How to replace the chuck in a hand drill. How to remove a chuck from a drill: video, how to change a quick-release chuck, disassemble and replace it, Interskol and Morse with a cone

You have to remove the chuck from the electric drill to clean or replace it. The dismantling process itself is simple, and sometimes difficulties that arise can be solved. Our guide clearly shows how to properly remove the chuck from a drill with your own hands.

Methods for attaching cartridges

Hand drills use two types of drill chuck mounting:

  1. Morse taper - a conical shaft shank and a corresponding hole in the chuck.
  2. Threaded fastening - a thread on a shaft onto which the cartridge is screwed like a nut.

Take a close look at the metal rod between the body and the cartridge. In the case of a threaded fit, the slots for the open-end wrench are usually visible, and the tapered shaft is always smooth.

The method of fastening is also indicated by the markings stamped on the cartridge:

  1. The Morse cone is designated by the abbreviation B10, B12, etc. (B is the cone, the number is the maximum drill size).
  2. The marking of the threaded cartridge contains a designation of the type and diameter of the thread: M13 (metric by 13 mm) or UNF-1/2 (inch by half inch).

Removing the threaded cartridge

For drills with a reverse function, the drill chuck is additionally secured with a locking screw, visible through the open jaws.

The slots on the screw head can be cross-shaped, hexagonal or even star-shaped. Prepare the required screwdriver, wrench or bit. Use a tool with complete splines that fit exactly.

Measure the size of the wrench space on the drill shaft. Most likely, it will be 14 mm for a mid-range tool or 17 mm for a more powerful device.

Prepare an open-end wrench with thin jaws. You can take a suitable one from a bicycle repair kit or grind off the edges of a regular key using sandpaper.

Hold the drill shaft with a wrench and try using a screwdriver to unscrew the screw clockwise (left-hand thread).

Try not to tear off the splines.

If the thread does not work, secure the electric drill chuck in a vice and hit the screw head several times with a hammer through a steel rod.

Now the thread will become more pliable and the screw will come loose.

Difficulties may arise. Try increasing the leverage by holding a hex wrench in the chuck.

As a last resort, use a vice, placing a drill in it as in the photo below.

Move the cartridge from its place by striking the driver secured through the square head.

This method makes it possible to unscrew fairly strongly stuck cartridges.

After cleaning, install the cartridge in reverse order, remembering different directions thread.

Apply a little paint to the threads before tightening the locking screw.

Specifics of cone fastening

In modern hand-held electric drills, the Morse taper is rarely found. Such models are equipped with special pullers, and the dismantling process is displayed in the technical description.

In old Soviet drills, the design of the gearbox made it possible to remove the chuck using rather crude methods. One could try to separate the conical surfaces with a wedge-shaped object, lightly knocking it from different sides.

Another option was to take the drill with one hand with the chuck facing down, and with the other to apply light blows to the end with a hammer. If that didn’t help, we lubricated the landing site with a penetrating compound (kerosene or WD-40), let it sit for several hours, and tried to knock the cartridge off again.

This method can be used if the shaft bearing is installed inside the housing. For most drills used today, this method is unacceptable, as it can lead to damage to the bearings or gearbox.

When selecting a new chuck, pay attention to the type of fastening, bore diameter and the ability to operate in impact mode, if your drill has this option.

How to remove a chuck from a drill from 4 manufacturers

What could be simpler - replacing the drill chuck! But even here, difficulties may arise for those who will change the cartridge for the first time. A drill is a construction tool that has several functions, depending on the attachments on it. It can be used to drill holes of any diameter in various types materials, you can screw in or unscrew screws, use it as a mixer for mixing liquid construction mixtures. They are angular and standard, networked, battery-powered and pneumatic. They are widely used in construction, repairs and in everyday life.

Where is it better to use a keyless chuck?

An important component of the drill is the chuck - it clamps the drill of the required diameter and ensures correct rotational movements drills. There are types and varieties of chucks, depending on the method of clamping the drill - using a special key (used on powerful tools) and a keyless chuck. There are a huge number of drill manufacturers.

