Where applications demand precise thread quality and improved threadmaking productivity, WIDIA-GTD HSS-E taps are the answer, according to the company.

These powder-metal taps represent the optimum combination of grade, geometries and coatings for accomplishing precision tapping applications in steel and stainless steel materials. The powder-metal substrate contains higher than standard levels of cobalt content for a combination of more 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 toolholders.

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.
