The Walter T2711 and T2712 thread milling cutters, are tools for producing small blind-hole and through-hole threads in dimensions of M16, M18 and UNC ¾. A patent-pending, highly textured MT-TiCN layer for the WSM37S and a TiAlN-Al2O3 coating for The WSM37G helps reduce flank face wear and increases toughness. WSM37G, this Al2O3 layer additionally improves chip breaking, while the gold-colored top layer helps improve wear detection. Inserts are available in two geometries; D67 geometry used universally, and D61, which has an anti-vibration land. The inserts have a defined corner radius for generating standard threads. The thread mills offer universal application in steel, stainless steel, cast iron, non-ferrous metals, heat-resistant superalloys up to 55 HRC. Machined flutes prevent the cutter from being deflected by the chips it produces, and internal coolant ensures reliable chip removal.
