How to remove a drill from 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.

Extraction methods

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!

How to remove a drill from a hammer drill: expert advice

Construction work now requires the use of various tools, one of which is a hammer drill. With the help of this device, workers make holes of various diameters, as well as dismantle various reinforced concrete or stone structures.

Situations often occur when it is very difficult, if not impossible, to get the nozzle out of the device holder. In this regard, the question arises of how to pull the drill out of the hammer drill without damaging the device. To do this, you must first figure out what causes such troubles.

Varieties and causes of drill jamming in a hammer drill

There are two most common variants of this problem:

  • the drill gets wedged in a drill chuck or in a buffer element, which is used to install an ordinary nozzle in a hammer drill;
  • the product gets stuck in the clamp of the punch itself.

In the first case, the problem appears due to the fact that a drill is required to solve problems, which is used for a conventional drill. For its installation, there is a special product. the adapter chuck is the same as in a conventional electric drill. The clamping element of the punch is inserted into it, after which you can start work.

After their completion, in some cases it is not possible to simply get the drill, since the lips of the clamping device hold it tightly. This problem is quite easy to solve, since its root lies in the misuse of the clamping mechanism. Some craftsmen simply forget about regular lubrication, so the tool wedges.

WD-40 fluid can be used to remove the drill from the rock drill.

In the second case, the drill got stuck in the hammer drill. This trouble appears for completely different reasons than getting stuck in the transition node. The nozzle in the electric drill moves around its axis, in some cases it makes weak reciprocating movements. This is due to the transfer of energy into the tool body through the lips of the clamping mechanism and the bottom of the chuck.

The hammer drill uses a different energy transfer technology, and accordingly, the nozzle in the clamp moves differently. Since the rotary-impact and just impact vectors of the tool movement are provided in the hammer drill. Energy is transmitted to it through a special striker, which is set in motion by means of a power unit powered by electricity. This hammer has a mechanical effect on the shanks of tools installed in the chuck, such as a drill, drill, bit or chisel.

Sometimes a vise is used to extract the drill from the hammer drill.

These elements are equipped with special grooves, with the help of which they are securely fixed in the clamping device. These grooves also serve to provide the tool with the power to rotate. Poor quality tools are made from soft alloys that do not undergo heat treatment. The shanks of such products cannot withstand high and prolonged mechanical loads, therefore they become unusable. In this case, you may have to disassemble the tool before removing the drill from the hammer drill.

Ways to get a drill from a hammer drill

As soon as the drill gets wedged in a concrete wall, floor or any other similar structure, you must immediately turn off the rotation mode, if enabled, and leave only the impact. After that, you need to pull the tool towards you, while pulling it to the other side of the surface in which it is stuck. These movements will lead to the fact that the drill will break part of the concrete layer holding it, after which it should simply and without much effort come out. This method will also help when the drill gets jammed in the wall structure due to the coarse fraction, and if the product gets into the reinforcement.

Another easy way to extract the drill from the surface is to use the reverse rotation feature. This function is not available on all instruments, in addition, its use leads to the licking of the drum assembly of the mechanism. If the device has a warranty, then you can try to extract the drill using this method.

Read about how to choose the right hammer drill in this article. Perhaps you are also interested in what kind of drill bits are for drilling concrete.

There is also a rather extravagant way to extract the borax. To do this, you need a gas wrench. It must be screwed onto the nozzle, and then unscrewed in the opposite direction. This method works because the gas wrench has a fairly long lever with which you can apply a lot of force. But if this method still does not work, you can try to knock on the handle of the key with a hammer. At the same time, the punch should be loosened from side to side. The combination of these movements will cause the drill to come out rather quickly.

In some cases, before removing the drill from the hammer drill, you will have to make several additional holes with another tool. As a result, a large hole should form around the drill, the diameter of which should be about 10 centimeters. The drill will come out together with a fragment of the wall, the resulting hole can be repaired later. This method is suitable in the case when it is impossible to close in the wall or cut the drill.

