摘要

The screwdriver has a screwdriver shank (1) and a screwdriver head (2) that is conically tapered to a point, where the screwdriver head has a twisting. A rotation of the twisting takes place from the shank with respect to a clockwise direction. The screwdriver head is inserted into a shaft of the screwdriver. The rotation of the twisting from the shank takes place against the clockwise direction. The rotation of the twisting amounts to 20-40 degrees, preferably 28-32 degrees. An independent claim is also included for an insertion bit.
