The cutting tool industry has become the pioneer in the use of hard coatings on different types of tools. Hard coatings, which improve the performance and lifetime of cutting tools, have been used for more than 20 years. In the study reported here, performance evaluations were made of high-speed steel and carbide tool inserts that were coated with tungsten disulfide (WS{sub 2}), titanium nitride (TiN), and with TiN and then with WS{sub 2}; uncoated inserts were also evaluated. The aim was to determine whether the WS{sub 2} coating improved tool life and reduced cutting-force requirements. The WS{sub 2}-coated inserts demonstrated significantly lower flank wear than the uncoated inserts. Use of WS{sub 2} also reduced flank and notch wear of uncoated and TiN-coated inserts. The greatest wear reductions were observed for inserts coated with both TiN and WS{sub 2}.
