<p>A metal cutting tool (90) has a cutting head(lOO) releasably mounted on a front end of a tool shank(200), in a self-clamping manner. The tool shank's forward end is provided with a pair of shank coupling portions (256A, 256B), each having a forwardly facing shank support surface (262). A pocket recess(264) is defined between the shank's coupling portions (256A, 256B). Within the pocket recess(264) are a plurality of shank fixation surfaces (286, 288, 290). The cutting head (100) has a cap portion (118) and a fixation portion (120) extending in rearward direction therefrom. The cap portion (118) includes a pair of head segments (140A, 140B), each having a rearwardly facing head base surface (124). The cutting head's fixation portion (120) has a plurality of head fixation surfaces (128). In the assembled tool (90), the tool shank's forwardly facing shank support surfaces (262) support the cutting head's rearwardly facing head base surfaces (124), while the plurality of head fixation surfac.es (128) abut the plurality of shank fixation surfaces (286, 288, 290).</p> |
