Graded KCK20B and finished with a multilayer MTCVD coating sequence of TiCN, Al2O3, and TiOCN, this insert delivers wear resistance and thermal stability when cutting steel and cast iron. The 80-degree diamond shape provides a strong cutting edge geometry, and the honed cutting edge style promotes consistent, repeatable surface finishes. Four usable cutting edges maximize tool life per insert. It is sized at 0.5077 inches in length with a 0.5-inch inscribed circle and a 1\/32-inch corner radius.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations in production and job-shop environments. It is commonly used on ferrous workpieces classified under ISO material groups P (steel) and K (cast iron), making it a practical choice for general-purpose lathe work across both roughing and finishing passes within its rated depth-of-cut range. The flat-top chip breaker geometry and negative rake angle make it especially effective on interrupted cuts and tough steel alloys where edge security is a priority. Licensed machinists and CNC operators in metalworking trades are the primary installers and users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCK20B grade with multilayer CVD coating: TiCN base, Al2O3 mid-layer, TiOCN outer layer for high wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCNMA432 geometry with 80-degree diamond shape and negative rake for strong, secure cutting edge\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1691 inches suits both roughing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods in KENLOC-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept CNMA432 inserts with clamp and pin holding.

Power down and lock out the machine spindle before seating or indexing inserts. Ensure the insert pocket and seating surfaces are clean and free of chips before clamping to prevent microfracture at the cutting edge. Torque clamping hardware to toolholder manufacturer specifications and verify insert seating visually before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMA120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN, Al2O3, TiOCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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 Length\u003c\/strong\u003e: 12.9 mm (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: 0.0313 inches (1\/32 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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: 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, Cast Iron\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2557 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5641360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747785015602,"sku":"5641360","price":180.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba5e8fa8b849278003d35ea8c0525606_206b30f3-cd04-4733-896d-25ac960e3740.jpg?v=1788885454","url":"https:\/\/voomisupply.com\/products\/kennametal-5641360-cnma432-kck20b-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
