It belongs to the KENLOC series and is engineered for high wear resistance when cutting steel and cast iron. The insert measures 8.69 mm (0.684 inches) in length with a 0.5-inch inscribed circle and a 1\/32-inch (0.0313-inch) corner radius. With six cutting edges and a neutral hand orientation, it delivers consistent performance across roughing and medium machining operations. Licensed HVAC and metalworking professionals select this insert for demanding turning, facing, and boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use on CNC lathes and turning centers in both roughing and medium machining passes on steel (ISO P) and cast iron (ISO K) workpieces. The RP chip breaker geometry is optimized for controlled chip evacuation during moderate to heavy material removal. The 80-degree trigon shape provides a strong cutting edge with adequate relief geometry for a wide range of turning applications. The insert is held in place by clamp or pin methods, making it compatible with standard KENLOC toolholders designed for WNMG-style inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCK20 grade with multilayer AlTiN\/AlCrN PVD coating for high wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eWNMG432RP geometry: 80-degree trigon, negative rake, negative clearance (N tolerance, M tolerance code)\u003c\/li\u003e\n\u003cli\u003eSix usable cutting edges per insert for extended tool life and reduced cost per edge\u003c\/li\u003e\n\u003cli\u003eRP chip breaker designed for roughing and medium machining chip control\u003c\/li\u003e\n\u003cli\u003ePVD coating process preserves sharp edge geometry, including chamfered and honed cutting edge style\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods for secure seating under interrupted or heavy cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC series toolholders that accept WNMG432 (ANSI) or WNMG080402 (ISO) style inserts with clamp or pin holding.

Use the appropriate torque wrench and KENLOC clamp hardware specified for the toolholder to seat the insert correctly. Inspect the insert pocket for wear, chips, or debris before seating a new insert. Never use a damaged or improperly seated insert, as it can cause insert fracture or workpiece damage during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: WNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: WNMG080402\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN \/ AlCrN Multilayer PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 8.69 mm (0.684 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RP\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\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron (K)\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\u003ePackage Weight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3753912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740838986034,"sku":"3753912","price":185.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e375e4858bda5647a6c26bc19ab5767.jpg?v=1788827763","url":"https:\/\/voomisupply.com\/products\/kennametal-3753912-wnmg432rp-kck20-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