The keyless chuck for drills began to be used quite recently, and until that moment this type of electric and hand tool was equipped with a jaw-type chuck

With frequent use, every electric tool requires periodic service(prevention) and repair, regardless of:

  • Manufacturer;
  • Power;
  • Appointments;
  • And a power source.

With such a chuck, the required drill can be clamped in a couple of seconds without the use of additional power tools. By applying the effort of one hand, the head rotates, and you need to turn the chuck, and the drill socket will increase, thanks to which you can pull out the unnecessary drill and insert the suitable one.

The quick-release chuck is convenient to use both in construction and at home.

Then, by turning the chuck, turn the cylinder again and fix the desired drill for work. If you change drills frequently, the chuck connector may become unusable and the drill will spin, complicating the work process. In this case, it is necessary to replace the cartridge.

There is a bolt inside the cartridge; you need to unscrew it using a screwdriver. There is a peculiarity here - you need to unscrew it in the opposite direction from the usual - to the right. If the bolt is difficult to unscrew, you can try to fill it with liquid key - it is quite possible that rust has appeared inside over time. After this, use a jerk to unscrew the cartridge directly. There are options when it is necessary to fix the axis on which the part is attached.

Disassembly of the drill chuck is carried out in accordance with safety regulations. The first thing to do is unplug the drill.

To do this:

  • It has special grooves;
  • In this case, the axis will have to be secured with a key;
  • And then with a sharp movement unscrew and remove;
  • Next, you need to secure the new cartridge.

Before replacing, it is advisable to lubricate the axle so that problems do not arise next time. There should be no inconvenience during assembly. The main thing is not to forget to screw the bolt back in - we remind you that it is also screwed in an unusual direction - to the left. You can now continue using the drill.

It is important to compare drill chucks in the store before purchasing, as they may differ slightly in thread.

Sometimes situations arise when the breakdown of a drill is not related to the chuck connector, but something has gotten into it or is jammed. In this case, it is necessary to remove the cartridge (this process is described above), and then disassemble it for cleaning.

Instructions: how to disassemble a drill chuck

The instruments are popular in Russia and the countries of the former Soviet Union in view good quality and inexpensive prices. The Russian manufacturer, which produces both a drill-mixer and a screwdriver, distinguishes between impact and non-impact drills. The percussion is distinguished by the presence additional function- striking movement.

First, the top nut with teeth is unscrewed. You can use a gas wrench, but this must be done carefully so as not to damage the nut

Depending on the chosen model, it varies:

  • Electric motor power;
  • Chuck diameter;
  • Rotation speed.

The simplest and effective way parsing looks like this: You need to take a hammer drill, remove the boot from it, install the adapter and put the chuck on it, which was previously removed from the drill, press the chuck against the wall, not forgetting to put a rubber shock absorber between them.

Be sure to hide the cams located in the chuck (elements directly involved in clamping the parts) inside - screw them in.

Next, press it against the wall and turn on the hammer drill in impact mode. That's it, the cartridge is disassembled. We clear it of debris with which it was clogged - it is optimal to lubricate all the insides before assembly. Important point– do not mix up the jaws in the chuck; each jaw must be in its place.

Steps: how to remove the chuck from an Interskol drill

The Interskol drill has a number of advantages. It is light and easy to operate; when working at heights, it is possible to hang it on a belt, thereby freeing your hands. You can change the number of revolutions.

To remove the cartridge in the Interskol drill, you need to clamp a thicker hexagonal L-shaped key. Hit the long end of the key clockwise with a sharp, sharp blow

First of all, it stands in the most inexpensive segment in comparison with such competitors as:

  • Bosh (Bosch);
  • Makita;
  • Metabo et al.

There is a function for fixing engine speed: press the switch lever all the way, then press the lock button and release the lever. The speed will be fixed and you can continue to work, at this time you can concentrate not on the pressure of the drill, but on the material you are working with.

