摘要：
The invention relates to a cutting tool (10, 40, 54), especially a friction tool, milling tool or drilling tool, with at least one cutting insert (14, 42, 56) fastened on a tool body (12) and comprising at least one free surface or at least one round, beveled surface and preferably comprising at least one free surface, preferably consisting of polycrystalline diamond (PCD) or cubic boron nitride (CBN). In order to improve the cooling, the removal of chips and the lubrication of the at least one cutting insert, it is provided that a coolant conduit (30) run through the tool body (12) forms a connection to at least one coolant conduit section (32, 34, 72) worked into the cutting insert (14, 42, 56) and with at least one mouth opening (36, 70, 76) in the round, beveled surface (60) and/or free surface (24, 44, 62) of the cutting insert (14, 42, 56).
