The Walter BCMT160508R-G55 WSP45S is a new, indexable carbide milling insert in Walter's Tiger·tec Silver CVD coating platform, designed for high-performance shoulder and face milling. Decoding the ISO-style designation: B = parallelogram shape (82° included angle), C = 7° clearance angle, M = medium tolerance class, T = with hole and one-sided chipbreaker land, 160508 = 16.0 mm inscribed circle / 5.0 mm thickness / 0.8 mm nose radius, R = right-hand cutting, G55 = Walter's proprietary chipbreaker geometry optimized for steel and stainless steel milling. The WSP45S substrate is a Tiger·tec Silver CVD-coated cerium-oxide-enhanced Al₂O₃ + TiCN multilayer grade rated for ISO P (steel) and ISO M (stainless steel) applications at medium-to-heavy chip loads, as confirmed by the two-dot ratings for P, M, and S on the package label. This insert is Made in Germany and is compatible with Walter's F4042, F4033, and other BCMT-seat shoulder milling cutters requiring 16 mm BCMT-style inserts.
