Chuck for drill: how to remove, replace, disassemble - video, photo
Among domestic masters the most common drill chucks for two species - the key (rack and girth) and quick-action (BZP). Features of operation of these cartridges, we try to understand this article and comprehensively cover all the basic nuances and complexities of working with them.
The most common for household drills and screwdrivers are rack-and-girth and keyless chuck
The main types of drills for cartridges
By design, the clamps for drills are divided into two main types:
- comb-girth chuck, the tool shank in which the clamp with a special key;
- keyless chuck for drills (BZP), wherein the clamping sleeve actuated by its manual rotation.
Variety of ammunition for drills
Clamping jaw chuck mounted on modern drill reliably fix the tool shank which is in the range of 1-25 mm. Devices of this type virtually without drawbacks, the most important of which is their rather high cost.
The most popular type of clamping device, installed on the current models of drills, a keyless chuck (BZP). To lock the tool in the chuck BZP category, it takes a few seconds, with no need to use a special key. Clamping tool shank is carried out by manually rotating the adjusting sleeve, the external surface of which is coated ribbed facilitating the implementation of this procedure. To control the mechanical effect produced on the tool shank has a special locking device in the clamp of this type.
For fixing the drill in one hand are holding the lower sleeve, and the other is tightened clockwise upper sleeve
The most significant disadvantages of BZP include the fact that in cases where the elements of its mechanism of wear, it is not sufficiently fixes the drill shank of a large diameter. This leads to the turning of the tool during operation.
Compared with clamping devices BZP category, rack-and-girth ammunition to equip the drill tool provides a secure fit in any situation. Users who often have to work with an electric drill, prefer chuck is of this type. The only significant disadvantage of such devices is the key with which they operate, is easy enough to lose. Meanwhile, this kind of problem can easily be avoided if, immediately after the acquisition of a drill to fix the key to the wire device with tape or the usual ropes.
The diameter of the nozzle shank clamped in the mini-cartridge depends on the caliber of the collet
Very popular and cartridge for mini drills, mounted on a compact drilling unit. Last actively used by masters of jewelry. Mini-cartridge is classified as keyless chuck for easy screwdriver or drill. Such a small cartridge, which is produced predominantly from brass, is used for fixing the tool shank which is in the interval 0,1-4,5 mm.
Design and features rack-and-girth holder
Classic chuck for drills relates to a clamping device or a cam type collet. They can be clamped not only the various tools with a round shank, but the cylindrical shape of the preform for further processing. The main structural elements of the clamping jaw chuck are:
- a cylindrical shell;
- adjustment ring or sleeve, rotating on the outer surface of the housing;
- a cam mechanism or a collet mounted in the interior of the enclosure.
The design of the cam (rack and girth) with a key holder
In turn, the collet mechanism, which elements are made of hardened steel, is composed of three absolutely identical cams which, when the rotation of the adjustment ring or sleeve simultaneously approach each other, thereby ensuring reliable clamping of the tool shank. In early models of cartridges for mechanical drills collet jaws converged by rotation of the adjusting wheel, it is now used for this adjustment sleeve.
One side for drill chucks are mounted on the shaft of the equipment used, and the other in which the tool is inserted, by means of which the processing will be performed. Clamping jaw chucks are mainly used to lock them in the following instruments:
Rotary drill chuck for clamping nozzle with a cylindrical or hexagonal shank
Removing the cartridge with threaded connection
The question of how to remove the chuck from the drill, which is fixed to it by means of a threaded connection, there is in domestic masters often enough. Shoot a clip should be based on the fact that it is installed using a non-standard left-hand threads.
Threaded element of the clamping device is in its interior, so you must first push the maximum clamping jaws that provide access to the fixing screws that unscrewed using a conventional Phillips screwdriver. The drills without such a screw holder simply curl up with their shaft without performing the above preparatory work.
The head of the locking screw can be Phillips, slotted, Allen key or 'asterisk'
Left-handed screw, by means of which the drill is fixed threaded chuck, can wear out over time. To restore the reliability of such a connection, you can perform the following steps:
- insert a Phillips screwdriver into the chuck of the screw head on the drill;
- light hammer blows to deepen the screw into the threaded hole.
Such actions will not harm the attach drills, but allow it to record on the clamping device more accurately and reliably.
