Patent ID: 7568866

Claim:
A tool, comprising: a tip including a working end, a connecting end, and a radially extending abutment surface; a tip holder including a mating end for mating with the connecting end and a radially extending supporting surface for abutting against the abutment surface to limit axial movement of the tip relative to the tip holder, and wherein the connecting end is non-circular and includes a groove and wherein the tool includes an assembly including the tip and the tip holder arranged such that, upon relative rotation of the tip and the tip holder in a connecting direction, an axial force is exerted on the groove and causes the abutment surface to move toward the supporting surface, wherein the connecting end is a shank end and wherein the tip holder comprises an internal axially extending opening for receiving the shank end and wherein the shank end has an external groove therein, wherein the internal axially extending opening includes an internally threaded portion, and wherein the tool includes a sleeve arrangement disposed between the shank end and an internal surface of the internal axially extending opening, the sleeve arrangement including an externally threaded member adapted to engage the internally threaded portion, the sleeve arrangement being adapted to engage the external groove and, at least in part, move axially relative to the tip, and move the tip relative to the tip holder such that the abutment surface moves toward the supporting surface when the externally threaded member is rotated relative to the tip holder.
