People! My SDS drill shank broke. Part of the shank is left in the chuck. I tried to pull the damn shank part out with light strokes, but it won’t budge. Any advice on what to do if anyone has encountered this problem. You have to drill.
remove the dust cap and the sleeve and pry it out through the ball hole

Do not tell. Not the best idea to make a powerful, essentially SDS-max format, pen with a dead plus chuck.
Is it hard to remove the dust cover and the chuck?? I’ve never done this.
Now I understand that the middle peorator should be with SDS-max, however, the problem needs to be solved.
If you don’t know how to take the chuck apart, you better take it to a service center. It is not hard to disassemble it.
- Use a screwdriver or a nail to pry it loose.п.) to squeeze the broken off shank deep down into the chuck until it stops
- Press the cartridge stopper to the opening
- turn the pedal sharply to “full throttle”. the broken shank should come out. You might have to repeat it a couple of times. it depends on what position the shank stops at before it is pressed through.
Thank you all for your help! I was very touched that so many people responded! The state of affairs is as follows. I removed the rubber on the cartridge, by the way, it is very easy to remove as it is not attached in any way. Got to the shank mounting mechanism. For those, who haven’t deal with the device, I will try to describe it in few words. The shank is inserted into the cylinder with side slots. This cylinder is in the other, smaller one, which is spring loaded and moves up and down. In the slots on the outer side there are two metal balls (about 5 mm in diameter), the second spring-loaded cylinder prevents them from falling out. So, I could get to the broken shank from above and from the side through the ball slots, as was advised by dear Lomaster from Novosibirsk. But the shank got jammed, so it was impossible to move it neither with a magnet, nor with light strokes. To flush with WD, to heat, to cool, I did not dare, because the torch is under warranty. And the cartridge is covered with grease, the origin of which I do not know. It’s either factory grease, or it came from the shanks. I took the chuck to a warrantee repair shop, they recognized it as non-warranty.е. Repair for a fee. Then they made the diagnosis. the tailcrank is flattened, to get it out you need to dismantle the cartridge thoroughly. The price for the repair was not announced, on Monday 7.06.2010 in the afternoon will tell the result. If anyone is interested in the rest of the story, I’ll let you know Monday night (Mokov time). At the end. I used a drill “Enkor”, which I bought in Leroy Merlin for 180 a piece. Drill bits 25 mm x 150 mm.
How to remove the jammed drill bit
At the time of the construction work the introduction of the torch becomes very necessary. When using it to make different holes or to dismantle old cement and stone coatings. Often there is a situation where it is impossible to remove the drilling accessories from the chuck. How to take out the drill bit without help of others and with minimum risk of tool damage? For this purpose you need to understand some peculiarities of similar problems in the tool.
If the drill bit is jammed in the chuck, you must drop a few drops of oil into the area of the junction.
Varieties and causes of jammed drills in the pen
There are 4 versions of such a problem:
- Drill bit jammed in the drill chuck or the adapter chuck for using an ordinary drill bit in the chuck;
- Drill bit (or auger) gets stuck in the drill chuck.
The first option appears because of the need to implement an ordinary drill while working with the chuck. For this purpose, there is an intermediate chuck as in an ordinary drill, it is inserted in the clamping device of the Peorator and the drilling process is carried out. At the end of the job, it is occasionally impossible to take the drill bit out freely, because it is impossible to unscrew or unclamp the chuck jaws. This fault is not difficult to solve. Usually, the drill bit jams because the chuck is not lubricated or is very dirty.
To release the clamping mechanism, you need to drop there a special penetrating liquid, for example, WD-40, it is also possible to use kerosene. After 5-10 minutes, it is necessary to accurately tap a brass hammer on a chuck, immediately using the other hand to try to loosen the drill bit. After these manipulations, the mechanism can be unscrewed. When the chuck is free, it needs to be cleaned and greased.
