摘要

2119258 9307982 PCTABS00021 A cutting toolholder assembly for holding a cutting tool (26) used in a material removal operation. The assembly comprises a locking component which contains a bore (32) with at least one recess (34) therein. The assembly also includes a tool holding component (24) with a shank (48) whereby the bore receives the shank. The shank contains a compartment (50) with a locking assembly within the compartment. The locking assembly includes at least one locking member (56) and a positioner assembly (58) that selectively positions the locking member into engagement with its corresponding recess. The recess corresponds to the shape of the locking member such that when the locking member engages the recess, the recess restrains the locking member so that there is essentially no movement between the holder component and the locking component during a material removal operation.
