How to tighten the cartridge on the drill correctly. DIY drill replacement

What are the cartridges for drills and how they are removed and disassembled on their own

Almost every master has at the disposal not only hammers, but also a drill for drilling holes in wood, metal and even concrete. To work with this tool, the design provides for a special clamping mechanism. This mechanism is also called an executive organ or a cartridge for a drill that is different. Drilling tools are equipped with such a device, but when you fail, you will need to dismantle, repair or replace it, which will be discussed in the material.

When choosing a cartridge for a drill, the buyer is interested in the question of what diameter the drill can be squeezed in the lips of this device. That is why many buy cartridges in which the shanks of the working nozzles are clamped by the parameter (size of the muzzle). In addition to the maximum diameter of the drills, you must also know that the devices differ in design and type of seat. To begin with, we find out that the cartridges for drills are classified in appearance into two main types:

  • Key-this is their folk name, and in the scientific they are called gear-cage, which is associated with the mechanism of their functioning. This is a popular version of clamping mechanisms for drills, characterized by high reliability indicators
  • Quickly jokes or BZP. differ from key ones in that they do not need to use a special key that compress the sponges of the device

Tough-cage cartridges from fast-and-packed are highly reliable. The very first prototypes were used on hand drifts, which have similarities with key and quickly and quickly ascense. The principle of operation of the simplest cartridge from the old hand drill is as follows:

  • To fix the nozzle in the device, it is necessary to hold the handle and twist the clamping coupling or sleeve
  • Install the nozzle of the tail inward
  • Twist the clamping coupling to the stop, and then additionally use a chisel or breakdown with a hammer for a more reliable fixation of the nozzle

Fixation with a chisel is needed so that there is no nozzle during operation. Such cartridges had many shortcomings, so the advanced models soon appeared. key. Unlike the first types of cartridges, key ones do not require the use of a chisel and a hammer for a clip of a shank nozzle, as they are replaced by a special key with teeth. In addition, the carving of the clamping coupling was quickly covered with corrosion, so there were difficulties with its twisting. Today, old types of equipment are found only on manual old droplets, and are practically not used on power tools.

It is interesting! Why outdated models of cartridges have much in common with modern key and fast.packed devices? All of them have the same principle of operation based on the movement of fists. These fists are also called lips or tsangs, from where the names of Tsang and fist cartridges appeared.

The design and advantages of fast.and.recessive and key executive bodies

Cartridges on the drill are cone.shaped devices, the main purpose of which is to transfer rotational actions from the gear shaft to the working nozzle. The principle of operation of modern executive mechanisms is simple and uncomplicated, and it is based on the movement of movable sponges. The movement of the sponges occurs due to the thread. Figs with threads move through the sleeve, due to which there is a nomination or vice versa. There are three fists in the cartridge design, which are located in a circle at the same distance from each other. This method of clamping of nozzles is considered one of the most reliable and effective. 4 fists are used on mini-fists. To find out the pros and cons, consider the features of the types of cartridges for drills.

  • Popularly and self.loading cartridges are popular, which do not require the use of a special key. The devices under consideration are one.button Idwuhmuft. One.way devices are less reliable, and they are more difficult to disassemble, unlike two.litter. Two.litter consists of two elements, which simplifies their use. For the clip of the nozzle, it is necessary to hold the lower part of the cartridge (skirt) with your hand, and the second tighten or twist the clamping clip
  • Key cartridges have high reliability, which is associated with the application for the clip of nozzle through a special mechanism and key. The principle of operation of key cartridges is the same with fast.packed, and they differ only by the method of acting moving sponges

Knowing the varieties and the differences between the devices for the drills, we will deal with their advantages and disadvantages. The advantages of fast.packed devices include:

  • There is no need to use additional tools
  • The ability to fix the nozzle with one hand
  • High speed of replacing nozzles
  • Aesthetic appearance. This is a slight advantage, however, a drill or an electric screwdriver with this type of equipment looks more modern

Before buying a cartridge for a self.loading drill, you should deal with their shortcomings:

