The head (1) of the planing tool includes a plurality of helical grooves (2) of dovetail cross-section uniformly distributed over its periphery. Wedging devices (6) with knives (5) resting thereon are insertable sideways in the grooves. Disposed in each wedging device is a securing arrangement (7), actuation of which causes the associated wedging device-and-knife assembly to be pressed against the outwardly tapering sidewalls (17, 18) of the respective groove and held fast. Each of the knives has two opposite cutting edges (19, 20), either of which can be brought into operating position by reversing the knife. A second groove (16) runs parallel to each first groove (2) for receiving a guide component of a knife-aligning device. Owing to the helical configuration of the grooves and the precisely aligned cutting edges of the reusable knives disposed in the grooves, vibration-free machining of workpieces with planing widths of up to more than two meters is possible.
A planing tool for a woodworking machine, of the type having a substantially cylindrical head including at least a first helical groove of substantially dovetail cross-section extending from one end of the head to the other and having a bottom and two sidewalls, and at least one knife disposed in said first groove and having two flat sides, wherein the improvement comprises:
