How to get the drill bit out of the drill without a wrench

There are a number of reasons why an electric drill can jam.

The most obvious cause of failure, it is a factory defect, this problem is most often found in very cheap and low-quality drills. That is, tools from Bosch, Makita, Metabo, Interskol will be less likely to be defective. This is why such equipment is popular.

Even the most reliable tool can fail if not used properly

And here it does not matter which manufacturer. the same Bosch or Makita are even more prone to failure if used improperly

This reason is not tied to a particular brand or parameter of the tool, but some brands provide for this point and make protection from inexperienced users.

If you use or store the tool improperly, the main part of the drill can break easily. This is a very common problem, but you can’t call it a defect.

In the first two cases you won’t be able to fix the tool at home. In the case of the third problem, you can fix it yourself. But first you need to determine the type of chuck.

How to open the drill chuck?

The purpose of a drill chuck is to hold a drill bit or other attachments (construction mixer, grinder, etc.) securely in place. д.). Locking is achieved by three mechanical “pins” that are brought together and apart by the threaded mechanism.

There are two main varieties of chuck:

  • Keyless type. To open such a design, it is enough to embrace the body with the fingers and, turning on the reverse rotation, briefly press the trigger of the tool. The drill will rotate the shaft by itself by moving the “fingers” that fix the drill bit. This chuck is easier to work with, but will be somewhat less secure in holding the tool.
  • The keyed version. The key is a T-shaped device, one end of which has a tapered toothed gear. The other two ends serve as handles for turning. To unscrew or screw in the chuck, the wrench is inserted into the hole on the housing and rotated, holding the housing with the other hand.

A spanner is generally supplied with the power tool. It either lies in the box or is attached to the power cord with a special fastener.

Working irregularities

Safe drilling practices involve certain rules, but failure to follow them can result in injury or damage to the tool. The drill chuck is in the greatest danger as it takes the brunt of the contact with the surface. To avoid unpleasant consequences, it is not recommended to change the angle of drilling sharply. It is also necessary to limit the applied force on the drill, the drill bit of which is in the process of drilling. Overloading can cause the drill bit to break or jam in the chuck. Heavy-duty applications require drill bits designed for heavy-duty applications.

Design features

The main types of chucks for household drills are as follows:

  • Quick-chuck or BZP, convenient in operation, allowing you to easily and quickly change the tool, but the strength and durability are not too high; however, drills with quick-change chucks (with one or two clutches) are deservedly popular;
  • gear-wheels, requiring the use of a special wrench.

There are also other varieties, such as SDS and SDS-max from Bosch. But it is not necessary to dwell on this question in detail, because the type of chuck on the way of clamping the drill does not affect the way of fastening the chuck to the spindle of the drill.

Chuck fastening on the electric drill spindle

Actually, there are two ways to attach it:

The marking on the chuck shows the type of fastener:

  • marks B10, B12, B18, etc. п. are characterized by parameters of Morse cone, a special form of mating surfaces (in total there are 9 standard sizes from B7 to B45); before this designation mark a range of diameters of shank drills, for example, 1-6 B10;
  • type designation 1-15 M13×1,3; characterizing metric thread parameters (drill bit shank diameter, thread diameter and its pitch);
  • UNF abbreviation (the full marking is similar in structure to the metric thread marking, for example, 2-13 mm ½. UNF, where ½ means thread diameter in inches, and the number 20 characterizes the number of threads per inch length), which means fixing with an inch thread; this type of connection is typical for imported tools.

Technology of chuck removal from an electric drill

The following tools may be required to perform this operation:

The tool is removed from the chuck beforehand. The keyhole chuck can also be unlocked without a wrench by inserting the drill bit shank into the hole.

Disassembly in the case of cone mating

This option of coupling should not cause any disassembly problems.

If there is a fixing screw, unscrew it.

It is recommended to orient the tool down and remove the chuck by light hammering (to protect mechanisms from damage, a better option is to hit with a rubber or wooden mallet on the body of the chuck through the spacer. horn-key).

If a bearing removal tool is available, it is best to use it.

Disassembly with a screw mating

In this case the disassembly procedure is as follows:

  • The cams are pushed in as far down as possible since the head of the internal screw is on the bottom of the cam cage and must be reached with a screwdriver. However, a screw is not compulsory.
  • Use a screwdriver to remove the screw from the spindle, the fixing screw has a left-hand thread, i.e. it can be unscrewed by turning the screwdriver clockwise. If you have difficulty turning the screw, you can lightly tap it with a hammer via a screwdriver.
  • The socket can be unscrewed from the shaft like an ordinary nut with a right hand thread, that is by turning it counter-clockwise. If the process is difficult the use of two spanners is recommended. Use the open-end wrench to fix the spindle and the gas wrench to unscrew the chuck. A thicker allen key can be inserted in the jaws and the chuck can be unscrewed with this.

If you still can not perform the operation, you will have to dismantle the body of the drill to provide access to the spindle.

One more tip: if the screw is damaged during disassembly, you can buy an adapter for the torch and it will come with a suitable screw.

You can learn how to remove the chuck from drills of different companies (particularly Interskol) by watching the video.

These recommendations are also valid for torches and screwdrivers.

  • Before any work on the repair of the drill it is necessary to disconnect the power cable from the mains.
  • If the case is complicated enough or there are doubts about his qualifications repairman appliances, it is better to ask for help from professionals. Otherwise there is a risk of ending the repair by buying a new drill.

How to remove the drill bit from a drill without a wrench

What repair can you do without a good drill and a set of drills?! However, even the most reliable tool during work can jam. Don’t panic! We teach you how to change the drill bit in your drill and how to diagnose other malfunctions.

Drill Arrangement. What You Need to Know About the Tool?

Drill bit jamming in the chuck of a drill or electric screwdriver has happened at least once with every tool owner. To understand why this can happen, you need to understand how your drill works.

This tool converts electrical energy into mechanical energy, which is possible thanks to an electric motor that unwinds the shaft.

Through the gear and gears, the rotation is transmitted to the fixture, in which the drill is fixed.

Now let’s look at the reverse side of the electric drill, assuming that the drill bit was not attached properly or not securely enough.

The oscillations that occur during operation will cause deviations in the drilling direction, and you will get a crooked hole as a result.

Vibrations from vibration will be transmitted to gears and reduction gear, will catch the shaft and the motor itself. it won’t break right away, but it will reduce the tool’s service life! Often negligence in fixing the drill bit and leads to its jamming. Sometimes jamming occurs as a result of the drill bit slipping from the drilling point. to avoid this, use a spring-loaded punch to make notches on the surface for the drill bit.

Besides jamming, a loose drill bit can jump out of the fastener, and this is already fraught with enough severe injury to the person working with the tool and those around, given the speeds of modern devices. So never fasten the drill hastily, always switch off the power for that, to avoid accidental starting of the drill.

The fixing device is a non-drill chuck

The chuck is the name of the fixture in which the drill bit is fitted. The fastener itself screws onto the tool spindle. Drills are most commonly fitted with a cam-type chuck.

This construction is a hollow cylinder with metal studs inside.

Turning the adjusting ring on the outside of the knot causes the “fingers” to pull together or pull apart on the inner cone-shaped surface.

Both cylindrical and hexagonal shank drill bits can be clamped in this “knuckle.

Convenience and ease of use have made the cam-type mechanism very popular. But it is not without its disadvantages. One of them is the difficulty in working with small drills.

A short product can simply fall in. You can still fix it by putting the drill in a horizontal position, but you can’t put too much pressure on it while it’s working.

If another drill bit has been inserted in the drill, it can be removed by turning the adjustment ring in the appropriate direction.

You can’t always do it by hand, that’s why there’s a special wrench that acts like a lever, increasing the force.

By the way, to tighten the drill without a wrench is also not recommended. the larger the diameter of the drill, the more reliable should be the fastening.

When you buy the fastener, make sure it is rubberized, so you will injure your hands less when you fasten the tool.

The second most popular quick-action fastener can be used without a wrench. It is enough to insert the drill bit and turn the lever, often this can be done with one hand.

True, it does not add convenience, but there is at least some confidence that you do not have to look for a wrench throughout the construction site.

How to change a drill bit in an electric screwdriver? The scheme is absolutely identical. the chucks in most drills are similar to the fasteners on screwdrivers.

Of course, the latter tool can not be a full-fledged replacement of a quality drill, if only because the fastener is not provided for drills with a large diameter, and the speed of an electric screwdriver, as a rule, less.

How to change the drill bit in a drill. do it yourself!

It is not always possible to remove the drill bit from the chuck in the usual way. as a result of a heavy load or improper fixation it can jam the chuck.

So how do you get the drill out of the drill without damaging the fixture or the tool itself?? First of all try to cool the chuck down sufficiently.

Sometimes it’s enough for the cams to let go of the drill bit a bit so you can pull it out.

The most proven way to get a jammed tool out is to tap the jaws.

To do this, the free end of the drill is fixed in a vise, a wooden bar is attached to the chuck, through which the tapping is carried out.

From such vibration, the chuck can loosen its grip and release the tool. This method is useful both for owners of classic fasteners and owners of quick-change chucks.

Sometimes extraction is possible after lubricating the drill bit with machine oil or the popular WD-40 grease.

