An internal broach for internally broaching profiles, defined by a bott om and flanks, of female serrations of a work piece, comprises a toothed por- tion with several rows of broach cutting teeth disposed successively counter to a direction of broaching, successive broach cutting teeth being allocated to each other for broaching a profile. The broach cutting teeth have bottom cutting blades and first and second sides. The first sides are guide flanks, the edges of which are guide edges without cutting ability.
