摘要： An internal broach for the broaching of profiles defined by a bottom and flanks, in particular of internal toothings, in a workpiece is provided with broach cutting teeth which have bottom-cutting edges and flank-cutting edges. Over their full profile height, the flank-cutting edges of broach cutting teeth disposed one after the other and allocated to each other have an ascending profile in the range of 1 .mu.m to 3 .mu.m.