Replacement of the threaded type drill chuck can be performed and by means of key 14, which greatly facilitates this process. In order not to make mistakes when you are going to disassemble the cartridge of this type, you can pre-acquainted with the theoretical material on the topic and view the corresponding video.
Replacement and dismantling of the cartridge to the drill
On the question of how to replace the wear on the drill chuck, no big deal. It's enough to buy a suitable clamping device, remove the old drill and install a new on it. It should be borne in mind that as usual, and the mini drills cartridges can be installed in two types:
Cartridges, for mounting on a drill which thread is used, are removed and are fixed to the above scheme. When replacing such a device is not enough to know that it is threaded, it is important to also consider labeling that is mandatory applied to him. Labeled such chucks are as follows:
Marking threaded cartridge
Interval 1.5-13 present in the designation data indicating the minimum and maximum diameter of the installed cutting tool. Terms of cartridge replacement to drill suggest that a new clamping device must be labeled completely identical to the old designation.
The question of how to replace the cartridge at a tapered drill, everything is a little bit easier. In devices of this type various marking may also be applied, namely:
Marking chuck with morse taper
To be replaced by a drill chuck of this type, you just need to pick up the clamping device with the appropriate labeling and insert it in the landing of the tapered hole drilling equipment. Oriented in such a labeling simple enough: the letter "B" means that this cartridge is cone-type, and the number refers to the diameter of the bottom of the planting hole.
Removal from the cone-type drill chuck is carried out is as simple as installing it. To perform this procedure, you just need to knock the clamping device from the bore drill, which uses a conventional hammer. The details of installation and removal of an electric drill chuck cone can also meet by viewing the corresponding video.
On the Soviet drill chuck with a tapered fixture just emboss, gear design allowed such rudeness. To remove the cartridge contemporary models need to use special tools or pullers
How to disassemble the cartridge screwdriver or a drill? This procedure is necessary to periodically perform maintenance device (cleaning and lubrication of all internal elements), as well as its small repairs. This can significantly extend the life of the cartridge life.
When disassembling the cartridge should be considered, it refers to what type. Focusing on the instructions or video, it is necessary to perform all the steps of disassembly of the device as carefully as possible to prevent damage to its components. After all the procedures for maintenance or repair of the cartridge elements for drill performed, perform its assembly in the reverse order.
If the components are worn out and recover them is not possible, replace the entire mechanism is better, much cheaper than repair.

How to replace the cartridge at drill
Frequent operation of drills, both professional and domestic use, entails a deterioration of some of its parts. In particular, there is a deterioration of the cartridge, resulting in problems such as loss of drill bits, the bit beaters during operation. As a result, it has to be periodically tightened tightening chuck so as not to injure during the working process. Remedy this situation you can use the removal and replacement of the cartridge, but how - do it, learn from this material.
All drills, screwdrivers and drills to secure the working parts are equipped with cartridges, the operation principle of which is based on the cam mechanism. Fixed bits, drill bits and other auxiliaries in the cartridge by clamping them between three and sometimes four cams combinable. The cams are tapered construction which is moved only in the longitudinal direction by rotating the adjusting spetsgilzy. There are two types of cartridges:
Key chucks carried by the tool fixing spetsklyucha application, but at a sufficiently quick-drills manual efforts for securing the working nozzles. Depending on the quality of drill production, as well as the frequency of its use, the term cartridge life depends. Wear cams, so the cartridge is not in a position to fix the working tip. Repair of the cams can not be, therefore, the need to remove the cartridge is to replace the worn-out part, and thus revive the drill.
Key holder on a drill with a special key
Cartridge in infrequent cases extracted from the instrument when it is stuck or drill bit. Rotation of the cartridge relative to the tool shaft is also the negative effects, which can be eliminated only if the reverse cartridge and replace it with a new one. Must be replaced as a keyless chuck in which the jaws have a shorter life, and the key, different from the first maximum tightening force working nozzles. Hammer drills are equipped with only the key drums, as fixing the tool to them much more reliable.
Keyless chuck on the drill
To carry out works to dismantle the cartridge, replace it, as well as for removing a jammed drill bit, need to make sure you have the following required tools:
1) and vice pliers.
3) and pipe wrench keys.
4) Phillips screwdriver.
