FIELD: technological processes.
SUBSTANCE: deforming-cutting broach has cutting teeth with annular cutting edge and deforming elements with inclined teeth arranged on them, which are installed with the possibility of rotation relative to axis of broach and neighboring elements. In order to increase resistance of cutting teeth by rising of cutting edge displacement speed versus cutting surface, deforming and cutting elements are arranged as a whole, and deforming teeth are arranged behind back surface of cutting teeth at the same by opposite angle to axis of broach at each following element, and value of angle is selected within the limits from 17 to 25°.
EFFECT: improved resistance of cutting teeth.