If none of the above methods came up, then the nozzle will simply have to be cut down with an angle grinder, beat off with a sledgehammer or something to cover up.

Now let’s talk about what to do if the drill gets stuck in the hammer drill. This is most often due to the fact that the material of the shank does not withstand loads and deforms. To remove the tool, it is necessary to clamp it tightly in a vice. After that, it is necessary to turn on the reverse on the instrument, it is advisable to set it to maximum power. The start must be pressed with some interruptions, since long-term operation in this mode will lead to a breakdown of the power unit of the device.

After the product is wedged, the perforator should be abruptly pulled out of the vice. They will contain a drill that is no longer usable. If the vice was not around, you can limit yourself to a thick wooden board. The hammer drill must be set up for drilling, but at the same time turn on the reverse. You need to drill until the tool “bites”.

Boer stuck in the wall: how to pull out?

In some cases, the drill can be firmly stuck in a wall or any other surface of reinforced concrete structures. In most cases, such a nuisance occurs if the hole is drilled at a slight angle of 6 centimeters. There are several ways to retrieve the tool.

Instructions

The first step is to check if the rock drill has a reverse rotation function. If there is one, you need to turn it on and, swinging the tool from side to side, get it out of the wall.

In addition, you can arm yourself with a drill and make another hole near the existing one, and by loosening the punch, remove it from the structure.

If the above steps do not help, you will have to use a gas wrench. If the size is too large, a steel plate can be used as a spacer. The key should be screwed onto the drill and hit on its handle with a hammer from the wall. These movements are not the most convenient, but the method is quite effective.

You can also use a reverse hammer to retrieve the drill, which is easy to find at any body shop. If this tool is not available, you can connect the hammer drill to the SDS connector of the bit and pull it away from the work surface. This method is effective when the drill is stuck at a depth of no more than 10 centimeters.

If the drill gets stuck in the wall while drilling through with very little left until the end of the process, then you can punch the stuck tool with a sledgehammer. It is necessary to beat in the direction of drilling. It is important to remember that you cannot hit the nozzle itself. you must use a board or any other pad to soften the impact on the drill.

To get around these problems, it is enough to remove the drill and drill hole as often as possible and clean it of dust, concrete fragments and other contaminants. In addition, a drill or other accessory can jam in the surface if too much pressure is applied to it, so the tool must be held lightly. If the structure is reinforced concrete, that is, it has metal reinforcement, then there is a risk that the drill will get stuck in it. Therefore, before starting these works, you should check the location of these metal elements with a special device.

In some cases, it happens that the drill jammed the hammer drill. This is usually due to the use of a cheap, poor quality tool. In such products, the fasteners do not withstand the load and are deformed. In some cases, it is enough to clamp the tool in a vice and try to unscrew it. In the most difficult cases, you will have to disassemble the cartridge. To do this, the first step is to dismantle the upper rubber product, as well as the retaining ring, which is located under it.

Recommendations for avoiding such cases

If after these operations the drill can pass through the shank without any extra effort, then this tool is really of high quality. If deformation has begun, then at this stage the product will simply be removed from the clamping mechanism. It is important not to miss the moment when these changes start in order to prevent serious jamming of the drill in the rock drill.

A similar nuisance can also arise from the decision to use fairly powerful equipment for hard objects, but keep the usual drills. Even the highest quality products that are not designed to handle any material will quickly fail and deform. Therefore, for each type of material, special attachments should be used.

It is important to remember that it is not always possible to independently remove the nozzle from the hammer drill. Therefore, you simply cannot do without visiting the service center, which will lead to the loss of the warranty. The fact is that the use of low-quality or unsuitable equipment is a user error.

Reasons for jamming

This kind of problem occurs in two cases:

  • The drill is stuck in the adapter chuck that is used to insert a conventional drill
  • The part is stuck in the clamping lips of the hammer drill.

