Modern drills use two main types of chucks that differ in how the drill is fixed. The first type includes key cartridges. This design allows you to fix the drill with a special key that rotates the adjusting ring in a clockwise direction until the element is completely fixed. The second type includes keyless chucks. The design allows the replacement and fixation of drills manually. This is very convenient when you need to change the nozzle frequently. However, there are situations when there are difficulties with changing the drill in the chuck. In this case, a few useful recommendations will not interfere with how to pull the drill out of the drill without a key. We will talk about this later.

Reasons for difficulties in replacement

Sometimes there are situations in which it is not possible to remove the drill from the chuck in the usual way. Such difficulties may have various causes. Mostcases this is due to the device of the drill, when there is no restrictive mechanism in the cartridges that insures the surface from excessive force applied at the moment of clamping. This causes the chuck to jam when the adjusting ring cannot be reversed. As a result, it turns out that the drill is stuck in the drill. How to get it out? Let's give some recommendations.

A similar situation can occur when the drill is skewed in the chuck. This cause is more likely to occur when using a small diameter tool. These elementary reasons can be avoided with a careful attitude to work. In other cases, you must follow some rules when removing the drill with the tool at hand.

Marriage

Using drills made of soft metal may cause chips to form inside the chuck. It often falls between the jaws of the clamping mechanism and works as a stopper. Such an obstacle is capable of holding the jaws of the chuck when trying to loosen the clamping force. Also, the danger is a deep subsidence of a soft drill into a chuck, its base can flatten and lock the locking elements. It is especially difficult to remove such a drill when it has broken at the level of the fasteners. This makes it impossible to clamp it in a vice. How to pull the drill out of the drill in this case, we will learn further.

Violations of work rules

Safe drilling mode involves following certain rules, the neglect of which can lead to injury or damage to the tool. Patron in greatest dangerdrills, taking on the main load in contact with the surface. To avoid unpleasant consequences, it is not recommended to sharply change the angle of inclination of the drilling. It is also necessary to limit the applied force on the drill, the drill of which is in the process of drilling. Excessive load may cause the drill to break or jam in the chuck. For machining heavy-duty surfaces, you must use drills designed for such work.

Chuck failure

A drill chuck, like any other mechanism, is subject to wear and tear and may fail over time. Also, the cause of jamming of the cartridge can be a factory defect. The spring in the device of the blocking mechanism can also break, as a result, the regulating element will no longer be released after pressing the button. The standard drill chuck is designed for long-term use, subject to proper use and periodic maintenance. However, if it fails as a result of component wear, it is better to replace it with a new one.

Regular extraction method

The technique of how to pull a drill out of a drill under normal conditions looks very simple. The cams of the mechanism holding the drill are bred by rotating the adjusting sleeve manually or by turning the key in the opposite direction to the clockwise direction. After this procedure, the drill should be easily removed. If the chuck is equipped with a locking mechanism, then the release of the drill should be started by pressingstop key. In order to rotate the adjusting mechanism, it is necessary to fix the fixed component of the cartridge.

In the case when it is not possible to turn the adjusting sleeve, it is necessary to try to increase the force. You can also create an initial push that allows you to break the movable element from its place. To begin with, it is worth trying to turn the sleeve sharply by hand. If this attempt fails, you can try to accelerate the cartridge to maximum speed in reverse mode, and at this moment try to clamp the sleeve with your hand. This is an effective way to get the drill out of the drill.

Further, if the previous attempts were unsuccessful, you can apply force with a wooden or rubber mallet. To begin with, having fixed the fixed part of the cartridge, it is necessary to strike the sleeve, only not at the end, but along a tangential trajectory. You can also strike the wrench handle, creating an instant point force. To achieve the maximum effect when trying to unlock the cartridge, it is advisable to introduce lubricant into its internal cavity, which will create favorable conditions. This is how it will turn out to pull the drill out of the drill with your own hands. But this is not the only way.

Removing the drill from the chuck using a vise

To apply more force to the adjusting sleeve, it is recommended to use a vise. To do this, it is necessary to securely fix the drill in the chuck in them. Moreover, the drill itself should be placed horizontally to the surfaceworkbench. Next, using a light hammer, you need to lightly tap the chuck adjusting sleeve in a circle.

The process itself consists of sharp blows applied to the sleeve along a tangential trajectory. When the sleeve has succumbed, it should be turned with a pipe wrench. If the attempt did not bring results, the work should be repeated, increasing the force of impact. In order to reduce damage to the surface of the cartridge, it is better to use a bronze hammer for this procedure.
