Abstract
The paper presents the results of tool life calculations and testing of threading profiled tools with brazed hardmetal inserts upon surface plasma modification. The tool life of such inserts has been found to be 2.15–2.5 times (by the criteria of optimal and equal wear) that of unmodified ones. Upon re-sharpening of tools, their life becomes shorter due to a decrease in hardness of cutting edges, but is still much longer than that of tools with unmodified inserts.
