Abstract

A device for the fine machining of bores such as a reamer or a cutter tip 31 has a cutting edge which is divided into a main cutting edge and a secondary cutting edge 54. Embedded in the parent body 32 is an insert 33 which consists of a carbide backing 43 and a crystalline structure 48 of great hardness, such as polycrystalline diamond PCD or cubic boron nitride CBN, sintered on the carbide backing 43. A transition zone 52 is located in between. The insert 33 is arranged in such a way that the secondary cutting edge 54 is formed in successive sections by the very hard crystalline structure 48, the less hard transition zone 52, the even less hard carbide backing 43, and finally the relatively soft carbide of the parent body 32. The drilling device has a substantially prolonged service life and enables bores having a very good surface quality to be produced. <IMAGE>