  • Low reliability. This is due to the manual way to clamp the nozzles. The sponges are not able to tightly squeeze the tails of nozzles, so when jamming, the drill will turn inside the cams
  • Quick wear. the more often the drill jams, the faster the mechanism wears out
  • The need to take into account the size of the hole for fixing the nozzles with the corresponding diameters of the shanks. The models are common in which you can fix drill with tailings up to 10 mm. Models of 12 mm and 13 mm drill are also produced, but they are less common

Based on the above advantages and disadvantages, it can be concluded that the use of rapidly and two.luminous cartridges is rationally on low.power power tools, such as gayworms, screwdrivers. The use of them on drifts is irrational, unless this tool is used to screw screws and screws. The most important advantage of the BZP is that they allow you to quickly replace the nozzles during operation.

Why all drills from the plant are equipped with key.type cartridges with a zangia mechanism? Few people think about it, and the answer to this question is simple. Key elements provide a high degree of reliability of fixing the nozzle. Even if the drill jams, then with a low probability it will turn into the mechanism. That is why all the electrodeus are equipped with safety couplings, excluding the likelihood of tearing the tool from the hands, as well as prevent engine burning at high loads.

The advantages of key executive bodies include:

  • Reliability-it is precisely due to the high degree of this indicator, the gear-cage elements are still used
  • A high degree of wear resistance. if the BZP is protected by a plastic cover that wear out quickly, then the key elements are made only of steel, so the probability of their external damage is excluded. If the key.type cangy cartridges wear out, then only because of the failure of the movable sponges and springs

Although the second type of device has fewer advantages, however, these cartridges should be chosen for drills. Many people prefer to use them in screwdrivers. Of the shortcomings, only the need to use a special key should be noted. If this key is lost, then it will not work to extract the nozzle. It will be difficult to make a new key with your own hands, but it can be bought, since they are sold not only in tandem with a new equipment, but also separately.

It is interesting! When comparing prices, we can say that key devices for drills are more expensive than fast.sounding.

Types of cartridges

The clamping devices of screwdrivers are divided into:

The difference lies mainly in the fact that self.loading models fix products automatically.

If the tool has a lock, you can use one.way cylinders.

In the absence of a lock, you will have to use a two.button type.

tighten, cartridge, drill, correctly

Elements with one coupling can be clamped with one hand.

To work with another type, the participation of both hands is required.

Quick and self-loading models are intended mainly for modern tools.

It is convenient to use models with automatic clamps to those who have to quickly and often change various nozzles.

tighten, cartridge, drill, correctly

Key options are less convenient, but more reliable. They are better clamped and more resistant to shock loads.

If the cylinder is used in intensive mode, it is recommended to choose an electric screwdriver with a key.

Types of cartridges

Industrial companies have mastered several types of cartridges used for their screwdrivers, some interchangeable, others are strictly individual. Each species has a number of advantages, but not one is deprived and shortcomings. Perhaps that is why the unified universal type of product has not yet been developed that would satisfy the desires of consumers and the capabilities of manufacturers.

The rapidly packed cartridge has a simplicity of the design: a steel sleeve is installed on the steel spindle with a corrugated steel for ease of holding it with a hand with a surface. For tightening, you do not need a special, requiring constant attention, key. This is one of the most reliable and wear.resistant types of cartridge, but it also becomes unusable with active operation over time. The drill with a round shank is becoming increasingly difficult to tighten, they begin to turn. Over time, the fists holding the drill are triggered. It is better to just replace the product.

Self.loading cartridge also does not require a special key. This is one of the most technically advanced cartridges. It does not need to use muscle strength to tighten it. Simple turning of a mobile coupling sufficiently. On some models of screwdrivers, cartridges with one coupling are used. On others with two rotary couplings. This type of cartridge is most convenient with a frequent change of working nozzles, for example, when drilling alternates with twisting self.tapping screws and you have to quickly rearrange the drill and batter. The main details of the case of this cartridge are made of instrumental steel, and the outer parts of the plastic.

