ROTARY-DRIVEN TOOL FOR CUTTING MACHINING WITH A CUTTING BODY

摘要

A rotary-driven tool for cutting machining, in particular a drilling tool with a cutting body (2) and a holder (3) with a shaft piece is disclosed, with at least cutter (6) and a swallow-tail shaped region (10) on the cutting body (2) and a matching swallow-tail recess (13) on the holder (3), wherein the cutting body (2) and the matching swallow-tail recess (13) match each other such that the cutting body (2) can only be inserted in the holder (3) laterally to a longitudinal axis of the holder (3). In order to fix the cutting body (2), opposing flank sections (18, 19) of the swallow-tail recess (10), between which the swallow-tail shaped region (10) fits can be moved over each other by means of a screw connection (4) in the holder (3) and on fixing the cutting body (2) said body is subjected to a force on the axial direction by the screw connection (4). The invention is characterised in that the cutting body is a cutting head (2) and the axial force is exclusively generated by the swallow tail shaped region (10) in cooperation with the swallow tail recess (13) in the holder (3).
