Coated with TiAlN via a PVD process, this insert is engineered for high wear resistance across a range of workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. It features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a negative rake and side clearance geometry. With a 0.5-inch inscribed circle and a 0.0156-inch corner radius, it suits medium machining chip breaker applications. Four cutting edges per insert maximize tool life. Licensed machinists and CNC turning specialists are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on lathes and turning centers handling steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous materials (N), superalloys and titanium (S), and hardened materials (H). The KCU10 grade targets high to moderate wear resistance combined with appropriate toughness for interrupted and continuous cuts in production environments. It is a fit for shops running medium machining operations where consistent edge performance across material families is a priority. The KENLOC clamping system, using a clamp and pin holding method, is required for proper seating and secure insert retention during operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating delivers high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape provides a strong cutting edge with good versatility\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping at the edge during entry and exit\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance geometry compatible with rigid, clamp-and-pin toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use designation supports turning, facing, and boring in a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept CNGP431 (ANSI) or CNGP120404 (ISO) inserts with a clamp and pin holding method.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert. Follow applicable shop safety protocols and machine guarding requirements during insert changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGP431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGP120404\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: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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 Thickness\u003c\/strong\u003e: 0.1875 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\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: 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: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Medium Machining\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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 per package (minimum order quantity: 5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0218 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: 4050673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749255414066,"sku":"4050673","price":234.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d494b5ef4a754cf53087510a19e615e6_59cd03d2-7219-4386-803c-36b6e3477a4b.jpg?v=1788903657","url":"https:\/\/voomisupply.com\/products\/kennametal-4050673-cngp431-kcu10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
