The insert features a PVD-applied TiAlN coating over a solid carbide substrate, combining high wear resistance with thermal stability during aggressive cuts. With an 80-degree diamond (rhombic) shape and a 0.0625-inch corner radius, it delivers consistent edge geometry across four usable cutting edges. The RP chip breaker geometry targets roughing and medium machining applications. A licensed machinist or CNC operator installs this insert as part of a KENLOC tooling system using a clamp-and-pin holding method.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring on steel, stainless steel, cast iron, superalloys, and titanium workpieces. The KCU10 grade provides a balance of high wear resistance and toughness appropriate for P (steel), M (stainless steel), K (cast iron), N (non-ferrous), S (superalloys and titanium), and H (hardened materials) workpiece material groups. It is a neutral-hand insert, making it adaptable to both right- and left-hand toolholders. The RP chip breaker is optimized for roughing to medium depth-of-cut ranges, helping manage chip flow and reduce cutting forces in interrupted or continuous cuts on challenging materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG434 ANSI geometry with 80-degree diamond insert shape and negative rake angle for robust edge support\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating provides high wear resistance and thermal performance in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eRP chip breaker optimized for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges maximize insert utilization and reduce per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eNeutral hand configuration compatible with both right- and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp-and-pin holding method compatible with KENLOC series toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders that accept CNMG434 inserts with clamp-and-pin holding.

Before indexing or replacing inserts, ensure the machine spindle is fully stopped and the toolholder is secured in the turret. Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert — do not hand-tighten clamp screws without a torque tool. Inspect the insert pocket and seating surfaces for chips or debris before installing a fresh edge to maintain correct insert geometry and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG434\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120416\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG434RP\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\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\u003eInsert Length\u003c\/strong\u003e: 0.5077 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RP (Roughing \/ Medium Machining)\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Negative)\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 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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous, Superalloys and Titanium, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: 0.0215 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 4050699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733651489074,"sku":"4050699","price":182.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dab51e2a129ff0134e1b245ca67fc47_046c6e06-1585-4790-bcc9-eb1a28461793.jpg?v=1788757519","url":"https:\/\/voomisupply.com\/products\/kennametal-4050699-turning-insert-cnmg434rp-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