A cartridge with a hexagonal shank (hexagon). As can be seen from the name, the shank of this product has a hexagonal shape. Such a cartridge also does not require a special key. This type of node is widespread on mini-fires and for special engraving machines used in the manufacture of jewelry and in bone-resistant production. Also for mini-fires and drill, special zang cartridges are used. With the help of such micro.instruments, holes are drilled to install electronic boards.

We extract a drill from a jammed cartridge

If you are faced with the problem of jamming the drill, then not in all cases to extract it requires dismantling the cartridge. When the drill jammed in the cartridge, then it can be removed by applying a vice.

The drill must be squeezed in a horizontal position. The drill housing must also be fixed so that it is motionless. On the surface of the cartridge and sleeve, you must tap first lightly with a hammer, and then strike strong blows. It is important to apply a sleeve in the direction of the tangent plane. Work with a hammer continues until the drill is released from the engagement with the cartridge.

If with the help of a hammer it is not possible to release the drill and promote fists, then you can use the gas key. The drill housing and the jammed drill is fixed in a vice, and a gas or pipe key is carried out by the cartridge in the direction of the time of the time. You can also use two pipe keys, with one tool, squeezing the rampart of the drill, and the second try to scroll through the clamping element.

Fastenings: what are they

The clamping mechanism is attached to the drill shaft using the following methods:

In the design of the threaded connection, an additional stopped screw shown in the photo below is often used. With it, the reliability of fixation of the cartridge is ensured.

Cartridge, key and stopped screw for threaded connection

The threaded connection is provided through identical threads on the shaft of the tool and in the channel of the clamping mechanism. The type of thread used in this compound plays considerable importance, and they are metric and inch. The used thread on the drill is indicated using a special abbreviation, which has an approximate look:

Designation Decoding
1.5-15 The first digits of the abbreviation indicate the minimum and maximum diameter of the drills, which can be used to squeeze this cartridge
M13 The letter designation indicates the use of a metric type of thread, and the number “13” is its diameter in mm
1.2 Designation of thread step in mm

If an inch thread marking is used in the tool, then the abbreviation is indicated by UNF. In modern drift models, an inch type of thread is used, since the choice of clamping mechanisms with an inch carvings is much more extensive.

The shaft for the reliability of fixing the clamping mechanism is equipped with a locking screw, on which there is a thread with left.sided cutting. Therefore, the screw is removed to remove the cartridge in the direction of the time stroke.

A less common way is to fasten the cartridge using a clamping mechanism based on the use of a cone cone. In this case, the shaft is the shape of the cone, and the clamping mechanism is equipped with a similar form in the internal channel. The mechanism is mounted under the influence of power planting on the design of the tool shaft of the tool. Such mechanisms are marked using the following abbreviations: B10, B12, B18 and T.D.

Key cartridge for a drill with a conical connection (marking)

The letter designation indicates the labeling of the cone, and the digital one is the diameter of the tail of the tool. The conical connection has the following view presented in the photo below.

The conical mounting method is more reliable, as it withstands large power loads than the first connection option. In addition, it is easy to use: it is easily removed and is also easily dressed on the shaft.

Find out the method of fixing the cartridge

In order to find out the method of fixing the cartridge on the drill, it is necessary to conduct an external inspection. Specialists at first glance determine the moment, and for inexperienced masters there is a marking by which you can judge the method of fixing the cartridge on the drill. Examples of marks for conical and threaded joints are described above.

In this article, we will analyze the PPPOE settings on Mikrotik, this protocol provides extensive users, networks and accounting control. Currently, it is mainly used by providers to control clients on XDSL and cable modems, as well as in ordinary Ethernet networks. Is the expansion of the standard PPP protocol. The difference between them is the transport method, PPPOE uses Ethernet instead of a consistent modem connection.

Simply put, PPPOE is used to issue IP addresses to customers based on the authentication by login and password instead of workstations, whose authenticity is checked at a static address or DHCP. It is not recommended to use a static IP address or DHCP on the same PPPOe integrations from obvious security reasons. Client and server work at the second level Ethernet.

