Abstract (en)

[origin: CA2202260A1] 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.
