ABSTRACT:
A device for cutting truncated dowels from a board, with a device including a one-piece cutting body shaped as a hollow cylinder and having a concentric clamping shank. The cutting body is provided with only one recess which forms a knife edge, with the recess opening toward a front of a cutting body and merging into a wider dowel ejection opening. The cutting body has an inside annular cutting edge which determines the larger outside diameter of the truncated dowel to be cut and from which the knife edge originates. The inside circumferential surface of the jacket tapers conically toward the clamping shank, and the knife edge is inclined obliquely inwardly in accordance with the conicity of the inside circumferential surface.
