A high speed planer head. A threaded member (34) having a frustoconical portion wedges against a knife (104), to clamp a knife to a hub for rotating the knife about an axis of revolution. The knife has a front and back side, two cutting edges (136a, 136b) and mirror image symmetry about a mirror plane passing through the knife. To cut both a planar face and two opposed, radiused corners, the cutting edges include respective linear face-cutting portions disposed between two concave, arcuate corner-cutting portions.
L'invention concerne une tête de raboteuse à grande vitesse. Un élément fileté comportant une partie tronconique est calé contre un couteau, de manière à serrer le couteau contre un moyeu en vue de la rotation du couteau autour d'un axe de révolution. Le couteau comporte une face avant et une face arrière et deux arêtes de coupe, et présente une symétrie d'image miroir autour d'un plan miroir traversant le couteau. Afin de couper une face plane et deux coins arrondis opposés, les arêtes de coupe comprennent des parties de coupe de face linéaires respectives, placées entre deux parties de coupe de coin arquées concaves.
