the sleeve with the palm 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 remove a jammed drill from a drill?
Such a necessary tool as a drill appeared in the house.
The drill is used for drilling various types of materials, therefore it is necessary to change drills very often.
The first holes have been drilled and the drill needs to be changed. How to pull the drill out of the drill with your own hands correctly?
Drill chuck design
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 housing, 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.
Using a vise
In cases where the drill is severely 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.
- The 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 cartridge.
- 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, care must be taken not to damage the surface.
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 rotating the gas wrench counterclockwise, the sleeve rotates relative to the drill clamped in the vice.
You can further enhance the impact 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 carried out with a gas wrench fixed on 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.
How to remove a drill with a working chuck
If everything is in order, then in theory there should be no problems with getting it. Therefore, this section is rather devoted to users who are completely ignorant of anything about a power tool, since the operation itself is elementary. But still there are a lot of people, so maybe someone will need this information as well.
In this situation, you will need a special key to unlock the key cartridge, or straight arms to relax its quick-release analogue.
In the first case, you need to insert the key into one of the grooves on the chuck and start rotating it counterclockwise. The promotion occurs due to the existing teeth on both objects.
In the second, the drill should be turned on in reverse (reverse rotation) mode. With one hand we hold the outer shell of the cartridge, and with the other we press the start button. If your machine is not equipped with a reverse, then this is not very good. This actually should not be, since only key cartridges are placed on such devices. But nevertheless, if this happened, then it is necessary to somehow fix the axis of the drill (for example, with an open-end wrench) and rotate the outer body of the cartridge counterclockwise. In general, here it would be better to remove such a cartridge and put the key one.
How to change a drill in a drill without a key
As the subtitle suggests, this is about key patrons.
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 in 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 rotation.
If these steps still don’t work, try what is described in the next section.
How to remove a drill from a drill?
Greetings to everyone in the next article! While operating this or that device, the user sometimes encounters unpleasant moments. Today I will touch on one of them. In this text, I decided to give some tips on how to remove the drill from the drill if you can’t do it. The reasons why this seemingly simple thing cannot be done can be very different. Here I described the main aspects on this topic and identified three main areas that I consider necessary to disclose:
- Replacement of a drill in a normally working chuck;
- Pulling out the drill without a key;
- Removing a drill that is stuck due to one or another existing damage.
Let’s consider each of these circumstances separately.
Removing a drill from a damaged chuck
Here we will also talk about cases where the drill itself is damaged.
Damage is usually in the form of a broken cam or damaged threads. It also happens that the drill is damaged, for example, by rolling between the cams. As a result, chips are formed, which interfere with normal rotation, as they are clogged in different slots, which prevents rotation.
So, for starters, you can try to relax your fists. This can be done again with two gas wrenches or one with a vice.
In the first case, each part of the chuck is clamped with its own key and rotation is performed to unscrew it. In the second, fixing one of the parts is no longer carried out with a key, but with a vice. Since this creates a large enough force, the release is quite easy.
In addition, in the absence of a gas wrench, you can clamp one part in a vice, and on the other, apply gentle blows with a hammer tangentially. Relaxation occurs due to the generated vibration.
If the previous methods do not help, for example, due to the fact that the thread on the cams is torn off, then you will have to resort to the next point.
First, you will need to twist the chuck from the electric drill. I have already described how to do this on this page. Then we clamp it in a vice and knock out the drill from the inside with a punch of a suitable diameter, which is threaded through the hole into which the spindle is inserted.
That’s all. These are the basic solutions you can apply when you need to pull the drill out of the drill. As you can see, everything is very simple. Of course, in special cases, different adaptations may be required, although the ones I have described are those that most DIYers have. Hope my advice will help you. I wish you that you will not have similar problems again. Until next time!
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.
Drill device. What you need to know about the tool?
The drill bit jammed in the chuck of a drill or screwdriver happened 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, 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 vibration 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 will lead to its jamming. Occasionally 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 quite severe 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 for this from the current in order to avoid accidentally starting the drill.
Mounting device. Non-combat cartridge
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 unit, 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 hex.
Convenience and ease of use have made the cam mechanism popular. However, it is not without its drawbacks. One of them is the difficulty in 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 as 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.
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 is provided by this type of chuck, is quite enough for most jobs, however, in comparison with the classic version of 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 gets 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 a screwdriver? The scheme is absolutely identical. The chucks 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 the fasteners are not provided for drills with a large diameter, and the speed of a screwdriver is usually 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 way to remove a jammed tool is by tapping the cams.. To do this, the free end of the drill is fixed in a vice, a wooden strip is applied to the chuck, through which tapping is carried out. This vibration can loosen the grip and release the tool. This method will be 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 oil or vegetable oil. If neither one nor the other is at hand, you can make a “bath” of your drill and gasoline. Keep the cartridge in liquid for at least an hour. By combining methods, the jammed drill can be removed even faster.
How to replace the chuck. Update the drill
Most often, the cartridge is the first to become unusable 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 bolt with a left-hand thread. 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, tighten it even more, rip off the cap and eventually carry it to the service.
By unscrewing the bolt, you can also 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 from 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.
