A cutting tool assembly having a longitudinal axis comprises a cutting insert (3) to be releasably retained in a tool holder (1). The cutting insert (3) is formed with a through bore (21) having spaced apart, peripherally located, radially directed support wings (22). The tool holder (1) is provided with a coupling member (11) having a plurality of corresponding radially extending abutment wings (15). The coupling member (11) of the tool holder (1) is rotatable and axially displaceable with respect thereto. The releasable retaining of cutting insert (3) in the tool holder (1) is effected by the insertion of the coupling member (11) of the tool holder (1) into the through bore (21) of the cutting insert (3) with the abutment wings (15) passing between and beyond successive support wings (22), rotating the coupling member (11) so that the abutment wings (15) are aligned with and overlay the support wings (22) whilst axially displacing the coupling member (11) until the abutment wings (15) clampingly abut the support wings (22). |
