How to remove a cartridge from a drill

In most portable drills, cartridges are twisted on a threaded spindle, which is connected to the drill, and then retained in place with a stop screw. To understand which element must be bought to replace the old, it is necessary to open the petals to the widest point and look into the base with the flashlight

If a screw is visible in the lower part of the cartridge, you should pay attention to the type of head. If it is absent, then this is probably a conical spindle

When buying, it is also worth considering that the element is obliged to ensure the proper rigidity of the fastening, taking into account the number of revolutions. expensive models allow reducing radial beating.

Not in the last place and the convenience of using the cartridge, in this case, quickly ascended in the first position, but when it comes to durability, it is better to buy with the key.

If drills made of carbide material are used, then the cartridge should be self.center, since such equipment has poor resistance to longitudinal bending

It is important to know that the rigidity of the fastening is always compared with the length of the nozzle and the material from which it is made

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.

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.

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.

The maximum diameter of the shank drill

This size shows how widely the clamping lips of the cartridge are revealed.

According to this parameter, cartridges for drones may have the following maximum sizes:

At the same time, the first three sizes are very rare. The remaining diameters are much more common.

It is easy to guess that the manufacturer selects the maximum clamping diameter of the shank for a particular drill based on its power and dimensions. It would be ridiculous to install a 16 mm cartridge on a small drill of 300 watts, as well as for a kilowet model of a 10 mm cartridge. Although this is quite possible to do this, since, for example, there are kilowet drills with a 1/2 ″ landing place, where the cartridge with a clamp for 16 mm is initially standing, and there are also 10 mm cartridges with the same landing. Well, and the landings will be discussed below in the corresponding section.

Regarding the maximum diameter of the clamp, then this question begins to disturb the user, if he fails to squeeze the larger nozzle or drill in diameter, which allows its drill model. Well, in such a situation you can choose the right cartridge, but you should not get carried away with a lot of work with a large diameter planting, since most likely your drill is not intended for working with it due to low power.

Sooner or later, with each master, such as the loss of a clamping key for a drill cartridge. How to be in such a situation when an important tool is not at hand, and the labor event can not be left. Fortunately, there is a very effective way to tighten and release the drill, without using a specially designed device for this.

Drill chuck disassembly

In order to tighten and release a drill cartridge without a clamping key, it is necessary to arm yourself with another drill or a suitable metal rod in size (the diameter can be slightly smaller). Also for the operation you will need a reliable screwdriver with a straight slot. It will be used as a clamping lever.

Useful advice: experienced craftsmen attach the key for the cartridge on the insult for the wire. Thus it will always be at hand and will never be lost.

So, the drill (or rod) is inserted into the available hole and holds the hand. Meanwhile, the screwdriver, resting on the drill, begins to gradually tighten (or loosen) the cartridge. For normal fixation, the average effort of hands should be enough. After the procedure is completed, you need to check the reliability of the clamp without fail.

Interesting fact: experienced places know how to tighten and release the drill with their bare hands. To do this, they take the tool with a cartridge from themselves, after which the palm of the left hand is abruptly hit from top to bottom down the cartridge. If the first time does not work, the procedure is repeated again. After such ingenuous fraud, the cartridge is delayed and released manually.

In order to disassemble the cartridge, you still need to insert the already clamped drill into a hole for a start, then completely immobilize and repeat all the actions with a screwdriver.

The maximum diameter of the drill

This size shows how widely open the cartridge sponges.

According to this parameter, drill cartridges may have the following maximum sizes:

At the same time, the first three sizes are very rare. Other diameters are much more common.

It is easy to guess that the manufacturer selects the maximum clamping diameter of the shank for a particular drill, based on its power and size. It would be ridiculous to install a 16-mm cartridge on a small drill with a capacity of 300 W and a 10-mm cartridge per kilowatt model. Although, this is quite possible, because, for example, there is a drill for a 1/2 inch saddle, where at first there is a cartridge with a clamp of 16 mm and 10 mm cartridges with the same landing. Well, landing will be discussed later in the corresponding section.

