A cutting tool assembly which includes a shank (1) and a removable cartridge (3) on which is mounted a cutting insert (5). The shank (1) is for mounting the assembly on a cutting machine. The cartridge (3) is removably mounted by a screw fastener (7) which passes through a hole in shank (1) into a threaded hole (31) in cartridge (3). The shank includes a recess (9) having sloping facing walls (15, 17) for engaging a complementary seating portion, having sloping walls (25, 27), of cartridge (3). The recess (9) and complementary seating portion of the cartridge are shaped such that the cartridge is wedged in the recess when the screw fastener (7) is tightened. The invention allows a reduction in costs by providing for the exchange of cartridges rather than a whole cutting tool. The wedging interconnection of the cartridge and shank ensures rigidity of the assembly. A modification is described wherein a recess for a screw fastener is provided instead of a hole (23) which allows for quick exchange of cartridges. |
