Abstract

A reamer has a basic tool body made of hard metal (12) and a plate-like cutting insert (18) inserted into a recess (28) at the front. The cutting insert (18) is at least partially made of polycrystalline diamond, its cutting edges (20) situated axially offset relative to the cutting edges (30) on the basic tool body (12), thus engaging with the workpiece later.
