This insert features an 80-degree diamond shape with a neutral hand orientation and a 0.1 mm corner radius, making it well-suited for controlled chip formation in demanding materials. The TiAlN, Al2O3, and ZrN multi-layer coating is applied via PVD process, delivering thermal resistance and wear protection at the cutting edge. With four usable cutting edges and a honed edge style, the insert provides consistent performance across turning, facing, and boring operations. Licensed machinists and CNC operators working with tight tolerances will find the CNGG-MS3 series geometry and WSM01 grade combination effective for high-productivity finishing and semi-finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed primarily for machining stainless steel and superalloys including titanium, corresponding to ISO material groups M and S. It also supports secondary applications in steel, non-ferrous metals, and hard materials (ISO groups P, N, and H). The MS3 chip breaker geometry is optimized for controlled chip evacuation in these material families. Typical install scenarios include CNC turning centers and manual lathes where clamp-and-pin insert holding is used. The insert conforms to both ANSI and ISO standards and is identified by ISO code CNGG120401-MS3 WSM01 and industry standard number CNGG4(3)0.2-MS3 WSM01.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN, Al2O3, and ZrN PVD multi-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake angle of 13 degrees\u003c\/li\u003e\n  \u003cli\u003eMS3 chip breaker geometry suited for stainless steel, superalloys, and titanium (ISO M and S groups)\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert with honed edge preparation for consistent edge integrity\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation supports turning, facing, and boring in a single insert style\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatible with standard CNGG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGG-style toolholders that accept clamp-and-pin insert retention.

Always de-energize and lock out the machine before indexing or replacing inserts. Inspect the toolholder pocket and clamping pin for wear or debris before seating a new insert, as a compromised pocket will affect edge life and surface finish. Follow the toolholder manufacturer's clamping torque guidance and verify insert seating before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNGG120401-MS3 WSM01\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80-degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM01\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\u003eChip Breaker\u003c\/strong\u003e: MS3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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: 0.1 mm (0.004 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (0.500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.508 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\u003eWidth\u003c\/strong\u003e: 12.90 mm (0.508 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 5.16 mm (0.203 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 12.90 mm (0.508 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\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: 0.22 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: 7021455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51995553595698,"sku":"7021455","price":444.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bea10e571b4612a907d6755ffd43192_7c96ea0a-b62d-4ee1-8f66-08c3f3dfe71b.jpg?v=1789992764","url":"https:\/\/voomisupply.com\/products\/walter-7021455-turning-insert-cngg120401-ms3-wsm01-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
