How to insert a drill into a hammer drill
Drill stuck in a hammer drill. how to pull out?
Hello everyone! In this article I will tell you what to do if a drill is stuck in your hammer drill. how to pull it out and how to prevent it from happening in the future. Many users of this technique have encountered this problem. Some even broke their instrument because of this, which, of course, I do not wish for you. There are two main ways to remove the drill if it gets stuck in the chuck. They are quite simple and we will definitely consider them below. But first, I think it would be better to consider the reasons for the jam.
Reasons for jamming
Why is a low quality shank flattened or bent? Flattening occurs due to the fact that the perforator mechanism itself is made in such a way that a special firing pin constantly hits the shank, which is accelerated by a pneumatic mechanism located inside the body. I wrote about this in this article of mine. The blow has a rather large force, which is why steel of poor quality cannot withstand. In addition, some do not use drill lubricant, which causes the liner to overheat, making the liner flatten even easier.
And if we talk about curvature, then its reason is quite obvious. The drill, going deep into the material, begins to experience more and more resistance. And if it is larger than that for which the steel from which the drill is made, then its bending may occur, including in the area of the shank.
These are the reasons. Now that we have considered them, we can proceed to actually extracting.
First you need to try to clamp the drill in a vice, and then pull the puncher towards you, making various movements to the side. Naturally, do not forget to hold the cartridge in the “open” position. If the deformation is small, then this method will most likely be able to carry out the removal. If the extraction fails, try the following trick.
So, the next technique is to fix the perforator itself in a vice. This should be done so as not to damage the case, so it is better to lay some kind of rubber gaskets. Holding the tool, take a gas wrench or a small vice and squeeze the drill with something from them. Now, with a copper hammer, knock on the key or a small vice, whichever you use, in the opposite direction from the chuck. If the extraction did not happen in 3-5 strokes, then you can not try further, since obviously the deformation is very strong, in which you cannot do without disassembling the perforator.
Disassembly of a specific instrument model is always individual, so there is no universal answer. If you are not afraid and generally have experience in disassembly, then you can try to do everything yourself. But I still recommend contacting specialists at one of the service centers. For a reasonable fee, service providers will do the job.
This concludes the article. I wish that the drill can be removed without any problems and I advise you to use high-quality equipment. Well, see you soon!
A few tips for using the tool
It would be useful to remind you how to work with a hammer drill. This information will be useful for novice builders.
- Use protective equipment during work: ear plugs, gloves, goggles.
- Do not exert force on the rotary hammer during operation.
- Idle mode of operation of the device is inadmissible.
- If the processed material has increased hardness, then it is necessary to apply a lubricant. Ordinary machine oil can serve as an alternative to lubrication.
- When using a long drill, the drilling must be made shorter.
- To increase the service life of the tool, it is necessary to periodically cool the drill in water or oil, take breaks from work.
The hammer drill firmly entered the life of the builder and installer today. This tool, with due regard to it, will serve for a long time.
What is a puncher
With the widespread use of the hammer drill, construction and repair work has become much easier. Indeed, in cases that require drilling holes in concrete, brick, asphalt, this device is irreplaceable. Wherever hammer drilling is required. It is also used for drill-specific tasks, although the hammer chuck is different.

This tool has three standard features:
- drilling without impact;
- drilling with a special hammer drill;
- punching holes with chisels, lances or blades.
Another difference between a hammer drill and a drill is that it has a lot of power. It starts at 700 W and goes up to 3 kW.
If the nozzle is stuck
As with any tool, even the best quality hammer drill can jam. When performing work, this becomes a problem, which has several options and reasons.
Firstly, when the drill is stuck in a removable chuck, and secondly, if the nozzle is jammed in the hammer drill itself.
When the problem is in the clamping of the tool itself or in the removable head, it is enough just to pour a little liquid of the WD-40 type into the chuck and wait a little. The composition will relax the grip of the clamping device and the drill can be reached without problems.
The cause of a malfunction is also in the poor quality of the drill itself. If a cheaper and softer metal alloy was used in the manufacture, then the drill bit can damage the drill during operation.
There are several ways to fix this problem. The first thing to try is to clamp the drill in a vice and, holding the tool in your hands, loosen the bit and pull it towards you. If the deformation is not very serious, then the nozzle can be pulled out.
The second option provides for double fixation with a vice. a perforator on one side, and a drill on the other. Then they take a small hammer and hit the drill in the direction of the exit from the clamp. With this operation, you can use the WD-40.
When none of the methods helps, you can try to remove the parts of the cartridge and turn the drill in the opposite direction about 90 degrees. However, such a technique can completely ruin the parts of the clamping device.
