Abstract:
a cutting tool assembly including, a shank for mounting the cutting tool assembly on a cutting machine, a cartridge which is mountable on the shank, a cutting means on the cartridge, and releasable screw means for securing the cartridge on the shank, wherein the shank includes a seating portion for engaging the cartridge and the cartridge includes a complementary seating portion for engaging the shank, wherein each seating portion is defined by planar surfaces which converge such that one seating portion is an extending bearing part and the other is a recess within which the bearing part wedges on tightening the screw means to secure the cartridge on the shank, the screw means being positioned to act in a direction towards which the planar surfaces converge to increase the wedging of the bearing part in the recess, whereby substantially all cutting forces are transmitted from the cartridge to the shank via the wedged seating portions.
