Abstract

A method of protection of stepped drill against failures during drilling of stepped holes consists in interruption of the motion of shaving during the period to the contact of the cutting edge of each subsequent step of drill with workable material. The invention relates to metal machining and can be used during drilling of stepped holes by twist, stepped drills.
