A bit can jam for a number of reasons, one of which is the use of the largest sized drill bit. The jaws of the chuck have to be pushed to the limit. and then there is no way to squeeze them. If they are not squeezed evenly, they cannot be unclamped to pull out the jammed drill bit or bit.

If the jaws jam, the bit may jam due to a free play during clamping and unclamping. This happens if you get under the shaped parts of the cams:

When these situations occur, it is impossible to work with the tool, even if it is in good working order. You can try to fix it yourself, or if you can’t, you can call in a specialist. Almost all screwdriver models are the same, so the ways to remove a jammed bit are the same.

The first thing to do is to add lubricant to the jammed chuck to make it open. WD-40 is a great grease for this purpose. It is poured so much that the liquid flows over each cam. Leave the grease in for 15 minutes. then gently tap the cams through the cloth. Most often after such a procedure, the problem can be solved.

Some remove the bit with adjustable wrenches. after the chuck is lubricated, one clamps the base, the other gently twists its top. Once you can get the jammed bit, you need to clean the electric screwdriver.

The bit is magnetized for convenience

Magnetizing and hardening the bit

The bits on sale are mostly made in China. They are made of soft material, which causes rapid loss of their original shape. It cannot be regenerated, so these types of bit are characterized by a short service life.

To avoid having to buy new bits all the time, it is recommended to harden them. To perform the procedure, a piece is wound onto the nozzle, and it is heated to red over a gas burner. After the tooling has become reddish, it is lowered into a tin can, previously filled with machine oil for 5-6 seconds. This operation should be repeated several times, with pauses for 2-3 seconds. The element is considered to be hardened after blackening.

The magnetizing procedure will make the work more comfortable. There are several methods:

  • The bit is placed with its working ends between 2 neodymium magnets, which are placed so that they repel each other. To hold them in place, they are joined with plasticine. You will have to wait at least 10 hours for the effect.
  • Insert the bit in a special device to magnetize and demagnetize screwdrivers. The desired effect is achieved by placing the element in a square window.
  • Wrap the copper wire, which has been previously stripped of insulation, in 3 layers on a plastic tube. They put a nozzle inside. Connect the ends of the wire to the battery terminals or the battery. To enhance the effect, connect 2-3 batteries in series. After a minute they evaluate the result of magnetization.
