How to Get a Drill Out of a Punch

Nowadays, when building robots, you can no longer do without a punch. Using it, you can drill any hole, as well as dismantle the wall or ceiling. Often there is a situation when the drill is stuck in the chuck and it is very difficult or impossible to pull it out. How to pull out the drill yourself? To understand this you need to know the reasons for the emergence of such an urgent problem.

How to Get a Drill Out of a Punch

Varieties and causes of jamming drill in a perforator

There are two varieties of this problem:

  • Either the drill stuck in the drill chuck or adapter chuck for operating a simple drill in a hammer drill;
  • stuck a drill in a perforating cartridge.

The first version of events happens at a time when you need to use a hammer drill as an ordinary drill. In these cases, a transitional chuck is used, the same as in an ordinary drill, it is mounted in the perforator clamp, and then the drilling process is carried out. After completing the required work, it is sometimes simply impossible to calmly pull out the drill, because the chuck is so long that it cannot be unscrewed. This mainly happens when the clamp was not lubricated or clogged.

In order for it to unclench, it is enough to treat it with WD-40, or use kerosene. After some time, you need to tap the cartridge a little while trying to shake the drill with the other hand. After that, the clamp should loosen easily. After this, the empty cartridge must be cleaned and greased.

It’s a completely different matter if the drill is stuck in a perforating cartridge. This does not happen at all, as in the first embodiment. A drill or drill in a drill only feels twisting and occasionally small shock loads, which extend to them only through clamping jaws and continuous emphasis in the bottom of the cartridge. In a punch, a completely different mechanism for transmitting stresses and absolutely no such kinematics of the drill in the chuck. All because it involves the reverse-shock or shock direction of transmission of stresses. Devices take energy from a special hammer, which runs on an electric motor and hits their shank. On the surface of the devices are the so-called grooves, with which they are fixed in the cartridge and can withstand a reasonable load. For cheap tools, steel is used that did not pass hardening, because of this, a shank can rivet in the puncher during prolonged operation.

Ways That Can Help Pull out the Drill (Video)

The punch holder is arranged so that during operation, drilling or drilling equipment moves along the barrel. During riveting, the barrel will not allow the drill to exit easily. You can try to get a drill in the following ways:

  1. It is necessary to clamp the drill in a vice and then slowly loosen the hammer to pull it onto you.
  2. In large tees, the punch itself is clamped, but so as not to cause damage to the body. Then the drill is clamped with a pipe wrench or in a small vise, and then you need to beat them with a hammer while knocking out a drill.

In any of these cases, a few drops of WD-40 will not be superfluous. Very rarely, the drill bit wedges due to the lack of lubrication or clogged cartridge. The fixation ball, in cases where a foreign body is under it, will not allow the drill to exit. To avoid this, it is necessary that the shank on the device is always lubricated.

If the drill got stuck due to the fact that it turned in the chuck, then you need to remove the chuck itself, while dismantling the cap and rubber ring, or try to turn it back 90 °. Because of this, most likely, you will have to replace all the clamping parts on the punch.

But do not forget that if the shank is already broken, it will not work to free the drill. In this case, you need to completely disassemble the punch and already, then knock out the stuck fixture. But again, after such maneuvers, the barrel will need to be replaced.

Recommendations for preventing such cases

When using high-quality drills, the drill in the hammer will never get stuck. But at the same time, you need to beware of fakes, since at the moment there are a lot of them. And in order to prevent such excesses, it is advised to conduct trial work with the purchased device.

There are cases when holes in materials for which the inserted drill is not suitable are made a powerful punch. And then even a high-quality drill will not withstand such loads and rivet.
