It carries a multilayer CVD coating of TiCN and Al2O3 applied via MTCVD process, delivering high wear resistance on steel and cast iron workpieces. The insert measures 11.00 mm (0.4331 inches) in length with a 0.25-inch inscribed circle, a 0.0156-inch (1\/64-inch) corner radius, and a 0.0938-inch (3\/32-inch) thickness. With three cutting edges, a positive rake angle of 5 degrees, and a UF chip breaker geometry, this insert is engineered for finishing operations where tight tolerances and fine surface finishes are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes in turning, facing, and boring applications on steel and cast iron components. The KCP05 grade provides high wear resistance for steel (P-class) and moderate wear resistance with toughness for aluminum and non-ferrous materials (N-class). It is a screw-on style insert with positive side clearance, intended for use in compatible TPMT-style toolholders on production and job-shop turning centers. Maximum depth of cut is 1.25 mm (0.0492 inches), making it appropriate for light, precise finishing cuts rather than heavy roughing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTPMT110204 ISO \/ TPMT2151 ANSI insert code with 60-degree triangular shape and three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eMultilayer CVD coating (TiCN plus Al2O3) for high wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eUF chip breaker geometry optimized for finishing operations at light depths of cut\u003c\/li\u003e\n  \u003cli\u003ePositive rake (5 degrees) and positive side clearance reduce cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge stability and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring in a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPMT-style screw-on toolholders accepting a 0.25-inch (1\/4-inch) inscribed circle triangular insert with a 0.1102-inch (2.80 mm) hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-recommended screw torque procedure for the specific toolholder to avoid insert cracking or improper seating. Inspect the toolholder pocket and clamping screw for wear or damage before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMT2151\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMT110204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TPMT2151UF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP05\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 Shape\u003c\/strong\u003e: T - Triangle, 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.00 mm (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive, 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UF (Finishing)\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: 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\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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 (minimum order quantity: 5)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3746138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728299622706,"sku":"3746138","price":175.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07538b9cd007eaf94d065d15cf6b2a2a.jpg?v=1788690341","url":"https:\/\/voomisupply.com\/products\/kennametal-3746138-tpmt2151uf-kcp05-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
