It features an 80-degree trigon insert shape (WNMG style) with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for wear resistance and thermal protection. The KR chip breaker geometry and neutral hand orientation make it well-suited for cast iron machining operations. With 6 available cutting edges, this insert delivers cost-effective tooling utilization in production turning environments. Licensed machinists and CNC operators working in job shop or production settings are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning cast iron workpieces, corresponding to ISO workpiece material code K. It fits the SANDVIK COROMANT T-Max P series toolholders and is held in place via clamp and pin methods. The neutral hand designation means it indexes into both right-hand and left-hand compatible toolholders, providing flexibility across turning setups. It is applicable in external and facing operations where consistent chip control and dimensional accuracy are required on cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated with TiCN, Al2O3, and TiN multilayer for extended tool life in cast iron applications\u003c\/li\u003e\n  \u003cli\u003e80-degree trigon (WNMG) shape provides 6 indexable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eKR chip breaker geometry optimized for cast iron chip control\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert accommodates both right-hand and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method ensures rigid, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eManufactured to M tolerance and N clearance code for consistent dimensional fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT T-Max P series toolholders that accept WNMG 08 04 insert seats.

Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully against the pocket locating surfaces before engaging the clamp and pin holding method, and verify seating is flush with no rocking before torquing the clamping screw. Follow the toolholder manufacturer's clamping torque specifications as printed on the toolholder documentation, as no torque value is specified in this product data.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG 08 04 12-KR 3210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (80-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KR\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2948 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inches (3\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\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\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5756691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734716875058,"sku":"5756691","price":325.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64f711dd97737b061b7bf2f3d004c68c.jpg?v=1788765813","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5756691-turning-insert-wnmg433-kr-3210","provider":"Voomi Supply","version":"1.0","type":"link"}