Drill bit jammed in the driver’s chuck in the 2nd variant. It happens for other reasons than when jamming the drill in the chuck. The drill bit or drills in a drill bit experience rotational and low impact loads, which are transmitted to their bodies only through the chuck jaws and the unchanged stop at the bottom of the chuck. The peorator has a different force transmission mechanism and different drill kinematics in its chuck. Because the peorator anticipates a rotational-impact, as it is also called impact vector of force transfer, drills and drills receive energy from a special striker, which is driven by the electric motor of the tool and strikes the shank of the inserted devices (drills, drills, bits, chisels). The insertion tool has special grooves in its own body which cause its fixation within the calculated limits and the transmission of torque. Bad tools have very soft steel, which is not heat-treated, in the course of drilling in the chuck there is a caving in of the shank, especially during long-term work.
Causes of jamming of the drill bit in the lever
During the use of the peorator you can get the auger jammed and as a result it will be very difficult to take it out of the chuck. In general, this problem can occur in 2 cases:
- Drill bit jams directly in chuck. adapter. Typically, this adapter is used during drilling mode when the need arises to use an ordinary drill.
- Drill bit jamming directly in the jaws of the power tool.
In the first case, the drill is jammed in the chuck. adapter, which is used together with the torch, because of the need to use the drilling mode without impact. This adapter has to be inserted into the power tool’s clamp before use and then the drill bit has to be placed in it.
Once all the work is completed, it can be difficult to loosen the drill from the clamping element. Therefore, in this case, to safely remove the used drill bit it is recommended to use special compounds. For example, for this purpose perfectly suits WD. 40.
Once applied, this compound, in a short period of time, manages to loosen the clamp to such an extent that the drill can be disassembled without much effort. As an alternative to WD-40 you can use kerosene. It is necessary to put it on the mechanism, then wait 10 minutes and try to dismantle the drill bit by loosening it a little and tapping the chuck.
Quite often when using a drill directly in the chuck of a power tool (without adapters) it can jam, which sometimes makes it very difficult to remove. This is generally because the auger is made of a low-quality material.
During the operation of the rotary. percussion or just percussion mode is used. As a result, all the energy is transferred to the drill from the special striker, which makes successive blows on its shank. The drill, in turn, is equipped with special grooves, which, after installation, are firmly fixed with a clamping element.
Usually low quality shanks are made of soft alloys that are not additionally heat-treated. As a result, they are not able to withstand a prolonged heavy load and become unserviceable, after which they jam.
How to release the double-joint chuck
Unlike the keyhole chuck, this type of chuck has no cog and therefore no stop. Its rings are relatively smooth. In this case the ideal solution is a removable “magazine holder” that is often included in modern drills. You will also need a hammer:
- Hold the top sleeve closest to the drill (ring) and fix it in place as securely as possible.
- Clamp the drill in a vise, clamp, in your hands or between your knees.
- Strike the “magazine” handle with force in the direction in which the upper coupling normally unwinds.

One blow is enough. the ring is dislodged and the drill bit is released quite easily. In order to make it easier to slide, it is permissible to drop some oil or grease between the chuck jaws or under the sleeve.
There are several common causes for this fault.
Among these, the two most common can be identified:
- drill bit jammed in the chuck or in the buffer element (it is used when installing a usual drill bit);
- the drill is stuck in the grip of the peorator.
In the first situation, the malfunction is due to the need for a drill, which is necessary for the functioning of the device. In order to insert it, a special element is used. a transitional chuck (the same part is used for an electric drill). It is usually placed in the chuck of the peorator and then worked on.
After completing the work, it may be difficult to remove the nozzles because they are tightly clamped by the jaws of the clamping hole. In this situation, there is a simple and quick solution because the problem arises from improper use of the clamping mechanism. Many users forget (or simply do not know) that it needs to be lubricated periodically. This is the reason why it jams.
The second situation happens because the element is stuck in the perforator itself. The electric drill bit rotates in a circle and reciprocates in some units. This is because the body of the tool transmits impulses through the bottom of the chuck and the jaws.
But the energy in the rotator is transferred in a different way and so the bits move along a different path. This tool assumes a rotary-impact and percussive motion vector of the tool. The tool receives its energy from the striker, which is set in motion when the power unit, which is connected to electricity, starts to work. This bit acts on the shanks of the tools inserted in the chuck by mechanical means (drill, drill bit, chisel, bit bit).
