Abstract: The description shows a chip breaker system for a drilling, turning, milling or reaming tool, wherein the chip breaker system comprises: a portion of a flute and a first area which is produced by a progressive cut, wherein a first edge is arranged between the portion and the first area in such a way that chips produced by a cutting movement of the drilling, turning, milling or reaming tool can be broken at the first edge. The application further relates to a high-speed reamer comprising such a chip breaker system, a reamer made of solid carbide, a reamer with axially extending cooling channels which are disposed in a decentralized manner, a reamer with cooling channels which are unevenly distributed in the peripheral direction, and a reamer with cooling channels, wherein the outlet openings of the cooling channels are arranged on different cutting planes.
