It features a multilayer CVD coating of TiCN and Al2O3 applied via MTCVD process, delivering moderate wear resistance and toughness suited to steel, cast iron, aluminum, and non-ferrous materials. The insert measures 6.45 mm (0.2539 inches) in length with a 0.25-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius. The LF chip breaker geometry is optimized for finishing and light machining cuts. Licensed machinists and CNC operators install this insert in screw-on style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited to finishing and light machining passes on steel and cast iron workpieces, as well as aluminum and non-ferrous materials in both primary material code P and N applications. The 80-degree diamond (rhombic) shape provides good nose strength for general turning and facing passes. The positive rake angle of 5 degrees and positive side clearance support clean chip formation at lighter depths of cut, with a maximum depth of cut of 1.25 mm (0.0492 inches). The neutral hand orientation and screw-on mounting method make it compatible with a wide range of CPMT-style toolholders used in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25 grade with MTCVD multilayer TiCN and Al2O3 coating for wear resistance and toughness on steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (C-shape) insert geometry with positive rake and positive side clearance for clean, low-force cuts\u003c\/li\u003e\n\u003cli\u003eLF chip breaker designed for finishing and light machining applications\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius (0.0156 inches) for tight-tolerance finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method with honed cutting edge style for consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; neutral hand suits standard CPMT screw-on toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CPMT-style screw-on turning toolholders conforming to ANSI insert code CPMT2151 and ISO insert code CPMT060204.

Power down and de-energize the machine before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specification; do not overtighten, as this can crack the insert. Inspect the toolholder pocket and clamping screw for wear or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT2151\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT060204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CPMT\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: KCP25\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 and Al2O3 (Multilayer CVD - MTCVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.45 mm (0.2539 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 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\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: 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: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and Non-Ferrous\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 3751577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740423192882,"sku":"3751577","price":185.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c365302a32ff086fefb431ab09c517e5.jpg?v=1788824916","url":"https:\/\/voomisupply.com\/products\/kennametal-3751577-cpmt2151lf-kcp25-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
