ABSTRACT:
A rotatable tool includes a shank rotatable about a longitudinal axis, a drawbar mounted to an axial front end of the shank, and a cutting head mounted to an axial front end of the drawbar. The shank and the drawbar include mutually engageable screw threads which impart an axial displacement of the drawbar relative to the shank. The cutting head and the drawbar include mutually engageable serrations for transferring axial force therebetween. The serrations are axially spaced from one another and extend transversely relative to the axis.
