The broach cutting teeth (21a-21f) of a toothed section are counter to a direction of broaching to which a shank leads. The broach cutting teeth have bottom cutting blades (23a-23f), guide flanks (25a-25f) on a first side, flank cutting blade relief surfaces on a second side, guide edges without cutting ability on a first edge and flank cutting blades (27a-27f) on a second edge. |
