Wera 867/4 IMP DC TORX® DIY Impaktor Bits, TORX 20 x 50 mm DIY-B

On this page you will find the most important details of the bit. Below you can read why an impact bit differs from a regular bit and what to look for when choosing one.

Why an impact bit and not a regular bit

An impact driver provides short, powerful impacts in addition to turning force. Regular bits are often not designed for this and can wear out or break more quickly. An impact bit is specially made for this load, which is also why this type of bit can be recognized by the designation IMP in the product name.

Size T20 and length 50 mm: when do you choose this?

The Torx 20 size must fit exactly the profile in the screw head. A bit that is too small causes play and can damage the screw head. The length of 50 mm makes it possible to reach screws that lie deeper or where a short bit cannot reach. Before you order, check which Torx size your screws have and whether 50 mm fits the space in which you work.

Use with your machine

The bit has a standard bit connection and therefore fits in a bit holder or in a machine that accepts bits with this connection. Preferably use the bit in a machine suitable for impact work, so that you also benefit from the design of the bit.