There are non-standard options removing the chuck from a drill, for example, not all Interskol drills have special grooves in the axis for fixing with a key.

The main thing is to never hit the cartridge with a hammer or other tools when unscrewing - you can break not only the cartridge, but also damage the axle. So, first of all, you need to unscrew the bolt, as usual. Next, you can take a gas wrench, grab the edge of the part that needs to be removed, and either jerk or use slow progressive movements to unscrew the cartridge. In order to avoid the problem of the inability to remove the cartridge in the future, be sure to lubricate all parts with lithol or other lubricant.

Analysis of a drill with a Morse taper

There are drill models that use a chuck not with jaws (jaw chuck), but with a threaded connection (or Morse taper). You can choose an adapter for it, or continue to work with this cone - it all depends on preference. In order to repair a drill or screwdriver, it is important to decide which cartridge. Appearance theirs is similar, so you need to look at the markings that are stamped on the surface of the part. If the cartridge is marked with the letter B, it is a device with a Morse taper. In this case, you can remove the cartridge using a drift and a plumber's hammer.

Not everyone can disassemble a drill with a Morse taper

It is also important to know about threaded chuck the fact that it comes in 2 types: inch (typical for models foreign production) and metric (produced by Russian manufacturers).

Every Soviet electric drill and screwdriver has a clamping drill chuck with a left-hand thread; sometimes disassembly is necessary if the self-clamping cone shaft is jammed, or you need to remove the machine attachment, change the screw, repair or the fastener is stuck. Including the drill needs correct use and timely prevention.

With this tool you can drill:

  • Plastic;
  • Tile;
  • Tree;
  • Concrete;
  • Metal;
  • Brick and other materials.

Most often, a rotary impact drill is used at home. It includes a cartridge of the SDS system, which was invented by Bosch. Such a system is not characterized by particular accuracy. For more precise drilling, there are adapters that consist of jaw chucks.

How to remove a chuck from a drill (video)

When choosing a drill in a store, pay special attention on the chuck - it determines which attachments you can use during the operation of the tool. It is also important to remember that when frequent work a situation will arise when it is necessary to remove the cartridge, and you will need to clean it, lubricate it yourself and replace it. Therefore, to prevent problems with removal in the future, it is advisable to unscrew the new drill and lubricate all parts with lubricant.

Electric drills use a special device called a chuck to securely hold the drill bits. In household drills, jaw chucks are the most widely used type. With intensive use, they may fail and require replacement or repair. Problems often arise during these operations. So how can you remove the chuck from the drill shaft, disassemble it into its component parts and replace it with a new one?

The role of the chuck in reliable fastening of the drill

Clamping drill chucks for household drills are available in three modifications:

  • key;
  • quick-release;
  • gear-crown.

The body of the key jaw chuck is made in the form of a hollow, hardened cylindrical sleeve (collet), on the outer surface of which a rotating adjusting collar is installed. On one side the cylinder is mounted on the drive shaft of the drill, and on the other side there are cams (petals) for attaching cutting tools (drills, taps, reamers, etc.). When the adjusting ring rotates, the steel cams move along guides using special threads. If they come close to each other, the drill is clamped. If they diverge from each other, the tool is released. The approaching and moving away of the cams depends on the direction of rotation of the holder. Reliable fixation of the drill is ensured by tightening the chuck holder with great force. To do this, use a special key or a quick-clamping - on quick-release chucks - clutch.

The key helps to firmly clamp the drill and easily unscrew the adjusting collar. Drills of various diameters with a cylindrical shank are fixed in jaw chucks. Most often, household electric drill chucks are designed for drills with a diameter of 0.8 to 10 mm or 1.5 to 13 mm.

Why and when do you need to change?

The clamping device must ensure that holes are drilled with acceptable accuracy. But over time, the seats on the shaft and cams wear out, and the cartridge begins to beat. That is, the working area of ​​the drill begins to move from side to side when rotating, and the hole is drilled with deviations both in location and in diameter. Wear on the cams does not allow the drills to be securely fastened, and they stop under load. There is only one way out - replace the worn cartridge with a new one.