As for the maximum diameter of the clamp, this question begins to disturb the user if he cannot block the nozzle or a larger drill than his drill model allows. It is good that in such a situation you can choose the right cartridge, but you should not do a lot of work with a large diameter planting, because, most likely, your seeder is not designed to work with it due to low power.

Sooner or later, the following problems affect all users of the seeders:

In the first and second points, it will be interesting if necessary to use drills or nozzles of different diameters. And the third. When you need to replace the cartridge.

This article clearly explains all sizes of cartridges for drilling to help users understand these problems. Please note that all of the above equally refers to keys and keys.

As for the maximum diameter of the clamp, this question begins to disturb the user if he cannot block the nozzle or a larger drill than his drill model allows. It is good that in such a situation you can choose the right cartridge, but you should not do a lot of work with a large diameter planting, because, most likely, your seeder is not designed to work with it due to low power.

The minimum diameter of the drill

Cartridges with a minimum clip diameter have the following sizes:

  • Size 0.5 mm. on cartridges with a maximum clamp up to 6.5 mm;
  • 0.8 mm. up to 10 mm;
  • 1 mm. up to 6, 10 and 13 mm;
  • 1.5 mm. up to 10 and 13 mm;
  • 2 mm. up to 13 mm;
  • 3 mm. up to 16 mm.

Here the user has a need opposite to the one that was mentioned in the previous section. That is, you have a cartridge that clamps the drill and nozzle with a shank, for example, 2 mm, and you need to clamp the shank for 1 mm.

Again, the problem is solved. The only thing to work with a large and heavy drill with a small diameter drill may be inconvenient. It is easy to break. Well, it is worth noting that the dimensions are 0.5 and 0.8 mm is also not easy to find.

seat

Can be threaded or conical. Most modern models use threaded connection. However, sometimes it can be conical. Mostly on drills with a cartridge with a maximum shank 16 mm.

The thread can be metric, but in most cases it is inch on modern drills. Manufacturers always write directly to the cartridge, what is its thread, if it, of course, is cut.

Inch thread is available in the following sizes:

Cartridge with a marked thread 1.5. 13 mm. 1/2

The most common are 3/8 and 1/2. These two devices can be used on cartridges with max. Saar 10 and 13 mm. Landing 1/2 is rare, but still found on cartridges with a clamp up to 16 mm. 1/4. Planting on cartridges up to 6.5 mm, and 5/8. Again up to 16.

Metric thread only m12. Used for cartridges with a clamp up to 10, 13 and 16 mm.

The conical seat may have a marking B12, B16 and B18. The numbers indicate the diameter in millimeters. They are used on cartridges with clamps up to 10, 13 and 16 mm. And with the last diameter most often.

Types of cartridges for drill

Any electrical or manual drill has a cartridge for fixing a shift tool. By the type of installation to the drill itself, there are such main types of cartridges:

Installed by bluhing on the thread on the cartridge. Thread (its type and diameter) are indicated by the methods of casting and machining. Is available for a certain interval of the working diameters of the shank.

Installed by elementary planting on a special element of conical shape. From the threaded differs the letter “B”. Remove it optimally by knocking out. Fixing a shift tool. most often with a rapidly collapsible method.

Conical cartridge for a drill

Most often, the method is involved in the power tool of a professional level. The reason is the qualitative level of attachment of the cartridge.

choose, drill, cartridge

As for the methods of direct consolidation of the replaced tool, the types of cartridges on this basis are given further.

Key

One of the most popular cartridges for drills, mostly electric with slight power.

Key cartridge

The main feature is the high reliability of fixing the shift tool. Replacement is performed with the tool disconnected with two hands. In order to unscrew the nozzle (drill or another, on the shank), the key is required.

