Drill chucks

Tapered sleeves are very rare, but if you have one of these, you probably want to know how to remove it. Often old electric drills and drilling machines have a taper type mount, so if a chuck has failed on the tool, you will need to do the following to replace it:

  • Spread the jaws apart and unscrew the locking screw with the right thread (the tapered ones have screws with regular threads)
  • Secure the tool, and taking a hammer in hand, apply light blows to the back of the unit
  • After each impact, turn the male coupling clockwise
  • If the inner mechanism is rusted, you should use WD-40 grease before you work on it
  • There are cases when even the grease does not allow you to solve the problem, so you should use a blowtorch, warming the part to red
  • If even in this case, the chuck can not be disassembled, then the last option remains. is to disassemble the drill, and grind the sides of the device on an emery. Some craftsmen prefer to saw with an angle grinder the actuator right on the tool

With a barbaric approach to disassembly, the element is no longer repairable, and after disassembly, it is necessary to install a chuck of similar design. To put a threaded chuck on the drill, you will need to make changes in the design of the drill, which is also quite realistic to do with their own hands.

Now let’s consider the method of disassembly of the part in order to repair it later. The method of disassembly is simple, and does not require the use of a sledgehammer or angle grinder. The main condition must be met. the absence of corrosion on the threads. The principle of dismantling the tapered chuck from an impact drill is as follows:

  • Bring the jaws inside the workpiece
  • Place the tool on a flat surface (table)
  • Press a piece of styrofoam (high density foam can be used) to the end of the tool
  • Press a piece of dense material such as a board or metal against the styrofoam
  • Set the impact mode on the drill. If the drill does not have an impact mode, then to disassemble the chuck, it must first be secured to the torch
  • Firmly press the construction against the chuck, and press the start button
  • In about 10 seconds the chuck with cone-type mount will unscrew and unscrew the chuck by itself

Drill chucks with Morse taper are collapsible, so if one of the jaws fails, they can be replaced. This is the only type of chuck on a drill that can be disassembled, and if the cams or locking sleeve fail, it can be repaired. If the chuck has to be reassembled, it is just as easy to do. To do this, it is necessary to press the outer cage on the clamping sleeve, and then install it on the tool axle. The video below shows how a drill chuck can be disassembled with a hammer.

What it is for?

The drill chuck is an important part that is responsible for securing the tooling. It is designed to hold the drill firmly without releasing it, even at high torque. The chuck can be used to turn a screwdriver or any other tool.

The keyed element assumes that an additional component is used for replacement. The key is made in a T-shape and is located near the chuck. When turned, it moves the gear, which causes the collar to rotate around the lock responsible for opening or closing.

Sometimes in the chuck design, the user turns the sleeve at the end of the drill to open and close the lock cams. This type of attachment holds the work tool better and is easier to tighten by hand, using less force.

On some locks, the chuck design has up to six cams, and the more there are, the tighter the drill sits in its place. Of these, 4 are needed to hold the square bit. If the tool is used for household tasks, then there are 3 cams, and they’re self-centering.

The tool also has a carrying case, which makes it easy to transport the drill. Owners are flattered by the workmanship, balance and lightness. Customers are pleased with the five-year warranty. The tool has proven itself in drilling holes, as well as in work with various attachments.

On the one hand the case is convenient for storage of the drill and accessories, but the manufacturer has saved on plastic. The hinges and clasps are very thin, so the durability of the case is questionable.

Types of chucks

Let’s start with the fact that the peorator in its essence is a percussion machine that does not drill, but punches holes with the cutting part of the nozzle with simultaneous turning it. The collet locking mechanism used in drill clamping devices is not suitable in this case because of the very high loads. Therefore, in order to securely fasten the accessories of this power tool, we had to develop a unique chuck with a special shank, which has special grooves for centering and preventing twisting of the bits.

The evolution of this design element of peorator has been quite active, but to date, the most reliable are considered SDS (steck-dreh-sitzt) clamps, developed by “Bosch. If translated from German, this phrase sounds like “insert-turn-sewer”.

It is this expression that almost completely describes the principle of operation of a modern chuck for a peorator:

  • press the protective cover to release the locking elements in the form of slots and locking balls/rollers, and then insert the shank of the tool with special slots into the hole of the clamping device;
  • release the cover and slightly rotate the tool until a slight click is heard, which “informs” the owner of the power tool that the device mechanism has successfully locked (the slots and balls are in the grooves on the shank) the drill, drill bit, etc.д.;
  • try to remove the bit from the chuck to make sure it is locked in place correctly;
  • To remove the tooling from the tool is carried out in the reverse order (we press the protective cover and take out the nozzle).

the most common type of chuck that today’s torches are equipped with is not only a quick-action chuck but also a quick-release chuck for work with the bit. At the moment there are several varieties of SDS clamps, each of which has its own characteristics.

In addition to this, all existing clips for torches can be divided into two large groups. Non-removable cartridges are considered to be the most reliable. But the removable clamping devices can be quickly exchanged for the combined toothed-ring (key) or collet-type quick-action chucks, if the owner intends to use the tool as a drill.

Attachment methods

The chuck on the shaft of an electric or manual drill is fastened in two ways. cone connection and thread, so there are a minimum of varieties. In practice, there are devices with metric or inch threads, and on the body of the product, even the smallest is necessarily present marking.

For example, the designation of this type 1,5-15M13x1,2 is deciphered as follows:

When using an inch thread. UNF and indicates the diameter: 1/2″. This type of connection is considered international and is used in all tools of foreign manufacturers. For extra security, a stopper is put on the shaft, in the form of a screw on the left thread. this should be considered when confused, how to disassemble the chuck of an imported drill. It should be unscrewed only clockwise.

The second method uses a Morse cone, which today is more commonly referred to as a tool cone. The shaft has a tapered part at the end, on which the device is mounted, with a small amount of force to be applied for a tight connection. The marking is as follows: B10, where the letter indicates the use of the cone, and the number. the diameter of the tail of the cutting tool. This type of fastener is common in screwdrivers.

Some drills are equipped with an adapter (adapter) for the clamping mechanism, which allows you to drill with maximum accuracy.

Bosch (Germany)

The company gives preference to modern SDS-plus type quick-clamping devices. The company clearly divides its products according to the type of intended use. for wooden, concrete, stone and brick surfaces.

Accordingly, each type of chuck for Bosch rotary tools is made of special alloys and has a specific size. In addition, all the tooling supports the reversing option. Other advantages. ergonomics, low weight, long service life, impact mode.

About the attachments for the peorator

In theory it is possible to fit an SDS-max chuck with a tool shank for SDS-plus chucks and even tools with an even smaller shank diameter. To solve this problem, a special nozzle (adapter) is used, which can be purchased at almost any construction market today. Meanwhile it is categorically not recommended to use such adapters for peorator as using a smaller diameter tool on heavy class peorators will quickly lead to its uselessness.

As a rule, the tool is sold in packages at once and can not be recovered after failure. It should not be confused with conventional drills, which differ from it in the shape of the sharpening and the structure of the spiral.