The first problem occurs due to the need to use a conventional drill in the work of the drill, which requires a special adapter cartridge for manipulation with a perforator. It is inserted into the clamp of the device.

The second reason for the bit jamming may be the clamping of the hammer drill. This kind of interference occurs under other circumstances. The drill bit rotates around the axis, sometimes performing weak reciprocating movements. This happens due to the transfer of power to the power tool through the lips of the clamping element and the bottom of the chuck.

The hammer drill mechanism transfers energy in a different way, so the drill in the clamp moves differently. The instrument has rotary-percussion and just percussion working functions. Energy is transferred to the device by a special striker, which hits the tail of the installed nozzle.

The attachment has special grooves that are firmly fixed in the clamping element, ensuring the transfer of torque. Poor-quality nozzles are made of a soft alloy that does not lend itself to heat treatment, as a result. the tails do not withstand the load and become unusable.

How to remove a stuck drill from a hammer drill?

Repair work most often requires the use of a tool such as a hammer drill. They are drilled holes and dismantled surfaces. Any power tool is subject to stress during operation, and this gradually leads to malfunctions. Often, after the completed work process, a problem arises with the removal of the drill from the tool holder. It takes a little work to pull out a stuck drill.

What to do if the drill gets stuck in the hammer drill?

When, in the process of performing a large amount of work, the drill from the opposite side is riveted, it is not possible to pull it out of the hammer drill freely.

To get the drill out of the power tool, two methods are used:

  • A stuck drill must be taken in a vice, while holding the tool in your hands, loosen it to the sides and pull it towards you.
  • In a large vice, using rubber pads, so as not to crush the body, a perforator is clamped. Then the drill is clamped with a small vise and with a small hammer, blows are easily applied to it in the direction directed to the exit of the equipment from the chuck.

In both cases, penetrating solutions can be used.

If you cannot pull the drill directly out of the chuck during turning, then you need to remove the parts of the chuck or try to turn the drill back 90 degrees. Turning it usually results in a complete replacement of the clamping element components.

If attempts to pull the drill out of the device were unsuccessful, then so that the perforator does not finally break down, it is better to seek help from the master.

The ways

First of all, you should try to take the drill in a vice.

Then the punch is pulled in the opposite direction, while making swinging movements.

When performing these actions, the cartridge itself must be open.

If the drill is not stuck too tightly, this will quickly solve the problem.

The second method also involves the use of a vise. After clamping the drill, you need to start the reverse on the device at the maximum possible power. In this case, you cannot constantly keep the device turned on, you should press the start button with short interruptions. Otherwise, due to long-term operation in this mode, the punch may break.

After the wedging of the tool occurs, you need to try to sharply pull the perforator out of the vice. Then only a drill will be in them, which will not be useful for further use. Instead of a vise, you can use a thick wooden board. Then the drilling mode is switched on on the hammer drill with the reverse switched on. Drilling should be done until the tool “bites”.

Otherwise, you should try the third method. To do this, the perforator itself should be clamped in a vice. During the execution of the action, you need to be especially careful not to damage the body of the tool. You can make a kind of gasket: lay the puncher with rubber or a similar material. After that, you should take a gas wrench (if it is not available, other small vices will do). The tool itself is clamped with it. Now the key is tapped with a copper hammer in the opposite direction from the chuck

The fourth method also involves the use of a vice. After clamping the tool, you need to start reverse on it at the maximum possible power. In this case, you cannot constantly keep the device turned on; you should press the start button with short interruptions. Otherwise, due to long work with a broken shank, the hammer drill may break.

Replacing a Hammer Drill Chuck

Important! If after completing 3-5 movements nothing has changed, then there is no point in continuing these actions. In such a situation, the deformation of the drill is too great, and to remove it, you will have to completely disassemble the perforator.

There is no single disassembly scheme for a rotary hammer, since each model is made according to an individual scheme. If a person has experience in disassembling tools, then he can try to do it on his own. First, the upper rubber cover on the chuck is dismantled, and then the retaining ring, which is located under it, is removed. If there is a concern that the tool will be damaged during disassembly, they resort to the help of a service center.

