Built from solid carbide with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert delivers wear resistance and thermal stability across a range of turning operations. The trigon (W) insert shape provides an 80-degree included angle and six usable cutting edges per insert. A 1\/32-inch corner radius and neutral hand orientation make it a versatile choice for finish and semi-finish turning. Machinists and CNC operators install this insert into compatible T-Max P toolholders as part of a high-productivity external turning setup.\u003c\/p\u003e\u003cp\u003eThis insert is optimized for primary use on cast iron workpiece materials (ISO material code K). The KF chip breaker geometry is suited for finishing and light semi-finishing passes where controlled chip formation and consistent surface finish are required. With a maximum depth of cut of 7.89 mm and an inscribed circle of 0.5000 inches (12.70 mm), it fits standard WNMG 08 04 08 toolholder pockets. It is held in place using a clamp and pin method, which is standard for this insert style. The ISO designation for this insert is WNMG 08 04 08-KF 3210.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and heat management\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eKF chip breaker geometry engineered for finishing passes on cast iron\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both left- and right-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method provides secure seating under interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eTolerance code M and clearance code N per ISO insert classification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in WNMG 08 04 08 toolholder pockets within the SANDVIK COROMANT T-Max P turning system.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten the clamp screw, as this can chip the insert or damage the pocket seat. Inspect the pocket seat and locating pin for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG 08 04 08-KF 3210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (W), 80-degree included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 7.89 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Rounded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (clearance code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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: Cast Iron (ISO code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.54 inches x 1 inch x 0.19 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6868515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744862667058,"sku":"6868515","price":282.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6d3308c91936c75057ab03345ac4d17_c1338b40-2184-4145-8dd8-51a6cecbe24f.jpg?v=1788861689","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6868515-turning-insert-wnmg432-kf-3210","provider":"Voomi Supply","version":"1.0","type":"link"}
