The variable speed control allows adjustment of the broach cutting speed, so more difficult materials can be broached and to give extended broach life between sharpening.
Notches can be cut in carbon steels, more difficult to machine alloy steels, stainless steels, non-ferrous and plastic materials. The variable speed drive and hard cut broaches allow a wider range of materials to be cut, including stainless steel or more difficult to machine alloy steels.