How to remove a broken drill

The drill can not only get stuck in the chuck of the tool, in some cases it breaks. Then only the shank from the nozzle has to be removed from the device. In this situation, thin-nose pliers will help. Ordinary pliers will not cope with the task, since they cannot be opened inside the cartridge.

The pliers should be inserted into the perforator with little force. Then they need to be slightly opened, grab part of the broken off drill and pull it out. You can first remove the rubber band from the tool to make it easier.

If the device has not jammed the shank, then the chuck is pulled towards itself and the crushing mode is activated. The puncher is positioned upside down. Due to the vibrations that have appeared, a piece of drill will fall out on its own. If none of the methods helps, you will have to disassemble the punch.

The reasons

There are several main reasons why this malfunction can occur.

Among them, two of the most common can be distinguished:

  • jamming of the drill in the chuck or in the buffer element (it is used when installing a conventional drill bit);
  • drill stuck in the punch clamp.

In the first situation, a malfunction occurs due to the need to use a drill, which is needed for the device to function. 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 clamping element of a hammer drill and then start to work.

After completion of the work, it may be difficult to pull out the nozzles due to their tight fixation by the lips of the clamping hole. In this situation, there is a simple and quick solution, because the problem arises from improper operation of the clamping mechanism. Many users forget (or simply do not know) that it needs to be lubricated periodically. For this reason, jamming occurs.

The second situation occurs due to the element getting stuck in the punch itself. The nozzle of an electric drill rotates in a circle, and in some devices it also performs reciprocating actions. This is because the body of the tool transmits an impulse through the bottom of the chuck and the lips of the clamping device.

But in the hammer drill, the energy is transmitted according to a different principle, therefore, the nozzles move along a different trajectory. This tool assumes rotational percussion and percussion vectors of the rig movement. Energy is supplied to the tool through the striker, which is included in the movement after the start of the operation of the power unit connected to electricity. Such a firing pin acts on the shanks of tools inserted into the chuck with the help of mechanics (drill, drill, chisel, crown).

There are special grooves on the attachment, which are securely fixed in the clamping element. This allows them to ensure the transmission of torque. Cheap tips are usually made from low-quality materials and soft alloys that cannot be heat treated. Because of this, the tails become unsuitable for further use, since they cannot withstand such a load. In this situation, you will most likely have to completely disassemble the tool.

What to do if the drill gets stuck in the hammer drill and how to pull it out correctly?

Construction and repairs involve the use of a huge number of devices, a special place among them is the perforator. Using this tool, holes of different sizes are made in any surface, as well as buildings made of stone, concrete and iron are dismantled. Sometimes situations occur in which it is impossible or very difficult to pull the drill (or a piece of it) out of the hammer drill. Therefore, any person who is engaged in repairs needs to know how to pull out the drill without harming the device. And for this, you should study in detail the prerequisites for the occurrence of a malfunction.

If, after completing these actions, the drill passes through the shank without hindrance, then the rock drill is of high quality. If there is a deformation of the nozzle, then it will be quite easy to pull the drill out of the mechanism. The main thing in this case is to act quickly, otherwise the right moment will be missed. After all, jamming will be serious, and it will take a long time to get the nozzle.

The drill gets stuck due to the use of an expensive and high-quality device together with cheap equipment on a hard surface.

Important! Even expensive, high-performance device parts can quickly fail if used on non-intended materials. Because of this, special attachments are used for each surface.

A burr getting stuck in a hammer drill is a common problem faced by every construction worker. It happens for several reasons. Most of the time, sticking occurs due to the use of cheap tools or equipment for them. It is better to play it safe once again and take all possible measures to prevent the problem. If it has already occurred, they try to remove the drill from the perforator using a vice. No need to be afraid of getting stuck! When you can’t get the drill yourself, you should contact the service center for help.
