It features a multilayer CVD coating of TiCN and Al2O3 applied via MTCVD process, delivering a balance of moderate wear resistance and toughness suited to steel and cast iron workpieces. The insert measures 11 millimeters in length with a 0.25 inch inscribed circle diameter, a 0.0938 inch thickness, and a 1\/32 inch corner radius. Three cutting edges are available per insert. The LF chip breaker geometry is optimized for finishing and light machining passes. A licensed HVAC or machining technician installs this as part of a screw-on toolholder system.\u003c\/p\u003e\n\u003cp\u003eThis insert is built for turning, facing, and boring operations across steel and aluminum or non-ferrous materials. The positive rake angle of 5 degrees and honed cutting edge style reduce cutting forces during light finishing cuts, making it well suited to close-tolerance work on steel (ISO material group P) and aluminum or non-ferrous (ISO material group N) components. It conforms to ANSI insert code TPMT2152 and ISO insert code TPMT110208, and fits standard TPMT screw-on toolholders used in production turning centers and manual lathes in job shop and production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP25 grade with multilayer CVD TiCN and Al2O3 coating for wear resistance and toughness on steel and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry designed for finishing and light machining operations\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (5 degrees) and honed cutting edge reduce cutting forces and improve surface finish\u003c\/li\u003e\n  \u003cli\u003eThree usable cutting edges per insert maximizes tool economy\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method ensures secure seating and repeatable edge indexing\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-compatible replacement conforming to ANSI insert code TPMT2152 and ISO insert code TPMT110208.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque screwdriver or insert key to secure the screw-on fastener  -  do not overtighten, as this can crack the carbide substrate. Inspect the toolholder pocket for chips or debris before seating a new edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMT2152\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMT110208\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11 millimeters (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees positive\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 millimeters (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron (P); Aluminum and Non-Ferrous (N)\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\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 3751604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739926036786,"sku":"3751604","price":202.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16afcdfbcdec3871c3878f1456083a4d_d79aec5d-dd7f-4bc4-be81-3266f8218d86.jpg?v=1788820445","url":"https:\/\/voomisupply.com\/products\/kennametal-3751604-tpmt2152lf-kcp25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