But if this option did not work, it is better not to try to disassemble the device. It is better to give such a perforator to the workshop to competent specialists.
It should be noted that in order to minimize the possibility of such breakdowns, it is better to choose high-quality tips from leading brands. As a rule, such an investment pays off with a long tool life.
The nozzle can get stuck not only in the mechanism of the unit, but also in the wall during operation. In this case, you can try to free the drill or drill by turning on the reverse stroke (reverse) on the device.
If this method does not work, then the nozzle is released from the clamp, another is inserted, and, after drilling the wall around the stuck tip, remove it. If the drill breaks during operation, then its remnants are removed from the clamp, and a piece stuck in the wall is drilled out or simply cut off with a grinder at the same level with the working surface.

How to save the key jaw chuck
If the reason is only mild corrosion or a deformed drill, you will need a gas wrench, chisel or screwdriver and a 700 g hammer:
- Spray rust converter, grease or machine / any mineral oil into the chuck.
- Let stand for 5-20 minutes.
- Hold the chuck with a gas or plumbing wrench so that the drill is on the left hand.
- Fix the structure with a vise, clamp or just feet.
- Place the screwdriver on the clamping ring, in the groove between the teeth, tilting away from you.
- Deliberately hitting the handle of the screwdriver with a hammer, causing the ring to twist.
If you have two gas keys, you can try to turn both rings in different directions at the same time.
Tip Be sure to inspect the cartridge: there are no grooves, dents or other defects left on it and inside. If so, it is better to change the attachment. Open the chuck as far as possible and unscrew the screw on the “bottom” to remove the nozzle.
Removing the debris with pliers or tweezers
The easiest option is when the drill breaks directly at the surface of the part or even above it, and at least a small protruding tip remains, which you can grab onto. In this case, you can remove the chip with pliers.
“The most convenient way to grasp the tip of the drill is not with ordinary pliers, but with the so-called long-nose pliers or thin-nose pliers. Their notched clamping part is narrow enough so that the jaws can pass between the drill turns and fix them securely. “.
The jaws of the tool must be inserted into the hole and grabbed by the screw groove of the debris. Then you need to unscrew the drill in counterclockwise movements.
If the drill is very thin, you can do the same with tweezers. Corrugated tweezers for electrical work are best suited for this purpose.
Features of the
With the help of a hammer drill, you can make a hole in almost any material. This device is most often used when working with concrete, brick and metal, less often with wood.
The variety of materials assumes several modes of operation and a large number of attachments:
The main difference is their purpose.
Drill nozzles are designed for drilling punching operations with high strength materials. In this case, the hammer drill performs not only drilling, but also impacts or vibrating actions. Drills make neat holes of the required depth and diameter in the surfaces. Crowns are used for drilling large holes. For example, under an outlet. Installing a chisel or blade assumes that the tool works like a jackhammer.
A significant difference is the type of attachment, which for all attachments, except for drills, is suitable exclusively for a hammer drill, since it has a landing tail, mounts in the form of grooves for this tool.

But you can also fix a conventional drill from a drill in a hammer drill. This requires an adapter called a removable chuck. This device is of two types:
The name of the type itself determines the type of drill clamping mechanism. The cam clamp is driven by a special key that is inserted into the thread on the outer perimeter and turned. In this case, the collet mechanism, installed inside the chuck, is compressed or unclenched, depending on the direction of movement of the key.
The quick-clamping type is operated by small hand force. Pressing the chuck downwards opens the drill hole.

Extraction using a strong electrolyte
You can remove a piece of drill with a strong electrolyte (nitric acid) only if it is stuck in the aluminum.
How to use hamar drill machine. How to install and open drill bit.
- Lubricate the fragment with an aqueous solution of nitric acid. After a while, the electrolyte will corrode the chip.
- Drive out a stuck piece of metal with a locksmith’s pick.
It is important to carry out all actions at an ambient temperature of at least 20 degrees Celsius.
We hammer a pipe into the ground
Heavy perforators. weighing over 8 kg and blowing up to 20 kJ, are used when clogging an Abyssinian well. A galvanized pipe with a sharp tip is placed vertically and, using the hammer mode, driven into the ground. Of course, the diameter of such a pipe cannot be large (up to 1 inch). But even this is enough to provide an average family with water. This method is used when installing water intake in places inaccessible to heavy drilling equipment.
Removing the working tool
To remove the drill or nozzle after work or for replacement, you must:
- Wait until the rotation of the chuck has stopped completely.
- Pull the base of the chuck down until it stops.
- Remove the drill from the chuck.
- Release the base of the chuck.
Attention! The drill gets very hot from friction. Use gloves to avoid getting burned.