As you can see, these tools are available for every man in the garage, so remove and replace the cartridge in the drill can be their own hands.
Removing a jammed drill bit from the chuck + (Video)
If you are faced with the problem of jamming of a drill, it is not in all cases it is required to extract the cartridge disassembly. When the drill is jammed in the cartridge, it is possible to remove it by applying clutches.
Drill necessary to clamp in the grip in the horizontal position. Casing drilling is also necessary to fix it to be fixed. On the surface of the cartridge and the knock sleeve must first lightly hammer and applied after bounces. Attempts important to apply on the sleeve in the direction of the tangent plane. Work continues to hammer until the drill bit will not be released from engagement with the chuck.
If using a hammer drill can not release and untwist cams, then you can use a pipe wrench. Casing drilling and jammed drill bit is fixed in a vise, and gas or tong holder made from turning in a clockwise direction. You can also use two pipe wrenches and, having carried out a single tool clamping shaft drill, and the second attempt to scroll the clamping member.
Mounts: what they are + (Video)
The clamping mechanism is attached to the drill shaft by means of the following methods:
In a threaded joint construction is often used an additional locking screw, shown in the picture below. With it ensures reliable locking of the cartridge.
Chuck key and a locking screw threaded connection
A threaded connection is provided by identical thread on the tool shaft and the channel of the gripping mechanism. Considerable importance is the type of thread used in the connection, and they come in metric and inch. Thread on the drill used is indicated by special abbreviations, which has the approximate form:
Abbreviated as follows:
If the instrument is used inch thread markings, the abbreviation for UNF. In modern models of drills used inch thread type, since the choice of clamping mechanisms inch thread is much more extensive.
Shaft for reliable fastening of the clamping mechanism is equipped with a locking screw, which is threaded with left-hand thread. Therefore, unscrewing the screw for removal of the cartridge is performed in the clockwise direction.
Less common way is to mount the chuck by a clamping mechanism based on the use of a Morse cone. In this case, the shaft is conical, and the clamping mechanism is equipped with a similar shape in the inner channel. Fastening mechanism occurs under the influence of the power device pushed on to the motor shaft design tool. Marked by such mechanisms using the following abbreviations: B10, B12, B18 etc..
Key holder for a drill with a tapered connection (labeling)
The letter designation indicates marking cone, and digital - is the diameter of the rear portion of the tool. Cone compound has the following form shown in the picture below.
Conical connectors for cartridges
Conical fastening method is more reliable, since it can withstand large power loads than the first embodiment of compound. In addition, it is easy to use: easy to remove and is also easy to attach to the shaft.
We find out a way to secure the cartridge
In order to figure out a way to secure the cartridge to the drill, it is necessary to conduct an external inspection. Experts at a glance determine the moment, and for inexperienced artists is marked by which one can judge the method of fixing the cartridge to the drill. Examples of labels for the tapered and threaded connections described above.
Remove the cartridges with their various connections + (Video)
To remove the cartridge, which is fastened a threaded connection on the instrument, perform the following steps:
1) Inside the cartridge there is a screw, located in the middle of the device. This screw has a left-hand thread.
2) For loosening screws need to use a screwdriver with Phillips tip.
3) it must be unscrewed in the direction of clockwise, that is to the left.
4) After unscrewing screws, which on some models drills may not be necessary to unscrewing of the unit serving for fixing an operating element. Unscrewing is carried out during rotation of the unit to the right.
To remove the cartridge was comfortable, recommended drill vise. If you can not carry out the unscrewing manually, you can use a pipe wrench or hammer, perform the procedures described in the section on removing a jammed drill bit.
Manufacturers of power tools such popular as "Interskol" and "Makita" have a similar structure to secure the cartridges drills and screwdrivers. Therefore, everything you need to unwind chuck - is to determine the type of connection and then use one or the other way to remove the cartridge.
Drill «Makita» with keyless chuck and threaded connection
To remove the cartridge from the tapered connection is often no problem at all. The easiest way is the possibility of carrying out the work, using a hammer. With the help of the component is carried out knocking out of engagement. Drill is necessary in this case to fix in a vice to chuck looked down. After that is a blow to the back of the cartridge, thus carrying out its dismantling.
