Tiger·tec® Gold WSM37G from Walter is a wear-resistant thread milling grade with the unique, one-of-a-kind, physical vapor deposition (PVD) aluminum oxide (Al2O3) coating technology. The multiple-layer coating features a titanium aluminum nitride (TiAlN) coating on the carbide substrate for a high level of wear resistance, followed by Al2O3 coating for high temperature resistance and topped with zirconium nitride (ZrN) for excellent friction-reduction characteristics and the best wear detection because of its gold color.
The indexable inserts made of this universal grade are effective for machining blind-hole and through-hole threads in steel, stainless steel, cast iron, heat-resistant super alloys and steel with a hardness up to 55 HRC (ISO P, M, K, S and H material groups). The grade WSM37G inserts are for milling threads with a nominal diameter from UNC 3/4 or 16 mm with a pitch range from 3 to 18 threads per inch (TPI) or 1.5 to 10 mm.
Tiger·tec Gold grade WSM37G inserts are offered in two easy-cutting geometries with a positive basic shape and each with three cutting edges. Both have an extremely smooth, low-friction rake face and defined corner radii for producing threads in accordance with many international standards. The D67 universal geometry is for achieving maximum tool life. The D61 geometry with anti-vibration land is for thread milling with a high level of operational smoothness when using large projection lengths or under difficult machining conditions. Walter developed these chip breakers with grade WSM37G specially for thread milling.
Potential benefits of the Tiger·tec Gold grade WSM37G inserts include process reliability because of the perfect balance between wear resistance and toughness, high productivity due to optimal cutting parameters, and universal application even under difficult thread milling conditions. All Walter T2710 to T2713 thread milling cutters accept the grade WSM37G indexable inserts.
