Built from carbide substrate and finished with a multilayer PVD coating of TiAlN, Al2O3, and ZrCN under the proprietary WSM30 grade designation, this insert delivers heat resistance and edge toughness in demanding cuts. It features a 1\/2-inch inscribed circle, a 3\/16-inch thickness, a 1\/32-inch corner radius, and an 80-degree trigon shape with a neutral hand orientation. Six cutting edges per insert extend tool life between index cycles. The NM4 chip breaker geometry is optimized for roughing and medium machining operations. Licensed machinists and CNC operators working in production or job-shop environments install this insert as part of a toolholder and clamp or pin retention system.\u003c\/p\u003e\u003cp\u003eThis insert is primarily rated for stainless steel, superalloys, and titanium (ISO material codes M and S). It is also suitable as a secondary application in steel cutting (ISO code P). Typical use cases include turning, facing, and boring operations where consistent chip control and edge security are required across variable stock conditions. The negative rake and negative side clearance geometry suit interrupted and continuous cuts at medium-to-heavy material removal rates, with a maximum depth of cut of 0.2278 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer PVD coating: TiAlN, Al2O3, and ZrCN for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eWSM30 carbide grade rated for stainless steel, superalloys, titanium, and steel\u003c\/li\u003e\n\u003cli\u003eNM4 chip breaker geometry supports roughing and medium machining\u003c\/li\u003e\n\u003cli\u003eSix usable cutting edges per insert reduce cost per edge\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert compatible with clamp and pin toolholder retention\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for improved edge stability on tough workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit WNMG-series toolholders using clamp or pin retention that accept a WNMG432 (ANSI) or WNMG080402 (ISO) insert size with a 0.2030-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert  -  do not overtighten by hand estimation. Inspect the insert pocket and seating surfaces for debris or damage before each index to maintain accurate cutting geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: WNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: WNMG080402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: W - Trigon 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6840 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2278 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, Al2O3, ZrCN (Multilayer PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NM4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\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\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Retention 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\u003eInsert Material\u003c\/strong\u003e: Carbide\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: 0.02425 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5357524\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51994532839730,"sku":"5357524","price":324.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7ee81f73f5c68882df265094ad2e207_cce53092-64f7-4653-862d-70b4ae8951a4.jpg?v=1789991981","url":"https:\/\/voomisupply.com\/products\/walter-5357524-turning-insert-wnmg432-nm4wsm30-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
