ABSTRACT:
A cutting tool for rotary cutting includes a rotatable basic body and a replaceable cutting part or loose top, which is connectable to the basic body via a male/female coupling, which includes a groove and a male part. The groove is formed in a front end of the basic body and is delimited by a bottom surface and two side surfaces. The male part is insertable into the groove along the axis of rotation and protrudes rearwardly from the loose top. The male part has an end surface and two flank surfaces. In the front part of the basic body a forwardly open slot is formed, which separates two elastically deflectable legs wich clamp the male part in the groove. In either the end surface or the bottom surface a recess is formed for receiving a projection on the other surface. The recess is larger than the projection in order to enable the male part to reciprocate a short distance in the groove, whereby the loose top is self-centering with respect to the axis of rotation.