How to disassemble a cartridge on a drill

Dismantling the device is necessary in order to extend the service life of the product. In the process of disassembly, cleaning and lubrication of products. Dismantling can be carried out as follows:

  • We use a peorator with a special adapter on which a fist cartridge with a threaded connection is put on.
  • Fists should be hidden inside.
  • A sheet of foam or polystyrene foam is applied from the end part of the device. After that, the back of the foam should be rested at the wall.
  • The peorater is launched in impact mode. Within 2-3 seconds, the cartridge will be disassembled.

The video describes the disassembly process in more detail. The video also presents the process of reverse assembly. There are many other disassembly options, but the simplest and most acceptable is the one that is described above.

At the end, it should be emphasized that if you want to extend the service life of your tools, be sure to allocate time for diagnostic procedures.

Installation of a cartridge

Installation is in the reverse order. In the case of threaded fixation, you first need to wind the cartridge case onto the thread. Then screw the control screw. Before that, it is advisable to drip a little sealant on it. For additional fixation.

Installation of a clamping cartridge on a cone Morse, simple and uncomplicated.

You need to insert the cone into the nest and sharply hit it. After planting, check the fixation. In the future, when working, the cone will settle even more.

Existing types of fastening

The cartridge on the shaft of any drill, electrical screwdriver or a pedorator is attached in two ways. using a threaded connection or on a cone. A variety of threaded connection is the use of an additional locking screw.

The threaded mount implies that an identical thread is made on the shaft of the drill and on the inner channel. metric or inch. Therefore, in this case, during the repair, the question is raised how to unscrew the cartridge. Type of thread and its main parameters are marked on the case. For example, the designation is knocked out on the housing 1.5-15m13x1.2, which means the following:

The principle of removal of a drill cartridge.

If an inch thread is used, then the designation is introduced, and the diameter is indicated in inches (for example, 1/2). When replacing the cartridge, it is necessary to check the compliance of the marking of the mounting size. Modern drills mainly have an inch thread, which meets international standards and expands the possibilities of interchangeability.

For the reliability of mounting on the shaft, a stop screw is installed inside the device. This screw has a left thread, t.e. In order to unscrew it, you need to twist clockwise.

The second method of attaching the cartridge on the shaft of the drill is based on the use of the Morse cone cone. In this case, the end of the engine shaft is made in the form of a cone. A similar conical part has an internal channel from the lower end. The cartridge is simply planted with force on the shaft cone. The marking of such elements has several meanings: B10, B12, B16 and B18, where B means the use of the Morse cone, and the numbers are the maximum diameter of the shank of the drill, which can be fixed in this cartridge. This method of fastening is quite common, especially in screwdrivers.

Preparation for work

Before starting work, appropriate preparation should be carried out. To determine the readiness of the tool to perform tasks, there are several conditions:

  • When the drill starts using the power cord, it must be connected to the network;
  • If it operates using the battery, then it must be connected and charged;
  • A drill is inserted and recorded inside the drill.

To check the operability of the drill, you need to click on the power on the power supply key. If the cartridge rotates fast enough, then the charge is enough, and you can start work. If it rotates very slowly, then the battery is discharged and it should be recharged.

How to remove and change the cartridge for drill

In electrical drills, a special device is used for reliable fixation of the Soverol, which is called a clamping cartridge. In household drifts, fist cartridges are most widely used. With intensive use, they can fail and require replacement or repair. During these operations, problems often arise. In the article, the master plumber will tell you how to remove and change the cartridge for a drill.

The cartridge serves as a landing place, the holder of the main working element of the drill, an electric screwdriver or a penetrator. This can be not only a drill, but also a drill on concrete for tools with a shock function, a special nozzle in the form of a cross.line screwdriver. There are special nozzles for a drill designed for grinding, cleaning various surfaces. They are mounted on a rounded or multifaceted pin, which is also installed in the cartridge.

Cartridges for drills are different in design and the method of installation on the tool and are divided into three types:

Was invented back in 1864 by American engineer Stephen Morse, who also developed and proposed the use of a spiral drill. The peculiarity of such a cartridge is that the clamp of the working element occurs due to the mating of two gross surveys and a separate part with the landing hole. The shaft surfaces and a hole for installing the drill have equivalent dimensions of the cone, the angle of which ranges from 1 ° 25’43 ” to 1 ° 30’26 ”.