There are special grooves on the nozzle that are securely clamped in the clamping element. This allows them to provide torque transfer. Cheap bits are usually made of low quality materials and soft alloys that cannot be heat treated. This renders the ponytails unsuitable for further use, because they can not withstand the load. In this situation you might have to take the tool apart completely.
How to remove a jammed drill bit
Vise is often used when removing the drill If the drill gets stuck while working, you will have to pull it out yourself. However, before you do that, you need to figure out how to remove the drill from the peorator. There are a few recommendations that can help solve this problem.
A jammed part should be extracted using a vice. This tool makes the extraction much easier. There are two ways to get the drill out of the vise:
- Firmly grip the auger and wiggle it in your direction.
- Clamp the drill and hit it carefully with a small hammer. In this case, the impact must coincide with the direction of withdrawal of the tool.
Special lubricants can be used with the above extraction methods. They contribute to the release of the chuck.
Additional information! If the jam occurs due to spinning in the chuck, you have to remove it. To do this, you need to get rid of the retaining ring and the cap.
The drill should be turned in the opposite direction by 90 degrees. If this does not help, you will have to disassemble the entire torch. It is not necessary to do it by yourself. Especially if they are brand-name models from Interskol, DeWALT and Bosch.
How to save the key cam chuck
If it is only lightly corroded or if the drill bit is deformed, you will need a torque wrench, chisel or screwdriver and a 700 g hammer:
- Spray rust dissolver, grease or machine / any mineral oil into the chuck.
- Let stand for 5-20 minutes.
- Use a wrench or a socket wrench to clamp the chuck so that the drill is on your left.
- Secure the construction with a vice, a clamp, or simply with your feet.
- Place screwdriver on clamping ring, in the slot between the teeth, tilted away from you.
- Successively strike the screwdriver handle with a hammer forcing the ring to turn.
If you have two gas wrenches you can try turning both rings in different directions at the same time.
Tip Be sure to inspect the chuck: no grooves, dents or other defects left on or inside the chuck. If so, it is better to change the nozzle. Open the chuck as far as possible and undo the screw on the “bottom” to remove the bit.
What to do in such a situation if it gets stuck?
The most common cause of jamming is the drill bit caught between the rebar and the pebble in the wall. Quite common in deep plunging into a wall.
The first thing to do is to immediately stop trying to free the drill with the torch or your hands. Otherwise, there is a high probability of breakage of the drill bit, and then it will be much harder to pull out. And the torch can break down and burn out, which will lead to unforeseen costs for a new tool.
First you need to carefully detach the drill bit from the tool, taking care not to damage it. Then you need to take another drill bit with a smaller diameter and install it on the tool. Then take your time and carefully drill around the stuck prisoner. There is no need to be in a hurry, all that matters is caution and precise movements. It is important to try not to touch the stuck drill bit, otherwise the second one will break too.
When enough space is freed around it, you can easily pull out the stuck part with your hands.
Using a vice
In some cases, a fairly large vise is used to release the auger. In this case it is obligatory to use standard rubber pads that do not allow the tool to crush the body of the drill.
- Clamp the jammed drill bit in a small vice.
- Lightly tap the bit with a small hammer towards the side and out of the drill bit.
- Wait until the tool is completely wedged out and pull out the bit.
Be careful not to damage the chuck.
A good result with this drill extraction method is achieved by using penetrating solutions.
Tips for avoiding jamming
in order to avoid problems related to jamming of the drill bit in the chuck, it is advised to use only quality tools, which are produced by well known, popular brands. In addition, when working with different materials, it is necessary to correctly and properly select the appropriate work tips. Before prolonged use of the nozzle for drilling a solid surface, it is recommended to first check its quality.
To do this, you need to make several holes in the working surface with the nozzle, and then dismantle it from the chuck. If after the performed manipulations, it easily passes through the shank and is dismounted, then, most likely, such a nozzle is made of quality material and its deformation, in the process of work, should not occur.
