Terms used for broaches:

The shank servers to fix the broach in the slide block of the machine.The pilot must fit in the pre-machined slot of the work piece with a tight clearance fit and guide the broach when cutting.The cutting body contains rows of roughing and finishing edges, the depth of cut being lower for the finishing row.The sizing row has no stepped teeth and does not cut. Its four to six teeth go over to the cutting body when the broach is sharpened. The end of the work piece has another pilot so that the broach remains steady in the finished opening at the end of the broaching operation.