The angle is adjusted by turning the base of the mechanism, depending on the thickness of the installed element.

A more common type of cartridge on manual power tools for home use. The principle of the device of such a cartridge is simple. at the end of the pin leaving the pin, the thread is cut, and the cartridge is wound on it like a nut.

The drill is held in the cartridge due to three cone.shaped petals located in the center of the cartridge in Tsang. When the tsang nut is turning on a special key, the petals converge together and clamp the shank of the drill or other working element. a corolla for a mixer, nozzle for a screwdriver, shock, tap.

It is considered the most convenient option. This is the latest in the time of the invention technological modification of this device. It is used in almost all modern models of well.known drift manufacturers.

The working cutting or other element is also fixed due to special petals, only for their clamping the key is not required. The fixing petals are clamped with the hands. turning the adjusting sleeve, on which a corrugation is applied for the convenience of scrolling.

So that the sleeve does not untwist during the operation of the tool, it provides for an additional block.

Since all types of cartridges for drones have their own structural features, their dismantling provides for various actions. You will need special tools.

It is possible to dismantle both improvised or interchangeable means, but at first disassembly it is not recommended to experiment, as you can damage the tool.

In general, the procedure does not represent anything complicated and quite perfectly at home.

The method of fastening the cartridge by Morze is one of the most reliable, but does not provide for complex manipulations. The design perfectly withstands power loads along the axis both in conventional drifts and in tools with shock function. Therefore, it is so widespread in production enterprises.

The cartridge is dismantled in several ways.

It is necessary to strike with a hammer from below on the body of the cartridge. The main thing is that the blow is directed along the axis towards the place of landing of the cutting element. drill.

Disconnect the cartridge, wedging the surfaces: insert into the gap between the cartridge and the drill housing, for example, the chisel and, breaking it with a hammer, carefully remove the shaft. At the same time, it is very important not to beat in one place so that there is no bias of the shaft: gradually putting forward the shaft of the cartridge, the chisel must be inserted into different places.

Use a special puller, like those used to dismantle bearings.

In most hand drifts with conical cartridges, the shaft bearing is mounted inside the tool body. But there are also models where it is located outside. In this case, the removal should be done as carefully as possible, otherwise there is a probability of damaging the bearing. If the shaft seized too much and does not lend itself to removal, do not beat with a hammer on it with all its strength.

In these cases, it is recommended to try to treat the surface with anti-corrosion agents-kerosene, aerosol drug WD-40.

The gear-cage cartridge is wound on a pin built into the drill. Accordingly, to dismantle the device, you just need to be unscrewed in the opposite direction, but some nuances should be taken into account. The peculiarity of the threaded attachment of the cartridge is that on the pier leaving the drill, the thread is right.sided, and on the cartridge itself. left.handed. Thus, during the operation of the tool, the cartridge, turning clockwise, is automatically wound and tightened on the shaft.

This feature guarantees its reliable fixation on a drill, excludes backlash and spontaneous discharge of the element from vibration. This specifics of planting the cartridge should be taken into account when it is removed. during the operation of the drill, the cartridge is wound on the axis until it stops, the thread is clamped with maximum force.

Work for work

The replacement of the drill cartridge is easily produced if you know the design of this node and the methods for its fastening. For repairs, you will need a simple set of tools:

  • Locker vice, you can use not standard, but a reduced option for home needs;
  • a steel hammer;
  • carpentry kiyanka;
  • pliers or pliers;
  • medium.sized tubular key;
  • set of wrenches;
  • calipers;
  • screwdriver;
  • file;
  • sandpaper.

The list indicates a minimum set, there are situations when other locksmithing devices may be required.

How to open a drill cartridge?

The purpose of the cartridge on the drill is a reliable fastening of the drill or other nozzles (construction mixer, grinding circle, etc. D.). Fixation is carried out by three mechanical “fingers”, which are reduced and divorced using a threaded mechanism.

