The insert features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, delivering wear resistance and thermal stability during continuous and interrupted cuts. It carries a 0.5 inch inscribed circle, a 0.0472 inch (3\/64 inch) corner radius, and an 80-degree trigon shape with a negative rake geometry. The MF4 chip breaker geometry and chamfered-and-honed cutting edge make it well suited for finishing and light roughing applications. Six usable cutting edges per insert reduce per-edge tooling cost. Licensed machinists and CNC operators install and index these inserts.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily rated for stainless steel (ISO material code M) and is secondarily suited for steel (ISO material code P). Recommended material grades are M25, M30, and M35. The WNMG433-MF4 geometry supports boring, facing, and turning operations, making it a versatile single-insert choice for shops running stainless and steel components in both low-volume job shop and high-production environments. The neutral hand orientation means it seats in standard WNMG-compatible toolholders without handedness restrictions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic TiCN\/Al2O3\/Cr multilayer coating for extended tool life on stainless steel and steel\u003c\/li\u003e\n  \u003cli\u003eMF4 chip breaker geometry optimized for finishing and light roughing passes\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges per insert maximizes value per unit\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for stable entry and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 80-degree trigon shape with N clearance and M tolerance per ANSI and ISO standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert-holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WNMG-style toolholders that accept a 1\/2 inch inscribed circle trigon insert with clamp, pin, or lever-lock holding methods.

Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate torque wrench and manufacturer-specified fasteners when securing the clamping screw or lever-lock pin to avoid cracking the insert or damaging the pocket seating surface. Inspect the toolholder pocket for wear, chips, or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: WNMG433-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: WNMG080412-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TM2501\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (3\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6842 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3248 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\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: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code N)\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF4\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: TiCN \/ Al2O3 \/ Cr (Duratomic CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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 Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M25, M30, M35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03273970\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562552590642,"sku":"03273970","price":37.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2f3212a9244016cd38ee28d9ebf1277_af72a858-6b12-4a97-81bb-b9bcddaef994.jpg?v=1786479550","url":"https:\/\/voomisupply.com\/products\/seco-03273970-wnmg433-mf4-tm2501-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
