Changing round holes into a square shape more accurately than traditional push broaches, these broaches go in CNC and milling machines. Use them with a rotary broach holder (sold separately), which slightly angles the broach so only one corner is cutting at a time. The square holes these broaches cut are good for holding square shafts in finished parts. They work on through holes as well as blind holes, which don’t go all the way through. If you’re cutting soft material, don’t have a CNC or milling machine, or don’t need accuracy, use these broaches in the traditional push style, without the holder.

Used in CNC and milling machines, these broaches turn round holes into hexagonal ones with more accuracy than traditional push broaches. Pair them with a rotary broach holder (sold separately), which positions the broach at a slight angle so only one corner is cutting at a time. The hex-shaped holes these broaches create are useful for holding hex-head screws and shafts in finished parts, as well as for cutting hex drives into screw heads. They work on through holes as well as blind holes, which don’t go all the way through. If you’re cutting soft material, don’t have a CNC or milling machine, or don’t need accuracy, use these broaches in the traditional push style, without the holder.

A tolerance of 0” to 0.001” means these broaches cut with a standard degree of accuracy, making them good for most general applications. They’re made of M2 high-speed steel, the standard material for cutting tools.
