An interchangeable tool part for a reamer includes a hard metal cutting plate. The cutting surface of the cutting plate is arranged at a distance of at least 0.02 mm from the cutting edge on one side in the region of the cut part and at least partially has a peak-to-valley height which increases by at least 0.01 mm in order to assure the production of cut fragments in the main cutting area and to prevent a build up of cuts in the region of auxiliary cutting section and/or to simplify the removal of cuts. Also high targets can be reached by virtue of the fact that the cutting plates define at least one cutting cavity in the cutting surface thereof at a distance of at least 0.02 mm from the main cutting edge on the end side in the region of the entry angle.

Interchangeable tool part for a reamer

A method for coating a tool or tool part, includes providing a base structure of the tool or the tool part at a temperature of 850&#xb0; C. to 950&#xb0; C. and applying at least one layer to the base structure. One or more layers of the at least one layer is formed of a metal carbonitride of composed of at least one of titanium, zirconium, hafnium, vanadium, niobium, tantalum and chromium. The one or more layers of the at least one layer is deposited by a deposition of a gas containing methane, nitrogen and at least one metal compound. After beginning the applying, the temperature is increased by at least 40&#xb0; C. to an increased temperature and the deposition is continued for a time at the increased temperature.
