Abstract
A cutting tool assembly comprising a tool holder with a clamping collet and an interchangeable tool insert with a clamping shaft engageable by the clamping collet, matching conical surfaces on the periphery of the tool holder and of the tool insert providing centering as well as axial and radial force transmitting functions, while cooperating spline profiles on the assembly components provide a separate tangential force transmitting function. The clamping collet and the clamping shaft engage each other with multiple conical coupling faces which, under a pulling action of a rod connected to the collet, produce an axial pull on the tool insert while spreading radially between the clamping shaft and the tool holder to produce a radial wedging action. These conical coupling faces may be part of axially spaced identical ridges, the clamping collet expanding radially to clear the ridges for insertion, or they may be flanks of cooperating threads, the clamping collet being rotatable. Segmentation of the threads and an axial abutment reduce the rotational insertion movement.