Drill with various cones for fixing the cartridge
After the dismantling of the cartridge has been produced, it is necessary to change to a new one. To this end, the following actions are performed:
1) For compounds of the threaded chuck:
- made winding a new cartridge on the shaft of the screw in a clockwise direction;
- is carried out tightening a screw in the direction of counterclockwise rotation.
It is recommended to install the drum lubricate threaded connections.
2) To the conical compounds:
- with a hammer and mallet to install components into place.
So, to remove the cartridge from any drills need to know procedures and be able to distinguish between the structural features of the compounds. The only drawback of these procedures - is the need to replace the cartridge new, as worn parts, no longer be repaired.
How do I change the cartridge in the drills? How to work with a drill
The drill is an indispensable tool in the arsenal of DIY or professional. This equipment allows to drill holes of different thicknesses. There are several varieties of such tools. Today, there are both manual and electric drills. Each artist must know how to properly use a similar tool.
During continuous operation the equipment may malfunction. How do I change the cartridge in the drills, you should know before you start. In this case, even a novice will be able to repair your instrument properly.
Working with a drill assumes that the master carefully read the instruction manual of the instrument. This will prevent a lot of damage. You should also consider the type of tool. On sale today includes hand and electric drills. They may differ in size, capacity and additional capabilities.
Before working with a drill should be examined for the presence of the wall hidden in her column communications. It may be electrical wires or pipes. The metal detector will detect these objects. The hole will always be a little larger than the diameter of the drill. This should be considered when selecting fasteners.
It should see to it that the drilling (especially metal) drill from sliding. This is to avoid breakage. For ceramic surfaces it is recommended in place of drilling apply the patch. The drill must be positioned perpendicular to the wall.
There are several types of ammunition. This should be considered prior to the repair tool. The electric drill keyless chuck often used. They allow you to easily change drills in operation. Such kind of cartridge, for example, a power drill "Makita9raquo ;," Bosh9raquo ;, "Hitachi9raquo; and so on. d. It is not necessary to purchase a cheap model with such a device. They are easily damaged.
For impact drills jaw chucks are used. They are stable even under the hardest conditions. Adjustment of the drill is carried out in such systems with a special key.
There is also a third category of ammunition. This SDS-collet chucks. These two shank grooves are arranged. In this drill it screwed and fixed stop ball. Also in this cartridge has a groove 4. Two of them are needed to guide the wedges. Other two grooves perform a secure fit tooling. In such a spindle chuck is locked automatically after installation.
Considering the types of drills for patrons, not to mention their mountings. There are two main methods. Fastening may be performed by means of a threaded connection or a cone.
In the first embodiment, the shaft and the internal bore is threaded. It can be either metric or inch (depending on the manufacturer). To compound was durable special screw mounted inside the shaft. It has a left-hand thread. It spun clockwise.
In the second embodiment, fixation is used Morse taper. The end of the shaft has a characteristic shape. It is designed as a cone. Such a form has the same internal channel. It is at the end of the shaft is installed cartridge. This variant is more common in fixing the screwdriver.
Repairing a drill, it is possible to determine the type of attachment of the cartridge labeling. If the system has a threaded connection, the information will be applied to the body. Metric thread indicated "M9raquo letter ;. Digital, which contains the following letters mean diameter compound. It also indicates the maximum diameter of the drill chuck shank and its minimum value (e.g., 1-15 mm range). The latter figure, which is indicated on the labeling indicates the thread pitch.
For the inch system is used on the labeling designation UNF. Before proceeding to repair the equipment, you must carefully check whether the fixing of a new part installed by the manufacturer options. Virtually all international instruments inch system is used.
Cone labeled compound "V9raquo letter; and the figure (the size of the shaft). At this rate, when choosing new parts should also be sure to pay attention.
Repairing drill "Makita9raquo ;," Hitachi9raquo ;, "Stenli9raquo ;," Bosh9raquo ;, you should first read the manufacturer's instructions. This will help get the job done well. Holder shall hold the drill tightly. This makes it possible to drill holes with a certain accuracy.
Over time, the clamping mechanism of wear. This also applies to the landing place on the chuck shaft. He begins to beat. The working area when the equipment starts to oscillate. In this case, the hole is obtained with variations in diameter, and by location.