How to replace the chuck in a drill with your own hands?

To attach the chuck to the drive shaft of the drill, a threaded connection or Morse taper is used. Visual inspection electric drill will not always help you suggest a way to secure the drill chuck. This can be indicated by the marking on the cartridge: it is stamped on its surface.

Replacing the conical type of part

The standard size of the Morse cone (according to GOST 9953–82) consists of 9 values: from B7 to B45. How higher figure after the letter B, the larger the diameter of the cone.

Thus, having found the marking “B” on the surface of the cartridge, we can conclude that this is a device with a conical mounting base. With this method of attachment, the cartridge can be easily removed. It is enough to use a drift and a plumber's hammer.

Replacing the reversible threaded chuck

To secure the drill clamp to an electric household drill using a threaded joint, two types of threads are used:

  • inch (for foreign models);
  • metric (from Russian manufacturers).

The following marking is applied to the surface of the threaded clamping chuck body: 1.5–13 1/2 – 20UNF or 1.5–13 M12x1.25.

The reversible threaded cartridge for fixation has a screw with a left-hand thread. You need to know this nuance when filming broken cartridge. In order to get to the screw head, it is necessary to recess the cams into the collet completely. As soon as the head of the screw is visible, use a hardened Phillips screwdriver to unscrew it to the right clockwise. Then hold the hex key in your fists and hit it sharply in a counterclockwise direction. After the cartridge is torn from its place, it can be easily unscrewed.

On other models there are other options for mounting the cartridge on the thread. In some cases, the cartridge is twisted entirely from the threaded end of the shaft. In other cases, the screw can be fixed with a special thin key using a narrow groove. The main difficulty is to move the cartridge from its place when unscrewing. Sometimes this is very difficult to do. In any case, to remove the cartridge you need: a mechanic's tool, the necessary skill and patience.

Disassembling a drill chuck with a quick-release nut

To clean the jaws and lubricate the moving parts and threads of the cartridge, it must be disassembled. Disassembly is necessary to repair and replace failed parts. Here is a short list and sequence of operations for disassembling the jaw chuck:

  1. The removed cartridge with the conical part up, lined with wooden spacers, is clamped by the coupling in a vice.
  2. Use a gas wrench to carefully unscrew the notched nut.
  3. The bearing is pulled out. The puck comes out.
  4. The cartridge is removed from the vice.
  5. The adjusting sleeve is twisted from the base by hand. If it does not give in (jammed), then the cartridge turns over and is again compressed by the clutch in a vice. A little machine oil is poured onto the threaded part of the coupling and base. Then, using a gas wrench, the base is skillfully unscrewed from the coupling.
  6. If there is a retaining ring or nut at the bottom, they are removed.
  7. The cams are pulled out of the guide rings and removed from the base cone.
  8. All parts of the drill chuck are carefully inspected. If worn, deformed or broken parts are identified, they are rejected and replaced.
  9. The jaw chuck is assembled in the reverse order. At the same time, all moving parts are lubricated with a special grease. It is best to use the lubricant recommended by the manufacturer.

The procedure for disassembling cartridges of other models may be different. It depends on the type of chuck, its design and the manufacturer of the drill. To disassemble the drill chuck yourself, you need to fulfill three conditions:

  • have the necessary set of tools available;
  • have plumbing skills;
  • to be a person with a stable, balanced psyche.

Possible problems with the chuck when operating a drill: causes, descriptions and ways to solve them

To avoid problems with a drill, you need to be able to operate it correctly. A drill is a universal tool; it can be used to drill wood and metal, plastic and tile, stone and glass, concrete and brick. In everyday life, a rotary impact drill of medium power is usually used. It is equipped with a chuck of the SDS system, which was invented by BOSH. The SDS chuck is not particularly accurate, but is ideal for drilling concrete, stone, and brick. That is, those building materials, where drilling is necessary with impact.

