Where applications demand precise thread quality and improved threadmaking productivity, Widia offers its new high-performance WIDIA-GTD HSS-E taps. These new taps represent an effective combination of grade, geometries and coatings for accomplishing precision tapping applications in steel and stainless steel materials. The proprietary powder-metal substrate contains higher than standard levels of cobalt content for a combination of heat resistance and improved tool life. Choices include 15-degree left-hand helix for pushing chips ahead in tapping through holes or 45-degree right-hand helix for retracting chips from blind-holes. Manufactured to both ANSI and DIN standards, the precision h6 shanks allow these new taps to excel in conventional tap holders with square drive or precision round tool holders. Grades are available for general engineering and vehicle manufacturing applications, such as crank and cam shafts, connecting rods and wheel hubs. Choices also exist for precision aerospace applications, such as valves, fittings and fasteners in stainless steels.