There are two main varieties of cartridge:

  • A non.closing variety. To open such a design, it is enough to grab the body with your fingers and, turning on the reverse rotation, briefly press the trigger of the tool. The drill itself will test the shaft, diluting the “fingers” fixing the drill. Such a cartridge is easier in work, but the reliability of fixing the tool will be slightly lower.
  • A variety equipped with a key. The key is a T-shaped device, at one end of which a conical gear-shaped gear is placed. Two other ends serve as a handle for rotation. To promote or tighten the cartridge, the key is inserted into the hole on the body and rotated, holding the body with the other hand.

As a rule, the key is included in the supply of power tools. It either lies in the box or attached to the power cord with a special mount.

Dismantling of a threaded cartridge

To remove it, you need a screwdriver. She turns a screw screwed into the tool spindle and installed inside the product. After which it is twisted from the spindle. As mentioned above, the inner screw is distinguished by left thread, therefore, it spins clockwise. True, the cartridge is unscrewed counterclockwise, since it, on the contrary, has the right carving.

tighten, cartridge, drill, correctly

If the screw does not want to unscrew, knock on it through the screwdriver with a hammer. Difficulties with a cartridge should not arise, it is easily twisted. Although when difficulties appear, you can use a wretched face and gas keys. The first to fasten the spindle to the drill, and the last to clamp the cartridge.

In addition, when clamping fists function in the cartridge, you can install a thicker hexagon for its twisting. You also need to fix the spindle with an ore key. On most modern drones operating from the battery, additional devices are not required to attach a drill for a drill. However, changing the cartridge to them is very difficult.

When and this does not help to remove it, the tool body is versed. Thus, it is possible to reach the spindle, because in the collected form it is hidden. Then everything is going back, but without using the keys.

What to do if in the process of replacement spoiled the inner screw? In this situation, it is better to purchase an adapter for a cartridge for a fist type peorator, since a screw is included with it with it.

How to replace a conical copy?

Difficulties when extracting an element mounted on a shaft cone should not appear. You can use a special device that is used to replace bearings.

But the easiest way is to put the tool vertically, while the drill will look down. Then you need to tap carefully over the entire surface with a hammer, until the cartridge knocks out of the cloth. If necessary, grinding it. The new part is inserted with light blows from above.

Characterization of a rapidly packed drill cartridge

The standard fast.packed cartridge has not a too complex design. Tightening and weakening will consume the use of a special metal sleeve having a rolling or rifting. Quite often for this purpose, a plastic sleeve with ribs is used.

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

How to remove and disassemble the cartridge electrode

Even small, insignificant repairs will require the correct disassembly of the structure. To date, there are only two mechanisms for mounting on a working shaft, so the process of doing dismantling can vary.

With a threaded method, mounting the design must be disassembled in the following order:

  • to deepen the fists into the housing and dilute them as much as possible;
  • Perform a fixing screw located in the central bottom of the device. Fasteners with left thread need to be twisted clockwise;
  • With the help of an an ore key on the shaft, the device is unscrewed.
tighten, cartridge, drill, correctly

The most popular and often used in modern tool is a conical connection. In addition to the exceptional strength of the conical connection, this option with the right approach can be easily disconnected quite easily. For this purpose, the gear is performed in a circle, after which the element is knocked down from the shaft using a sharp and accurate blow to the back of the shaft.

After the cartridge is removed, it is necessary to correctly determine the type of malfunction. You can independently carry out repairs in the absence of significant damage to the parts and jamming caused by metal chips that got inside adjacent parts. As a rule, to restore working capacity with this variant of breakage allows washing elements in oil or kerosene using a soft medium.sized hand. After this method of cleaning, assembly is made in the reverse order.

Most often, the owners of the actively used tool are faced with a number of malfunctions caused by wear, as well as damage, which have undergone threaded or gears. Minor local damage to this type of type are easily eliminated by grinding. For this purpose, it is recommended to use a file or standard grinding skin. In the most difficult cases of breakdowns, the complete replacement of the failed cartridge is most often required.
