A broaching tool (12), in particular for cutting or broaching slits, has several mutually spaced disks (10) that rotate around a common axis (33) and are provided with segment-like cutting projections (18, 20, 22, 24) around its circumference. In order to cut or broach slits with as little effort as possible and in a single operation, the distance (26, 28, 30, 32) between successive segment-like projections (18, 20, 22, 24) on each of the disks (10) is at least approximately equal to or larger than the size of the segment-like projections in the circumferential direction, and projections on adjacent disks (10) are mutually offset in the circumferential direction at least in sections of the circumference of the disks.
Un outil à dégorger (12), utile notamment pour découper des gorges, comprend plusieurs disques (10) mutuellement espacés rotatifs autour d'un axe commun (33) et pourvus de segments de coupe en saillie (18, 20, 22, 24) sur leur circonférence. Afin de pouvoir découper des gorges en une seule opération en appliquant une force aussi réduite que possible, les segments successifs en saillie (18, 20, 22, 24) de chaque disque (10) sont mutuellement écartés d'une distance (26, 28, 30, 32) au moins égale ou supérieure à l'extension des segments en saillie dans le sens de la circonférence des disques, et les segments en saillie de disques adjacents (10) sont mutuellement décalés dans le sens de la circonférence au moins dans certaines sections des disques.
