Abstract
A quick-change insert, particularly for hard alloy taps, has a seat for a square end section of the tap forming the rotational connection and a pull-out holding device. In the region of the square end section, at least one indentation is provided for the positive engagement of a locking pin, which is under the tension of a spring, mounted in the quick-change insert with limited longitudinal mobility and, in use, is blocked by an overlapping collar of the chuck body.
