The insert features a PVD-applied TiAlN coating that delivers high wear resistance across a broad range of cutting conditions. Key geometry details include an 80-degree diamond (rhombic) shape, a 0.0156-inch corner radius, a 0.5-inch inscribed circle, and a neutral hand orientation. With four usable cutting edges and a negative rake configuration, this insert is suited for moderate to heavy material removal in production turning environments. It is installed and managed by machinists, tooling engineers, and CNC operators.\u003c\/p\u003e\u003cp\u003eThis insert is intended for roughing and medium machining operations. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium, corresponding to ISO material codes P, M, K, N, S, and H. The KENLOC series designation indicates compatibility with KENNAMETAL KENLOC-style toolholders that accept CNMG-style inserts with clamp or pin holding methods. The RP chip breaker geometry is optimized for roughing and medium cuts, providing controlled chip flow across a wide range of depths of cut and feed rates. This insert conforms to both ANSI and ISO standards, with ANSI code CNMG431 and ISO code CNMG120404RP.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN (PVD) coating provides high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with negative rake and neutral hand for versatile positioning\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert reduce per-edge tooling cost in production runs\u003c\/li\u003e\n\u003cli\u003eRP chip breaker suited for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style balances edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL KENLOC-series toolholders accepting CNMG431 (ANSI) or CNMG120404 (ISO) inserts with clamp or pin insert holding.

Seat the insert firmly against the pocket locating surfaces before engaging the clamping mechanism, and inspect the pocket for chips or debris before each index. Do not exceed the maximum depth of cut of 0.1691 inches without consulting applicable toolholder and workpiece material guidelines. Cutting parameters should be established using the toolholder manufacturer's recommended speeds and feeds for the KCU10 grade and target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404RP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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\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\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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\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\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\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\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\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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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\u003eWeight\u003c\/strong\u003e: 0.022 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 4050682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732860305714,"sku":"4050682","price":182.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dab51e2a129ff0134e1b245ca67fc47_59b1dcb5-4ed6-4c0f-af39-d8d319b6b9f4.jpg?v=1788747641","url":"https:\/\/voomisupply.com\/products\/kennametal-4050682-turning-insert-cnmg431rp-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