For more precise drilling of metal and wooden parts, it has a special adapter for attaching a clamping cam key or keyless chuck. A drill cannot be used for milling work. Drill chuck It is not designed for side loads and will quickly fail. Of great importance is:

  • correct choice of drill;
  • correct sharpening of the cutting part of the drill;
  • mandatory marking of the center of the holes using a core.

You need to skillfully select the desired speed, feed, operating mode depending on the workpiece material. All these factors directly affect the reliable operation of the drill chuck.

The part falls off

Does the cartridge fly off? This problem occurs quite often even on new drills with a cone-shaped jaw chuck when drilling a deep hole. You need to lift the drill to free it from the chips, and at this moment the chuck flies off the cone. The situation can be corrected by increasing the tension in the cone joint. To do this, the chuck is heated in oil or oven to a temperature of 110 degrees and placed on a cold drill mandrel.

Clamping jaws jammed

Drill work always takes place in dirty conditions. This is dust, dirt, shavings, sawdust and other small debris. If this debris gets inside the chuck, it can cause jamming. threaded connections, in particular, at the cams. There is only one way out here. Requires disassembly of the cartridge, cleaning and rinsing of moving parts. Before assembly, all moving parts are lubricated with lithol. Especially a lot of waste is poured into the chuck when drilling ceiling surfaces. Here you can think about protecting the cartridge with half a small rubber ball.

Runout

Chuck runout can be caused by various reasons. For example, the Morse seat cone is worn out. This can be checked using paint. An even layer is applied to the cone and the cartridge is inserted. Then the mark he left on the cone is removed and studied. Another reason could be uneven wear on the cams. In this case, they need to be changed. But more often they replace a broken cartridge with a new clamping device.

In the right hands, a household drill can work wonders. With its help, holes are drilled in durable and soft materials. The chuck is an important component of a drilling machine. It is this that ensures the reliability of drill fastening and drilling accuracy. Therefore, it is very important for a home craftsman to be able to independently carry out minor repairs and replacement of this part of the device.

The drill chuck can be represented by several types, which differ markedly in design and design features. It is quite possible to quickly replace such a part of an electric drill with your own hands, but you need to know the basic rules for performing such work.

Drill chuck: device and types

A significant part of drill models are equipped with so-called cam devices. This option is a hollow cylindrical body, on the surface of which there is a movable part in the form of a ring or control sleeve. One cylinder base is attached to the drill shaft. The second base is used to fix the attachments. The process of rotation of the adjusting ring causes the movement of cams made of metal. The approaching and moving away of such cams depends on the direction of the annular rotation.

To secure it to the shaft, the housing is equipped with a special convenient threaded hole or has a special conical surface. There are also types of cartridges that are best suited for equipping specially designed rotary hammer models. It is quite possible to remove and change it yourself. Cam-type drill chucks allow you to secure the attachment and shank within standard limits of 0.8-10 mm and 1.5-13 mm.

In order to ensure maximum security during fastening, it is very important to tighten the cartridge with significant force. Cam chucks can be:

  • “regular”, represented by “key” or “gear” options;
  • “quick-clamping” or bzp cartridge.

To tighten or loosen the adjustment ring on a “regular” device, you will need to use a special wrench.

Characteristics of the drill keyless chuck

Tightening and loosening will require the use of a special metal sleeve that is knurled or grooved. Quite often, a plastic sleeve with ribs is used for this purpose.

The main difference of this element is the absence of a clamping key and the use of an outer shell that allows clamping of the drill lips. Most often, the use of BZP is accompanied by the following problems and difficulties:

  • insufficient quality of drill clamping;
  • lack of sufficient resistance to dust;
  • breakdown of the clamping mechanism.

Drill chucks: varieties (video)

If the mini drill or screwdriver model comes with special type blocker, it is necessary to use a single-sleeve clamping element. On tools without a blocker, a two-clutch element or a mini-chuck is used. As a rule, the body of such a device is made of plastic, and a steel alloy is used to make the mechanism and cams.

Any option self-execution repair work requires knowledge of the device and main components:

  • cone-shaped gripping lips;
  • inner part with lips;
  • external clamping part.

