Walter CNMG160616-RP5 WPP30S Tiger-tec Silver Carbide Turning Insert

These are new Walter CNMG160616-RP5 WPP30S carbide turning inserts in the Tiger-tec Silver CVD coating platform, made in Germany and sold as a full 10-piece tray. The ISO designation decodes as follows: C = 80° rhombic (diamond) shape, N = 0° clearance angle, M = tolerance class (±0.08mm thickness/±0.05mm inscribed circle), G = with hole and top/bottom chip grooves, 16 = 16mm inscribed circle, 06 = 6.35mm thickness, 16 = 1.6mm nose radius, RP5 = Walter's positive roughing chipbreaker geometry for heavy interrupted and continuous cuts. Grade WPP30S is a CVD-coated cemented carbide in Walter's Tiger-tec Silver series, engineered specifically for steel (ISO P) turning across medium to heavy roughing applications; the label confirms primary P-material suitability with double-dot rating. Tiger-tec Silver CVD coating delivers enhanced wear resistance and toughness compared to earlier Tiger-tec Gold, making WPP30S well-suited for high-feed roughing of carbon steels, alloy steels, and cast steels at elevated cutting speeds. Compatible toolholders use CNMG 544 seating (per the CNMG544-RP5 ANSI equivalent shown on the label) in standard negative-rake PCLNR/PCLNL and equivalent external turning toolholders with 16mm IC insert pocket.