The latter method is better, because due to the atomizer the substance will reach the desired points of contact between the drill and the chuck faster.

In any case, you have to wait a little longer after greasing to allow the substance to penetrate deeper.

Sometimes, in particularly complex cases, the problem is solved only after dipping the entire chuck in machine or vegetable oil.

If neither is available at hand, you can make a “bath” of your drill and gasoline. Keep the chuck in the liquid for at least one hour. With a combination of methods you will get the jammed drill even faster.

How to replace the chuck. renewing the drill

often than not, it is the chuck that comes in disrepair first in the drill.

Not easy to remove at home, but possible! The fastener is screwed onto the spindle itself, but besides that it is also fastened with a left hand threaded bolt.

In order to get it out, you have to unlock the chuck completely. it’s inside.

The whole difficulty of unscrewing it lies in the fact that many people do not know about left-hand threads, and trying to unscrew it, they screw it up even more, tear off the cap and end up carrying it to the service.

The essence of opening with a wrench

If everything is working properly, getting the drill bit out is easy. There are 2 types of cartridges, key and keyless. With the second, everything is easier: you just need to turn on reverse on the drill, lock the chuck in your hand and gently press the trigger. In this way everything is unscrewed and the drill can be inserted.

Key access to drill.

Key access. a special small tool is inserted into the grooves of the drill, then rotated counterclockwise. The unscrewing works like a gear. the cogs unscrew the chuck.The wrenches are usually included in the delivery of the drill, some are inside the box and some are directly attached to the wire. But what to do if the key is lost?

How to remove the old cartridge

Chucks that are fastened to the spindle with a thread are normally also fastened via a left-hand threaded screw for more security. For this reason the chuck must be removed first by unscrewing this screw. Before unscrewing it, clear a path for the cartridge. To do this, the chuck jaws need to be retracted as far back as possible.

If you now look in the chuck, you can see a screw head for a Phillips or star screwdriver in the center of the bottom. To prevent this screw from coming loose it is made with a left handed thread. So, unscrew it by turning the screwdriver to the right side, having previously clamped the assembly in a locksmith’s vice.

It is possible that the screw splines have become clogged over the years of operation and in order to catch the screwdriver bit, it is necessary to turn it and at the same time easily tap on it with a pair of pliers or a hammer until you feel the hook.

After removing the left-hand threaded screw, insert the hex key into the chuck and tighten it.

Clamp the free side of the hexagon in the jaws of the vice and use a suitable socket wrench to tear off the nut on the drill, which fastens the chuck to the spindle of the tool.

After that, you can release the L-shaped hexagon from the vice and by turning it to the left, completely unscrew the clamping unit from the spindle shaft.

How to remove the quick-action chuck from a threaded drill

The particularity of the chuck-shaft connection is the left-hand thread of the fixing screw. This is done so that by rotating the drill bit and “digging” into the material, the shaft simultaneously tightens the chuck mount. Consequently, the answer to the question of how to remove the self-clamping chuck from the drill of this type is simple. you need to rotate the chuck, firmly holding the body, in a clockwise direction.

Usually, just rotating is not enough, you have to tap the connection to make the threads tightened too much to loosen them a little and allow them to freely rotate the connection.

Drilling in different materials

To drill quickly and accurately metal surface

, choose the right drill bit. the sharpening of the cutting edge differs significantly, as well as the steel grade from which the cutting tool is made. When working, it is necessary to set low speed, and the pressure must be strong, but so that the drill does not break. The place of the intended drilling is marked with a locksmith’s core. You need to make a small hole so that the drill firmly grasped the metal and does not “walk” on its surface.

When you drill in concrete or brick, you must switch on the impact mode and always use a respirator, because the impact is too great. к. there will be a lot of dust.

In order to drill through tiles

, Some craftsmen use a thin wooden board. On the tiles mark the place of the hole, then we put a wooden pad and carefully drill so as not to crack the delicate surface.This method can be used to drill tiles in the bathroom or kitchen, the drill set to maximum speed.

When it is necessary to make large holes in wood

, If you want to use a drill bit with a larger diameter or special attachments. Some specialists use a powerful, but low-speed drill (no more than 600 rpm) for screwingscrew piles On the homestead. Installation is carried out by gradually pressing into the ground with the simultaneous screwing of the preassembled pile structure, while using special wrench heads of different diameters.

Performing repair work most often requires the use of a tool such as a peorator. It is used to drill holes and dismantle surfaces. Any power tool is subject to load during operation, and this gradually leads to malfunctions. It is not uncommon to have a problem with removing the drill bit from the chuck of the tool after the work process has been completed. It takes a little bit of work to get a stuck drill bit out.
