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.

  1. 1. Rotatable tool comprising 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, wherein the shank and the drawbar include mutually engageable displacement members for imparting an axial displacement of the drawbar relative to the shank, and the cutting head and the drawbar include mutually engageable force transfer members for transferring forces therebetween in the axial direction, the force transfer members including serrations extending transversely relative to the axis.
  2. 9. Cutting head for rotation about a center axis of rotation and including an axially forward cutting end and an axially rearward engagement portion comprising axially spaced serrations extending transversely relative to the axis.
  3. 13. A drawbar defining a longitudinal axis of rotation and including an axial rear portion adapted to be anchored in a shank, an axially forward end of the drawbar including an engagement portion adapted to receive a cutting head and including axially spaced serrations extending transversely relative to the axis.
