Abstract
A material removing tool includes an elongated shank having a rear end portion arranged to be driven by the motor of a boring or milling machine and a front end portion provided with a coaxial stub which is received in a socket between two legs of an adapter which carries the cutting implement. At least one of the legs has a radial hole which is in near register with a tapped bore of the stub. The shank portion of a screw, whose head bears against a conical surface surrounding a portion of the hole in the one leg, meshes with the threads in the tapped bore of the stub to urge the rear edge faces of the legs against complementary surfaces provided on two shoulders forming part of the front end portion of the shank. This enhances the resistance to bending stresses and prevents wobbling or vibration of the adapter relative to the shank. The external surfaces of the adapter and shank are formed with longitudinally extending grooves for evacuation of shavings or chips from the locus of removal of material from a workpiece. The diameter of the hole exceeds the diameter of the tapped bore, and the axis of the tapped bore is nearer to the shoulders of the shank than the axis of the hole. T…
