It features an 80-degree diamond (rhombic) shape, a 1\/4-inch inscribed circle, and a 1\/64-inch corner radius (0.0156 inches). The insert carries a multilayer MTCVD coating — TiCN, Al2O3, and TiOCN — engineered for moderate wear resistance and toughness on steel and cast iron. With a positive rake angle of 15 degrees and a positive side clearance, this insert is configured for finishing operations. It is held by a screw-on method and is suited for CNC turning centers and manual lathes in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring applications. Its FP chip breaker geometry is optimized for finishing passes on steel and cast iron workpieces, including P-grade and N-grade materials. The neutral hand orientation allows use in a range of toolholders. Maximum depth of cut is 0.0845 inches, making it appropriate for light to moderate material removal where surface finish and dimensional accuracy are the priority. Machinists and CNC operators in production shops, maintenance facilities, and contract machining environments will find this insert well suited to finish-turning steel and cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI insert code CPMT2151FP; ISO insert code CPMT060204\u003c\/li\u003e\n  \u003cli\u003eKCP25B grade with multilayer MTCVD coating: TiCN, Al2O3, TiOCN\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond shape with 11-degree relief angle and 15-degree positive rake\u003c\/li\u003e\n  \u003cli\u003eFP chip breaker geometry for finishing operations\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges; neutral hand; screw-on holding method\u003c\/li\u003e\n  \u003cli\u003eRated for turning, facing, and boring on steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CPMT-style screw-on toolholders accepting a 1\/4-inch inscribed circle, 3\/32-inch thick diamond insert.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the appropriate torx or hex key to fasten the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten. Inspect the seating pocket and chip breaker contact surfaces for debris before inserting to ensure proper support and repeatable tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT2151FP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT060204\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: KCP25B\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: TiCN, Al2O3, TiOCN (Multilayer MTCVD CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2539 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0845 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP - Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\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\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5537429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732881670450,"sku":"5537429","price":185.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceab44dc84c9d19479517ca6255751a3_db485807-df24-4f81-9555-d5e008a3965e.jpg?v=1788747948","url":"https:\/\/voomisupply.com\/products\/kennametal-5537429-cpmt2151fp-kcp25b-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
