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 reces s(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 portio n (120) extending in rearward direction therefrom. The cap portion (118) inc ludes 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 plu rality of head fixation surfaces (128). In the assembled tool (90), the tool shank's forwardly facing shank support surfaces (262) support the cutting h ead's rearwardly facing head base surfaces (124), while the plurality of hea d fixation surfac.es (128) abut the plurality of shank fixation surfaces (28 6, 288, 290).</p> |
