Abstract:
1. An insert seat with an indexable cutting insert having two working surfaces facing away from one another and comprising a through-hole extending between the working surfaces for accommodating a fastening bolt, comprising in each case a circumferential lip rim having a cutting edge on each working surface and a central hollow bordered in a ring-like manner by the lip rim and having a number of segment-like molded bodies, corresponding to the number of the different cutting positions of a working surface, for positioning the indexable cutting insert in the respective cutting position, comprising molded bodies having segment-like surfaces in the form of segment-like recesses or segment-like and relief-like projections, wherein the flat surfaces of the molded bodies lie in one plane, and these surfaces extend at an angle of 90° to the center line of the through-hole, wherein the insert seat comprises a supporting surface on the insert seat which faces the positioning surface of the indexable cutting insert and has at least one molded body receptacle, in particular a stop edge on the insert seat, designed to be at least partly complementary to the molded bodies, wherein the indexable cutting insert further includes a bearing surface arranged between the lip rim and the hollow for enabling the indexable cutting insert to bear against the stop edge on the insert seat to securely hold the indexable cutting insert in the insert seat.
