The insert features an 80-degree diamond (rhombic) shape, a negative rake angle of 12 degrees, and a honed cutting edge style suited to finishing operations. With four usable cutting edges, a 0.5000-inch inscribed circle, and a 0.0156-inch corner radius, it is engineered for high wear-resistance across steel, stainless steel, cast iron, and superalloy workpiece materials. Licensed machinists and CNC turning specialists select this insert for precision finishing passes where surface finish and dimensional control are the priority.\u003c\/p\u003e\n\u003cp\u003eThis insert is part of the KENNAMETAL KENLOC series and is designed for turning, facing, and boring applications. Its primary workpiece material classifications span P, M, K, N, S, and H material codes, making it applicable to steel, stainless steel, cast iron, aluminum, superalloys, and hardened materials. The FS chip breaker geometry is optimized for finishing cuts, and the negative side clearance geometry provides a robust edge suited to rigid insert-holding setups using clamp and pin methods. Maximum depth of cut is 0.1691 inches, keeping the insert in its intended light-to-moderate material removal range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNGG431FS geometry with 80-degree diamond shape and negative rake for stable finishing cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating under KCS10B grade delivers high wear-resistance on stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert reduce cost-per-edge in production turning\u003c\/li\u003e\n  \u003cli\u003eFS chip breaker optimized for finishing operations with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style minimizes micro-chipping on difficult materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods for secure seating in CNGG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGG-style insert toolholders that accept a 431 ANSI size code (ISO size code 120404) with clamp and pin holding.

Always power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp or pin to prevent micromovement during cutting. Inspect the insert pocket for chips or wear debris that could affect seating; a contaminated pocket will compromise edge life and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGG120404FS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCS10B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FS (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: 0.5077 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 12 degrees (Negative)\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium, Steel, Cast Iron, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02423 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6756003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727252980018,"sku":"6756003","price":55.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a04b96aebf13f6618db962e2118d183d.jpg?v=1788675465","url":"https:\/\/voomisupply.com\/products\/kennametal-6756003-cngg431fs-kcs10b-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
