Abstract

For metal-cutting tools, the problem of increasing their durability has always been relevant. In this work it is shown the possibility of hardening of spiral drills from high-speed steel with an increase in resistance by 1.8 times by applying the method of magnetic-pulse processing for the optimum technological regime.
