Walter USA Expands Thread Milling Grade Options
Walter has expanded its product range with the addition of the new thread milling grade, Tiger∙tec Gold WSM37G. The grade features the only PVD aluminum oxide (Al2O3) coating technology of its kind in the world, which provides an elevated level of temperature resistance and long tool life.
A titanium aluminum nitride (TiAlN) base coating on the carbide substrate offers a high level of wear resistance and the multi-layer coating is topped with a polished gold-colored zirconium nitride (ZrN) layer with the best friction resistance and wear detection. In addition, an extremely smooth rake face minimizes friction.
These new benchmark indexable inserts for thread milling have a positive basic shape geometry that has three cutting edges. They are available in either the D67 universal geometry for maximum tool life or the D61 geometry with anti-vibration land for a high level of operational smoothness when using large projection lengths or under difficult conditions.
WSM37G-grade inserts are for milling threads with a nominal diameter from 16 mm or UNC ¾. The indexable inserts can be used universally to thread mill steel, stainless steel, cast iron, non-ferrous metals, heat-resistant super alloys and steel hardened up to 55 HRC (ISO P, M, K, N, S and H).
Thread milling inserts in grade WSM37G feature chip breakers specifically developed for thread milling and a defined corner radii for producing threads in accordance with various standards. End users will realize process reliability due to the perfect balance between wear resistance and toughness.
