TWO-PART TOOL FOR MACHINING, WITH SCREW COUPLING

摘要

The invention relates to a tool for machining a workpiece, comprising a holder (30) with a receiving opening (32) on an end face thereof, said opening comprising an inner thread (34) and a cutting head (10). The cutting head comprises a head element (12) on the end acting on the workpiece, said head element comprising at least one cutting element (14), and a coupling element (16) on the end connected to the holder, said coupling element comprising an outer thread (18) corresponding to the inner thread (34) of the receiving opening (32). The thread pitches of both the outer thread (18) and of the inner thread (34) are interrupted by a threadless surface (20, 36) in at least one specified angle sector along the outer circumference of the coupling element (16) and the inner circumference of the receiving opening (32) respectively.
