It is an 80-degree trigon-shaped insert belonging to the KENLOC series, designed for external and internal turning, facing, and boring operations on CNC and manual lathes. The insert features a negative rake angle of 13 degrees, a neutral hand, and a honed cutting edge for consistent engagement. With six available cutting edges per insert and an MS chip breaker geometry, it targets roughing to medium machining passes. The inscribed circle measures 0.5 inches with a corner radius of 0.0156 inches (1\/64 inch).\u003c\/p\u003e\u003cp\u003eThis insert is suited for machining steel, stainless steel, cast iron, superalloys, and titanium across a range of material grades including C3 and C4 carbide classifications. The KCU10 grade delivers high wear resistance combined with moderate toughness, making it effective in applications where tool life and edge stability are priorities. It is used in job shops and production environments where consistent chip control across roughing and medium cuts is required. The maximum depth of cut reaches 0.200 inches (5.08 mm), supporting aggressive stock removal in production turning setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 grade with TiAlN PVD coating for wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree trigon insert shape (WNMG) with negative rake and negative side clearance\u003c\/li\u003e\n\u003cli\u003eMS chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for controlled engagement and reduced chipping risk\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods in KENLOC-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting WNMG431 (ISO WNMG080404) inserts with clamp or pin retention.

Ensure the machine spindle is fully stopped and all axes are at a safe position before indexing or replacing inserts. Seat the insert fully against the pocket walls and apply the appropriate clamping torque per the toolholder manufacturer specification using the correct Torx or hex key. Inspect the insert pocket and clamp for wear or debris before seating a new edge to prevent insert rocking and premature failure.\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\u003eIndustry Standard Number\u003c\/strong\u003e: WNMG431MS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\u003eChip Breaker\u003c\/strong\u003e: MS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6840 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: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.200 inches (5.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.02 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5090893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731852099890,"sku":"5090893","price":185.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b15a57d2be2f7f9f2395bd0417dbee6b.jpg?v=1788735610","url":"https:\/\/voomisupply.com\/products\/kennametal-5090893-wnmg431ms-kcu10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
