A broach for the surface machining of precast or preforged round pins on workpieces, in particular on crankshafts, which round pins are set in rotation for this purpose, is designed in such a way that the broach cutting edges are parts of interchangeably fastened cutting bodies (4) of a hard cutting material and form an acute angle (5, 6) with the longitudinal axis (7) of the broach at least in the rough-machining area (part A and B) of the broach for the pull cut. <IMAGE>
