摘要

To achieve reliable fastening of a toothed cutter carrier on the toothed bearing surface of a tool body, and to achieve favorable force ratios, in a rotary cutting tool, in particular a drilling head, the tooth formation of the bearing surface is constructed in a sawtooth shape with steep tooth flanks and inclined tooth flanks, the steep tooth flanks being disposed substantially on that side of the teeth which is orientated towards the cutting element of the cutter carrier. The tooth formation on the cutter carrier is constructed so that it is substantially similar to the tooth formation of the bearing surface for interengagement therewith.