Peculiarities in the repair of the barrel peorator
All the described procedures for assembly and disassembly of peorator devices are also true for its barrel variety. But there are a few aspects to consider when repairing it. Placing the motor vertically at right angles to the percussion mechanism slightly changes the disassembly procedure. So, to get access to the gearbox and the piston you need to remove the plastic cover on the top of the tool cover. This makes it easier to repair the mechanical part of the device if the shock function is suddenly lost.
the electric part of such gator is accessible after removing the lower cover. And replacing the brushes is easy because there are holes in the edges of the cup through which they are simply removed.
Electrical Problems: Motor doesn’t rotate, brushes on the collector are sparking, and other types of failures
Dilemmas with the electronic part of the peorator are evidenced by the following signs:
- Motor does not turn on;
- Brushes on the collector are sparking hard;
- There is a smell of burnt insulation coming from the housing;
- there is corrosive smoke coming out of the tool during operation.
In order to find out and remove the cause of all these phenomena, you need to disassemble the torch.
Failures in the mechanical part: the drill bit does not pull out of the barrel, the drill does not chisel, the drill bit does not rotate, etc
The mechanical category of defects includes malfunctions that appear when the engine is running:
- The drill does not chisel;
- drill does not rotate;
- the bit is not pulled out of the barrel (it jams);
- the chisel does not hold in the chuck (it pops out);
- extraneous noises are heard inside the mechanism, squealing, vibrating.
Brushes are sparking
Brush arcing is quite common when working with tools in dusty conditions. Arcing is usually caused by deterioration of the brushes themselves. The situation can be improved by replacing the latter with a new one, sparks will not fly out anymore.
If not, the cause must be found in the stator or rotor windings. It is entirely possible that a huge amount of dust penetrating into the engine has led to abrasion of the protective varnish covering the copper conductors. And this entails a short circuit. The presence of an inter-turn short circuit is checked with an electrical device (multimeter).
Do not forget that dust can stick to the bearing grease next to the manifold. To prevent this, degrease the collector with a swab soaked in alcohol or solvent.
The torch will not spin or drill
If the chuck doesn’t rotate in drilling mode when the start button is pressed, the cause can be identified by the sound beforehand. If the electric motor buzzes but the chuck won’t spin, there is most likely something inside the gearbox that prevents the rotor from turning. What happened to the engine, you have to find out by taking apart the mechanical part of the tool.
If the engine does not hum when you turn it on, it is more likely that the motor is broken. After opening the cover of the unit, find out what exactly caused the phenomenon. It could be a power failure, a broken trigger or a short circuit in the coil winding. With the help of a tester a definite cause is determined and a corresponding repair is made.
The chuck won’t hold the chuck
From time to time it happens that the chuck together with the bit comes off the chuck when the machine is running. This is caused by wear of the cartridge body mount at the end of the bush, which is a retaining ring. If it breaks, its fixation is broken and during the shock the rubber dust cap comes off, followed by the spring and the balls.
The chuck can be restored to normal operation by installing a new circlip. It is very fast and does not need any additional tools beside a screwdriver.

Drill bit does not pound
If the chuck does not kick when you switch to kick mode, but the drill still rotates, it is more likely that the floating bearing is damaged. The solution is to replace it with a new one.
The 2nd probable cause is damage to the hammer mechanism. Quite often the metal striker splits during the overloading at work, it leads at first to the weakening of the blow, and then to its full absence. The bit must be changed.
Wear or breakage of the piston group is the 3rd possible reason. Replace sleeve and piston.
Drill bit does not stay in the chuck and comes out
Failure of the rotary tool assembly may occur in the course of long-term operation. A drill or chisel inserted in the chuck can no longer be held and comes out during operation. Not only is it unrealistic to continue chiseling with this tool, but it is also very unsafe. a chisel that has come off can cause injury.
Chuck wear or chuck breakage is the cause of tool jamming. Take the chuck apart and find the source of the problem. The balls may have become deformed, there may be a breakage on the limiting ring or the fixing spring may have sagged. Usually after the defective part has been replaced, the chuck works properly again.
