ABSTRACT:
A tap holder e.g. for threading taps, has a drive body (1) intended for connecting to the chuck of a drive motor. The driving power is transferred by a torque-limiting device (2, 9, 11) to a clamping body (8) intended to clamp the shank (12) of the threading tap. By the clamping body having outer (6) and inner (5) jaws with an intermediate elastic member (7), tool shanks of different dimensions may be accommodated by the clamping body.
