It carries the ISO designation DNGG150408-MS3 WSM01 and ANSI code DNGG432-MS3 WSM01. The insert features a TiAlN, Al2O3, and ZrN multi-layer coating applied via PVD process, delivering strong heat and wear resistance at the cutting edge. The 55-degree diamond (rhombic) shape provides four usable cutting edges with a neutral hand orientation, a honed cutting edge style, and a 0.8 mm corner radius. This insert is installed by machinists and CNC turning specialists in roughing and medium machining operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for roughing and medium machining applications on stainless steel and superalloys and titanium as primary workpiece materials. Secondary materials include steel, non-ferrous metals, and hard materials. Supported operations include turning, facing, boring, and back turning. The MS3 chip breaker geometry is engineered for chip control across these demanding material groups, making this insert a practical choice for shops running high-alloy or difficult-to-machine workpieces on CNC lathes and turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN, Al2O3, and ZrN PVD coating for wear resistance in stainless steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with four cutting edges, maximizing cost per edge\u003c\/li\u003e\n\u003cli\u003eMS3 chip breaker designed for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e0.8 mm corner radius (1\/32 inch) with honed edge preparation for edge stability\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of 13 degrees with neutral hand  -  fits standard DNGG toolholders\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible; hole diameter 5.16 mm (0.203 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard DNGG toolholders accepting inserts with ANSI code DNGG432 and ISO code DNGG150408, with clamp or pin insert holding.