If necessary, each individual element of such a device can be replaced, for which it is necessary to disassemble the device correctly.

How to remove and disassemble an electric drill chuck

Even small, minor repairs will require proper disassembly of the structure. Today, there are only two mounting mechanisms on the working shaft, so the dismantling process may vary.

At threaded method fastening, the structure must be disassembled in the following order:

  • deepen the cams inside the body and spread them as far apart as possible;
  • Unscrew the fixing screw located in the central bottom part of the device. Fasteners with left-hand threads must be turned clockwise;
  • Using an open-end wrench placed on the shaft, the device is unscrewed.

If there are no flats, the housing is disassembled, as well as the rotor shaft is subsequently fixed in a vice. It is advisable to unscrew the element using a gas wrench.

The most popular and frequently used in modern instruments is the cone connection. In addition to the exceptional strength of the cone connection, this option the right approach You can disconnect it yourself quite easily. To this end the body is first tapped in a circle, after which the element is knocked off the shaft using a sharp and precise blow to the rear of the shaft.

After the cartridge is removed, it is necessary to correctly determine the type of malfunction. You can carry out repairs yourself if there is no significant damage to parts or jamming. caused by metal shavings trapped inside adjacent parts. As a rule, restoring functionality in the event of such a breakdown can be achieved by washing the elements in oil or kerosene using a soft, medium-sized brush. After this cleaning method, assembly is carried out in the reverse order.

Most often, owners of actively used tools are faced with a number of malfunctions caused by wear and damage to threaded or toothed parts. Minor local damage of this type can be easily eliminated by grinding. For this purpose, it is recommended to use a needle file or a standard sanding cloth. In the most difficult cases breakdowns most often require a complete replacement of the failed cartridge.

How to remove a chuck from a drill (video)

For dismantling and self-disassembling the cartridge electric drill you need to prepare a set of tools presented:

  • vice;
  • pliers;
  • screwdriver;
  • hammer;
  • small mallet;
  • chisel;
  • needle file and sandpaper;
  • a brush with soft bristles and an oiler;
  • a set of gas keys;
  • adjustable wrench;
  • awl;
  • file;
  • caliper.

The basic version of the tool set may vary slightly depending on the type of connection and the complexity of the dismantling work performed. Excessive force should not be used since in this case not only the external, but also the internal working part of the device can be irreparably damaged.

Replacing a drill chuck with your own hands

There are several most common problems that can be observed during the operation of the tool, and will require cartridge replacement:

  • quite often a fixed element falls. This problem occurs not only on old instruments, but also on completely new models that are characterized by conical fastening cam part. As a rule, falling of a part accompanies the process of drilling deep holes. In this case, when lifting the drill and freeing it from accumulated chips, the cartridge falls off the cone. This problem can be solved by increasing the tension of the cone joint. For this purpose, you need to heat the cartridge in oil to a temperature of 110 o C, and then place it on the fixing part of the cold tool;

  • If, when performing work that is accompanied by the release of a significant amount of dust, chips or dirt, the clamping lips jam, then you need to properly disassemble the chuck, and then carefully, but as thoroughly as possible, clean and rinse all moving, working elements. Before assembling the part, it is very important to lubricate the internal parts with a brush and lithol. A good result is obtained by using a homemade protective casing that prevents clogging of the working parts;
  • If chuck runout is observed during drilling, the cause may be significant wear on the seat cone. An equally common cause of this phenomenon can be uneven wear of the cams, which must be replaced. If necessary, the broken cartridge is completely replaced.

Reassembling the disassembled part is carried out in the reverse order of disassembly, observing the rules for fastening to the tool.

How to change the chuck in a drill with your own hands (video)

The chuck is one of the main components of the electric drill mechanism, so the performance of the tool and the quality of the work performed will depend on its condition. It is quite possible to replace such a device yourself even without the skills and special knowledge, but in this case you need to correctly determine the cause of the breakdown and follow the standard instructions for repair work.