Choosing the right drill
Before you can learn how to insert the gimbal into the hammer drill, you need to choose the right one. Steel for gimbals is different. made of carbon, high-speed and alloyed metal. If you need to make the hammer drill super-hardy, it is equipped with a drill with a special, hardy soldering.
- for working with wood;
- with glass;
- concrete and stone.
Interestingly, the manufacturers of rock drills have thought about the color of the workpiece. It means the following:
- Black indicates that the metal has been steam treated.
- If the gimlet was painted in a golden or brown hue, it was released to get rid of internal tension.
- The bright rich golden color defines the titanium nitrile treatment. It is this type of gimbal that is considered the most reliable, wear-resistant.
Manufacturers, who care about the quality of the products sold, print on the packaging of parts not only the name of the company, but also the brand of steel, the material for which the workpiece is intended to work. If the gimbal overheats during operation, it has become dull or improperly sharpened.
Chucks used by the tool
How to insert a drill into a hammer drill? The SDS cartridge was invented for quick installation of the nozzle and its change. This mechanism was developed in the 30s of the last century. To fix the drill in the device, you just need to insert it, slightly turning it, feel for the grooves and snap it into place. The SDS mechanism aligns the balls with the shank slots and locks it securely. In order to remove the nozzle back, you need to push the chuck towards the perforator body and pull out the drill. To make the shank fit easily into the chuck, you need to lubricate it with graphite grease. This will also improve the sliding of the balls into the grooves. Repeat the procedure as the grease dries.
If the drill is stuck
It happens that in the process of operation, an unlubricated shank leads to seizure. The fixing mechanism is packed with drilling dust and the drill cannot be pulled out. What to do in this case? No need to panic or immediately run to repair. The use of penetrating lubricants will solve this problem. These products are available in aerosol cans and have a low consistency. Therefore, they operate in places that are difficult to access. To remove the drill, you need to inject grease directly into the drill hole and leave the tool alone for 10-15 minutes. Then, with smooth, rocking movements, remove the drill.
It must be remembered that before inserting the drill into the hammer drill, it is necessary to lubricate the shank. This will save the patron for years to come.
Possible cartridge malfunctions and their elimination
A common malfunction of the cartridge is the impossibility of fixing the nozzle. The inserted drill flies back during operation. There is a simple reason for this, and everyone can fix it on their own. To do this, you need to disassemble the cartridge:
- Remove the rubber boot by prying it off the end with a small flat screwdriver.
- Remove the retaining ring with the same screwdriver.
- Remove the plastic boot.
After that, the entire mechanism becomes visible. Most often, such a malfunction is caused by wear of the steel ring that fixes the balls of the SDS mechanism. Constant shock loads wear out the ring walls, rendering it unusable.
To eliminate the cause, replace the retaining ring with a new one. Then put everything together in reverse order.
Drill chucks are not designed for shock loading. What if it is out of order? To begin with, determine the nature of the breakdown. If the key slips when tightened, then you just need to replace it. In the event of a malfunction of the internal mechanism, it is necessary to replace the cartridge itself on the shank. To do this, you should:
Before you insert the drill into the hammer drill with a new chuck, you should check its performance.
Additional tool features
In addition to the above, the standard set of options in a modern rock drill include:
- a ruler to determine the depth of the hole;
- lever for fixing the operating position of the start button;
- safety clutch. stops the motor when the drill gets jammed.
And also in the design of each device there are systems:
- dust removal. impeller on the engine with a system of dust extraction channels;
- vibration damping. special springs between the body and the power unit;
- electronic regulation of the operation and monitoring of the condition of the brushes on the collector of the electric motor.
An important rule, non-observance of which can lead to failure of the hammer drill. Switching modes should be carried out only when the tool is completely stopped.
What to do if the drill does not move
It is not always possible to quickly pull the working tool out of the hammer drill. If the gimbal is stuck in the chuck, repeat these steps:
- Clamp the free remainder of the bit in a vise, tap with a hammer on the chuck jaws, placing a guide made of wood.
- The tapping should be stopped when the tail of the stuck gimbal appears from the keyless chuck.
- If this manipulation does not give a positive effect, dismantle the cartridge and put it in gasoline. Automotive oil is dripping into the key cartridge.
It is not uncommon for the drill to get stuck in the wall during construction work. This happens when the part is clamped with concrete and reinforcement. Do not pull the trigger. It is also impossible to loosen the perforator. the tool may break. What to do, experts suggest:
- Remove the bit from the chuck.
- Replace with a new one.
- Knock out the concrete that has accumulated around the drill.
- Take care that the tool does not touch the stuck gimbal.
