The insert features a multilayer CVD coating — TiN, Al2O3, and MT-TiCN — applied over a carbide substrate to extend tool life in demanding cutting applications. It carries a diamond (80-degree) insert shape with a negative rake angle, a chamfered and honed cutting edge style, and four usable cutting edges per insert. The 0.0313-inch corner radius and KENLOC series geometry make this a practical choice for general-purpose metal removal where consistent edge performance is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for machining steel and cast iron workpieces in both roughing and semi-finishing passes. The CNMG542RN chip breaker geometry and neutral hand orientation allow installation in a wide range of CNMG-compatible toolholders used in CNC turning centers and manual lathes. The 80-degree diamond shape provides strong edge support while allowing reasonable clearance in profiling cuts. Licensed machinists, toolroom technicians, and CNC operators are the primary users. With a maximum depth of cut of 0.2113 inches, this insert is well-matched to medium-duty turning applications where steel and cast iron are the primary materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiN outer layer, Al2O3 intermediate layer, MT-TiCN base layer for wear and crater resistance\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative rake for strong edge support\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style reduces microchipping on entry\u003c\/li\u003e\n  \u003cli\u003eKENLOC series geometry with RN chip breaker suits turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method compatible with standard CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style indexable toolholders compatible with the KENLOC series.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque on the clamping screw as specified by the toolholder manufacturer — do not overtighten, as this can crack the insert or damage the pocket seat. Inspect the insert pocket and locating pin for debris or wear before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG542RN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160608RN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiN, Al2O3, MT-TiCN (multilayer)\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: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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: Chamfered and 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\u003eInsert Length\u003c\/strong\u003e: 0.6346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6250 inches (5\/8 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: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2113 inches\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 Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\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\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\u003eWeight\u003c\/strong\u003e: 0.05 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: 7026645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755144315186,"sku":"7026645","price":230.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1db06280e18474424e5bf4d9ad0db485_a49dc16c-0962-445a-85d1-fd634e9bdf34.jpg?v=1788951517","url":"https:\/\/voomisupply.com\/products\/kennametal-7026645-cnmg542rn-kcp25c-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