What repair would be complete without a good drill and a set of drill bits! However, even the most reliable tool can jam during operation. Don't rush to panic! We will teach you how to change the drill bit in a drill and correctly diagnose other breakdowns.

Drill design - what do you need to know about the tool?

Every tool owner has had a jamming of a drill in a drill or screwdriver chuck at least once. To understand why this could happen, you need to understand how the drill works. This tool converts electrical energy into a mechanical one, which is possible thanks to an electric motor that spins the shaft. Through the gearbox and gears, rotation is transmitted to the fastener, in which the drill is fixed.

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 rotation modern devices. Therefore, never fasten the drill in a hurry; always disconnect the drill from the current to avoid accidental starting of the drill.

Fastening device – non-combat cartridge

The chuck is the fastener in which the drill is fixed. The fastener itself is 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 you turn 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 hexagonal one.

Convenience and ease of use have made the cam mechanism popular. However, it is not without its drawbacks. One of them is the difficulty of working with small drills. Short product may simply fall inside. You can still secure it by placing the drill in a horizontal position, but you can’t put too much pressure on it while working. If another drill was 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 purpose there is a special key that acts like a lever, increasing the force. By the way, it is also not recommended to tighten the drill without a key - the larger the diameter of the drill, the more reliable the fastening should be.

When purchasing fasteners, make sure that they are rubberized - this way you will be less likely to injure your hands when securing the tool.

The quick-release fastener, the second most popular, can be operated without a key. Simply insert the drill and turn the lever; this can often be done with one hand. The drill fixation that this type of chuck provides is quite sufficient for most jobs, however, compared to classic version fastenings it is inferior in reliability, and it costs more. The main advantage of a quick-release fastener is the speed of drill replacement and the safety of the process, since such a chuck is devoid of teeth that can injure your hands. The absence of a specialized key is also a significant advantage! Experienced builders know how easily it gets lost, so very often you can see a key taped to a wire with tape or tape.

True, this does not add convenience, but there is at least some confidence that you won’t have to look for the key throughout the construction site. How to change the drill bit in a screwdriver? The scheme is absolutely identical - the chucks of most drills are similar to the 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 lower.

How to change a drill bit in a drill - we can do it ourselves!

It is not always possible to remove the drill from the chuck in the usual way– as a result of heavy load or improper fixation, it may jam the cartridge. How to get a drill out of a drill without damaging the fastener and the tool itself? First of all, try to cool the cartridge thoroughly. Sometimes this is enough for the cams to release the drill a little and you can pull it out.

The most proven method for removing a stuck tool is to tap 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 cause the chuck to loosen its grip and release the tool. This method will be useful for both owners of classic fasteners and owners of quick-release fasteners. Sometimes removal becomes possible after lubricating the drill with machine oil or the popular WD-40 lubricant.

The latter method is better, because thanks to the spray, the substance will quickly reach the desired points of contact between the drill and the chuck. In any case, after lubricating you will need to wait a little for the substance to penetrate deeper. Sometimes, in particularly difficult cases, the problem is solved only after dipping the entire cartridge into a machine or vegetable oil. If neither one nor the other is at hand, you can make a “bath” for your drill from gasoline. You need to keep the cartridge in the liquid for at least an hour. By combining methods, you will be able to remove a jammed drill even faster.

How to replace the chuck - updating the drill

Most often, the cartridge is the first to become unusable in a drill. Dismantling it at home is not easy, but it is possible! The fastener is 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 out, you need to completely open 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 when trying to unscrew it, they twist it even more, tear off the cap and eventually take it to the service center.

By unscrewing the bolt, you can also unscrew the cartridge itself, although this is not so easy to do. Some models have recesses at the base of the thread for a wrench - in this case, you can fix the spindle and unscrew the fasteners using a lot of force. The real difficulty comes when there are no wrench cuts. You will have to remove the housing cover to secure the spindle inside the drill. Difficult, but doable.

Removing a cartridge is one thing. Finding a new one is a completely different matter.
