Built to grade ACP15K with a CVD coating, it delivers high wear resistance across a range of workpiece materials including steel, stainless steel, and cast iron. The trigon 80-degree W-shape with a neutral hand orientation and negative side clearance provides stable cutting geometry. With 6 usable cutting edges per insert, it extends tool life and reduces per-edge cost in production environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for general-purpose turning in job shop and production environments handling steel (P-code), stainless steel (M-code), and cast iron (K-code) workpieces. The WM+ chip breaker geometry supports moderate to high material removal rates while managing chip control across varying feed rates and depths. Maximum depth of cut is 0.1575 inches (4.00 mm), making it appropriate for semi-finishing and medium roughing passes. Machinists and CNC programmers specify this insert for turning toolholders requiring WNMG-style inserts with clamp, lever lock, pin, or screw holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade ACP15K CVD-coated carbide substrate for wear resistance on steel, stainless, and cast iron\u003c\/li\u003e\n\u003cli\u003eWNMG431 \/ WNMG080404 geometry with 80-degree included angle and W trigon insert shape\u003c\/li\u003e\n\u003cli\u003e6 cutting edges per insert for extended tool life and reduced tooling cost per edge\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker for effective chip control in semi-finishing and medium roughing applications\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, lever lock, pin, and screw insert-holding methods\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0157 inches (0.40 mm) for controlled surface finish and edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style indexable replacement for toolholders accepting WNMG431 or WNMG080404 style turning inserts with a negative rake seat and 0.2043-inch hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the pocket locating surfaces and torque the clamping screw or lever to the toolholder specification. Inspect the insert pocket and seating surface for chips or debris before installing a fresh cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: WNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: WNMG080404\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: W - Trigon 80-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP15K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1575 inches (4.00 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Lever Lock, Pin, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P (Steel), M (Stainless Steel), K (Cast Iron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75257071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732252721458,"sku":"75257071","price":191.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f50dbaab3c913764c17a8de767140031_6e8a3d68-9f03-48e9-aeb7-bbb24bb07497.jpg?v=1788740863","url":"https:\/\/voomisupply.com\/products\/accupro-75257071-wnmg431-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
