A B S T R A C T The invention concerns a three-edged tool (12) for a woodworking machine. The edges (18,19,20) of the tool are arranged with equal angular spacing about a tool body and protruding therefrom. In the surfaces (24,25,26) between the edges are recesses (27,28,29) which are shaped on one hand to retain the tool by mating engagement with a correspondingly shaped protrusion (30) provided on a tool carrier (10), on the other hand to act as a kerf in order to guide a break in case of overload of an edge (18) to the area between two recesses (27,28). Fastening means for the tool include a support part (14) provided on the tool carrier and a clamping part (15). The support part (14) carries the protrusion (30), which is shaped to engage in a recess (28) of the tool, and has a support surface (14') for supporting a clearance surface of an edge (19) which is inactive when the tool is mounted on the tool carrier. The clamping part (15) has a clamping surface (22) which is adapted to press against the clearance surface of the second inactive edge (20) of the tool. Fig. 2