Remove the chuck due to a jammed drill
A rubber mallet is used when extracting the drill bit from the chuck Many pen holders have to remove the chuck themselves in order to get the drill bit out of it. However, before you start the work, you should familiarize yourself with the list of tools that may be needed to perform it:
There are two most common ways to attach the chuck to the shaft. Most often the threaded method of installation is used. In this case, it is quite easy to remove the design. It is necessary to carefully fix it in a vise and slowly twist the drill counterclockwise. If the design has an additional locking screw, it will have to be removed with a gas wrench.
Some Sturm and Hammer torches use a tapered mount. In these situations, you must place the tool in a vise and gently tap on the bottom face with a hammer. A few taps should be enough to start removing the chuck. When it is removed, you can try to get the jammed drill bit out.

How to release the double-clutch chuck
Double sleeve chuck is used to hold the drill more securely There are some models of peorator that have a double sleeve chuck. Its characteristic feature is that it has no cog, which is responsible for improving the retention of the set drill. The rings in the chuck are absolutely smooth, so it is not very convenient to remove this part. Nevertheless, many people manage to remove it by themselves without assistance. This can be done in the following way:
- Use the holder and gently wrap it around the closest coupling.
- Place the drill in a vice and grip it firmly.
- Use a hammer on the grip. Apply the hammer so that the blow is directed towards the unscrewing side of the socket.
Once you have done this, the chuck must come free with the drill bit.
info! Do not hit the chuck too hard with a hammer too often to loosen it. One precise tap is enough for the ring to begin to move.
To improve sliding, oil can be added. It must be added under the coupling. After that, the cartridge should be extracted better.
Recommendations for Avoiding Such Cases
Wide holes in the wall prevent the drill from jamming To encounter such problems less often, it is necessary to use only quality drills from reputable manufacturers. The fact is that it is with counterfeit products that such unpleasant situations most often occur. That is why you should not skimp on drill bits. It is better to pay more so that you don’t have to pull out jammed drills in the future.
In order to check how good is the quality of the purchased drill, it is necessary to make a few holes with it. If it fits through the drill shank without any problems, it means the product is really reliable and can be used in the future.
Often people encounter jamming when using inappropriate drill bits for working with certain surfaces. In such cases, even high-quality parts can not cope with the load, deformed and jammed. Before you begin, you should be familiar with the function of the drill bit and know what materials it is suitable for.
Drill bit jamming is a common situation encountered by many people who regularly work with a torch. To quickly cope with such a problem, you need to familiarize yourself with the basic ways of extracting a jammed part and understand why this can happen.
Lightly etching the chip with nitric acid
There are situations when a piece of drill bit gets stuck in a hole and cannot be removed using the above methods. In such especially complicated cases nitric acid can help.
Concentrated nitric acid reacts vigorously with many metals, causing rapid corrosion and degradation. Aluminum is an exception. But the alloys from which drill bits are made are not as resistant to nitric acid. This property is used when you want to easily extract a stuck chip from an aluminum part.
The following tools and materials are needed for the reaction:
Use any suitable tool to remove as much as possible from the hole the aluminum shavings, which can clog the screw groove of the drill bit and prevent the acid from penetrating deep into the hole.
Then something between a cup and a funnel is made of plasticine, it will hold acid over the hole and keep it from leaking.
A plasticine cup is fixed over the hole with the stuck drill bit. The acid is poured in. The part is left for several hours.
“That’s how I was able to get the chip out, which I couldn’t loosen and pull out with pliers. Literally overnight the nitric ate almost all the drill bit, there were pieces that I just shook out. The aluminum is left absolutely intact, it’s not damaged in the slightest.”.
- An indication that the reaction is going on actively is the bubbles on the surface of the nitric acid. If the reaction is weak, the part should be heated slightly with a construction hair dryer.
Vetting is used quite often in these applications, but not always successfully. Some craftsmen complain that they cannot achieve the desired effect for several days. This can be due to two problems:
That is why it is recommended to pre-clean the screw grooves of the debris as much as possible and use a plasticine funnel. If you drop a few drops on the drill bit, there will be no active corrosion.