It is a lever with a part of a unique shape for interaction with the cartridge. Being fixed in the hole and getting rotation, it shifts the lower part of the cartridge. In this case, the compression efforts on the Tsangs are removed, the nozzle falls. In which direction to twist the key, often everyone forgets: for unscrewing it should be rotated clockwise.

The scope of use is expanded to shock drills. Due to the absence of turning the drill, the workflow will not stop unexpectedly.

The interchangeability of keys works on the versatility of the power tool. Popular solution: attach this item with a regular electrical tape to the power cord.

Quickly sound

One of the most common drill type is a fast.packed cartridge. It is widely used for the production of electric drifts and peorators.

Fasted cartridge

Intended for the fastest replacement of a shift tool. It’s easy to change it, this does not require a key. It is only required to hold the upper (end) part and unscrew it in the right direction. Before work, it is recommended to study the instructions. there are models with left thread.

There are cartridges with 1 and 2 couplings. In two.differently, you will have to hold the nozzle with both hands, so the replacement may be uncomfortable. The electric tool allows you to some extent to call the cartridge as selfless. In this case, the upper part with the nozzle is held with one hand. The second supplies power to the electric motor, which slowly rotates the shaft.

Cangy cartridge

The cangy type of cartridge is used for machines processing metal cutting. Cutting tool fixation is automatically performed. Limitedly involved for a mini drill.

Cangy cartridge

Basic application: accurate operations on the machines turning, drilling, milling. You can install in it both a cutting interchangeable nozzle and a processed billet of a cylindrical shape. Due to the quick opportunity to change the cartridge for drills it is optimal for its use for a drill or a CNC machine.

The principle of operation is as follows. Design: Tsangi (flat or voluminous clamping parts) and nut. When moving the nuts, the zangi is compressed, centered an inserted object and hold it. A cartridge with a lot of tsng works better. There are variations with three, four, six or more tsangs-jackets. Each of them is designed for the harvesting of a certain diameter.

Unscrewing such a tool is not difficult.

Mini cartridge for drill

A mini-patron for a drill is installed on a small drilling machine.

Mini cartridge for drill

The main category of users are electronic workers, jewelers and engravers, door and accurate workmers. The main possibility of this variety of tools: Work with the diameter of the tail of the cutting tool to a fraction of a millimeter.

The speed of rotation is almost not limited, at the level of tens of thousands. Mass. up to tens of grams. Change it is simple. actions are similar in that they are performed for more overall types.

For newbies

So, let’s start in the most simple case. with inexperienced users. Screwdrivers have such a thing as a torque regulator. It looks like a scale around the front by an electric screwdriver, which immediately behind the cartridge. It applied numbers from 1 to 10, 15, 20 or even more. in different models in different ways. and the last position on it is indicated as a drill. If you rotate this regulator and install it opposite a special mark so that there is one of the numbers next to it, then when a certain torque is reached, the cartridge will not rotate further, but it will begin to fade. If you put on a “drill”, then the electric screwdriver will try to twist with all his might, how much engine power allows it.

True, it is worth noting that in two.speed screwdrivers at the second speed even in the “drill” position, if the torque reaches a certain value, then a protective system is triggered, which simply turns off the current supply. At the first speed, the electric screwdriver will also try to twist “to the last”.

And the beginner can start drilling or wrapping screws, for example, when the regulator of the moment is on one of the numbers, or an electric screwdriver is at the second speed (and it is recommended to drill on it).

The drill can squeeze quite strongly, and as a result, when you begin to free the drill or bat in the standard way (turning on the reverse, holding the cartridge and by pressing the start button), may just work either a torque limiter or a protective system.

Therefore, in such a situation, you just need to put an electric screwdriver at the first speed and the regulator of the moment put to the “drill” position. On single.speed models, it is enough to only install the regulator of the moment on the position of the “drill”. Well, then again we get out in the standard way.
