Manufactured to the DNMG150408-MS3 WSM01 designation, this insert features a TiAlN and Al2O3\/ZrN multilayer PVD coating that extends tool life in demanding cut conditions. The MS3 chip breaker geometry is optimized for medium finishing and semi-finishing passes. The insert is neutral-hand, carries a negative rake angle of 13 degrees, and delivers four usable cutting edges per insert. An insert length of 15.50 mm and a 0.8 mm corner radius make it well-suited for controlled depth-of-cut applications where surface finish and edge stability are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, boring, and back turning operations. Its primary target workpiece materials are stainless steel, superalloys, and titanium  -  material groups M and S in the ISO classification system. It also performs in secondary applications on steel, non-ferrous metals, and hard materials (ISO P, N, and H). The WSM01 grade and PVD coating process make this insert a practical choice for shops running stainless components, aerospace alloys, or titanium parts where built-up edge and heat management are ongoing concerns. Licensed machinists and CNC operators in job shops, aerospace, and medical manufacturing are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN and Al2O3\/ZrN PVD multilayer coating for heat and wear resistance in M and S workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMS3 chip breaker geometry designed for medium finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert  -  neutral hand, usable in standard DNMG toolholders\u003c\/li\u003e\n  \u003cli\u003e0.8 mm corner radius with honed cutting edge style for consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eSuitable for turning, facing, boring, and back turning in a single insert\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code DNMG150408-MS3 WSM01, industry standard number DNMG432-MS3 WSM01\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard DNMG insert-style toolholders that accept a 55-degree diamond insert with a clamp-and-pin holding method, a 5.16 mm hole diameter, and an inscribed circle of 12.70 mm.

Power down and lock out the machine spindle before seating or rotating the insert. Use the correct torque driver for the clamp screw  -  follow the toolholder manufacturer's torque specification, as this insert does not carry its own clamp torque value. Inspect the insert pocket and locating pin for wear or debris before seating a new edge; a contaminated pocket will shift the insert position and degrade surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150408-MS3 WSM01\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMG432-MS3 WSM01\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, Al2O3, ZrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM01\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MS3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.8 mm (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.50 mm (0.6104 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.50 mm (0.6100 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 5.16 mm (0.2030 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium (ISO M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Non-Ferrous Metal, Hard Material (ISO P, N, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M10, S10, P10, N10, H20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6890874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51958561866034,"sku":"6890874","price":381.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57c3293365d91cc2123797b74b36254e.jpg?v=1789945157","url":"https:\/\/voomisupply.com\/products\/walter-6890874-turning-insert-dnmg150408-ms3-wsm01-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
