Part of the T-Max P series, this insert features a CVD-applied multilayer coating of Al2O3, TiCN, and TiN, which provides thermal resistance and wear protection during continuous and interrupted cuts. The trigon (W) insert shape provides 6 cutting edges per insert, reducing tooling cost per edge. With a 3\/8-inch inscribed circle and a 1\/32-inch corner radius, it is sized for standard medium-duty turning toolholders. Installation requires no special tooling beyond a standard torx or hex key for clamp or screw holding.\u003c\/p\u003e\u003cp\u003eThis insert is primarily suited for turning steel (ISO material group P) and cast iron (ISO material group K) in production machining environments. The QM chip breaker geometry is engineered for general-purpose medium turning, offering reliable chip control across a range of feeds and depths of cut. The neutral hand orientation makes it compatible with both right-hand and left-hand toolholder configurations. It is commonly used in job shops, production facilities, and manufacturing operations where consistent surface finish and tool life on ferrous materials are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiCN, and TiN for wear resistance and heat dissipation\u003c\/li\u003e\n\u003cli\u003e6 usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eQM chip breaker geometry for reliable chip control in medium turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with right-hand and left-hand toolholders\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method for secure seating in T-Max P compatible holders\u003c\/li\u003e\n\u003cli\u003eISO code WNMG 06 04 08-QM 4425 for cross-referencing with standard toolholder catalogs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with toolholders in the SANDVIK COROMANT T-Max P series that accept WNMG 06 04 08 (WNMG332) insert geometry.
