| 摘要 |
The invention relates to a modularly constructed tool retainer (10), comprising a main body (11), which extends along an axis of rotation (2) and which is functionally divided into a shaft section (12) for coupling to a machine tool spindle and a clamping section (20) having a central accommodating bore (21a) for accommodating and clamping a cutting tool (50), which has at least one cutting edge, and a cutting head (30), which is arranged concentrically to the main body (11) and is detachably fastened to the main body (11) and has at least one cutting edge, which is arranged at a predetermined axial and/or radial and/or angular position relative to the at least one cutting edge of the cutting tool (50). According to the invention, the cutting head (30) has a sleeve section (40), which extends the tool retainer (10) and which has a central passage bore (41) arranged concentric to the central accommodating bore (21a) of the clamping section (20) for accommodating and radially supporting a tool shaft part of the cutting tool (50) protruding from the central accommodating bore (21a) of the clamping section (20). |