Wear mechanism does not allow tightly clamped in the drill chuck. It will stop when the load increases. To resolve these problems, it is necessary to replace the clamping mechanism.
Replacing a cartridge in the drill should be performed in accordance with the design type. To remove the fitting, you should use a screwdriver. With it unscrews the screw spindle. It is located inside the drill. The screw should be completely unscrewed and removed from the spindle. This element has left hand threads. Therefore, it should be unscrewed clockwise.
Chuck, on the contrary, has a right-hand thread. To remove it, you will need to unscrew the structural element counterclockwise.
Sometimes the screw is screwed very hard. Manually dismantle it can be quite difficult. In this case, it suffices to knock the screwdriver hammer when it is installed in a groove on the fastening element. You can also use gas or open-end wrench. The first of these should embrace the cartridge, and the second - to fix the spindle.
Difficulties with threaded cartridge replacement
Sometimes even the key for drill chuck can not help dismantle the tool design. In this case, you can use several other approaches. If the chuck clamping jaws are working, you can use a larger hexagon. This will help to make more efforts. Spanner in this case it is necessary to fix the spindle.
The construction of modern electric drill chuck does not involve the use of additional equipment. However, this does not mean that change chuck them will be easier. The clamping mechanism in this case is quite difficult to dismantle.
Sometimes it is necessary to disassemble the tool body. This will allow the spindle to reach hidden inside it. In the assembled form, this element may be hidden deep in the body. After removal and replacement cartridge design is going in reverse. You do not need to use additional keys.
If for some reason the screw inside the damaged, it can be replaced. In this case, it is recommended to purchase a cartridge adapter. It is sold for cam-type tool. Included with the supplied adapter and screw.
When considering how to change the cartridge to the drill, you should consider such a kind as conical clamping mechanism. In this case, the procedure is quite simple. In this case, you can use a special device. It is used for the removal of the bearings.
To release the clamping mechanism cone type drill pose vertically. Its drill should be directed downwards. Across the cartridge with a hammer to knock the surface. In this case, the clamping mechanism will gradually get out of his seat.
Conical connection then needs to be cleaned and sanded with fine sandpaper. After that, a new cartridge is easy to fall into place. It is fixed by tapping lightly on top of the hammer.
The causes of the problems with the clamping mechanism
Drill, instructions for use which master should be studied before use requires proper operation. In this case, it is able to avoid many problems.
Today, most electric versions of such equipment are equipped with SDS chuck type. It was designed by "Bosh9raquo ;. This device is not highly accurate. However, this mechanism allows to drill holes even in hard materials. In this case the tool operation is carried out with a punch. In this case, the accuracy of the drilling will not achieve. This is done using a special adapter.
If you need to drill precise holes in wood, metal, plastic, a special nozzle is used. Her release for quick-and for the jaw chuck.
Keep in mind that the drill can not make milling. In this case, the cartridge will not be able to withstand side load. It is also required to pay attention to proper selection of drill bits, grinding it, as well as marking the drilling center (with the help of the core).
Periodically, the tool is required to serve, change the old parts, lubricate moving parts. In this case also need to learn how to change the cartridge to the drill. Conical nozzle holder must deploy upward. His draped wooden spacers and are clamped in a vise.
Pipe wrench unscrew the nut and the bearing is dismantled. Pulled the puck. Further, the cartridge can get out of the rut. Manually Turn the adjustment sleeve. Cams need to get out of the guide.
After the dismantling of all the parts of the clamping mechanism is necessary to examine, worn parts should be replaced. Next, the mechanism is going in reverse. All moving parts are lubricated with grease.
Sometimes in the process of dismantling and other problems appear. For example, if a jammed drill chuck, it is necessary to disassemble the mechanism and make it a complete cleaning, lubrication. Especially such troubles appear after drilling the ceiling. Pollution pouring into the cartridge. In this case, it may become jammed.
If the cartridge flies need to increase the tension in the conical connection. For this mechanism to be heated up to 110 ° C in an oven. After that it is mounted on the cold seat. After this procedure, the cartridge will not fly.
It can also appear at the beating tool. It occurs due to the aging of the conical base or fracture uneven surfaces of the cams. In this case, the need to replace the old system of elements.
Let us consider how to change the cartridge to the drill, almost every artist will be able to repair the tool to continue the repair or construction work.
