    Abstract: A clamping apparatus (35) for detachably connecting a tool unit (10) to a tool supporter (37) with increased holding force is provided. The clamping apparatus (35) includes a housing (41), a pair of opposing locking spheres (57a, b) within the housing (41), a cylindrical canister member (39) mounted within the housing (41) that is matable with an insert-supporting tool unit (10) and which has a pair of opposing apertures (55a, b) in its sidewalls for conducting the locking spheres (57a, b) from a locking to an unlocking position, and a lock rod (60) reciprocally movable within the interior of the canister member (39) along an axis (A) and having opposing cam portions (64a, b) for radially moving the locking spheres (57a, b) through the canister apertures (55a, b) into wedging engagement with opposing angled walls (30) of sphere receiving openings (20) in the tool unit (10). To increase the mechanical advantage of the wedging action between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10), the aperture walls (56) of the canister member (39) are angled with respect to a line (R) extending radially from the lock rod axis (A) to reduce the angle between the aperture wall (56) and the tool unit wall (30). Such angling increases the force of wedging and locking engagement between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10). In the preferred embodiment, the aperture walls (56) are angled 15 DEG with respect to the aforementioned radial line (R), thereby increasing the holding force of the clamping mechanism (35) by 30 %.

    Abstract: A cutting insert (1) having a chipbreaking configuration for effectively embrittling and breaking thin, foil-like chips (61) produced by drilling or other fine-cutting operations is provided. The cutting insert (1) includes a polygonal insert body (3) having a top surface (5), a side relief surface (9), and a cutting edge (11) defined therebetween, and a chipbreaker (23) formed by an elongated groove (25) disposed on the top surface (5) behind the cutting edge (11) in combination with a plurality of recesses (27) disposed over the groove (25) having opposing side edges (43). The back wall (34) of the groove (25) applies curling forces to the chips (61), while the opposing side edges (43) of the recesses (27) engage and corrugate the chips (61) thereby embrittling them by work-hardening. The corrugated chips are broken by the curling forces applied by the back (34) and rear (42) walls of the groove (25) and the recesses (27) into small pieces that are easily expelled from the vicinity of the cutting operation.
