The insert features a 60-degree triangular shape with a positive rake angle, positive side clearance, and an MF chip breaker geometry optimized for finishing and medium machining operations. The inscribed circle measures 3\/8 inches (0.3750 inches), the corner radius is 1\/32 inches (0.0313 inches), and overall insert length is 0.6496 inches (16.50 mm). Three cutting edges are available per insert. This insert is intended for use by machinists and CNC operators running turning, facing, and boring operations on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThe KENNAMETAL 3753431 is suited for turning steel, cast iron, aluminum, and other non-ferrous materials in both light finishing passes and moderate medium-machining cuts. The KCP25 grade delivers a balance of wear resistance and toughness appropriate for steel (ISO P workpieces) and non-ferrous materials (ISO N workpieces). Maximum depth of cut is 1.25 mm (0.0492 inches). The MF chip breaker geometry supports controlled chip formation at tighter depths of cut and feed rates typical of finishing work. This insert applies equally to manual lathe work and programmed CNC turning cycles where consistent surface finish is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTPMT triangular insert shape with 60-degree included angle and three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eKCP25 carbide grade with multilayer CVD TiCN and Al2O3 coating for wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry engineered for finishing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance reduce cutting forces on steel and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method with chamfered and honed cutting edge style for edge stability\u003c\/li\u003e\n  \u003cli\u003eConforms to both ANSI (TPMT3252) and ISO (TPMT16T308) insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on TPMT-style toolholders conforming to ANSI and ISO insert seating standards.

Seat the insert fully into the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque. Inspect the seating face and chip breaker for debris before securing the insert. Verify insert orientation and cutting edge selection before resuming machine operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMT3252\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMT16T308\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\u003eManufacturer Grade\u003c\/strong\u003e: KCP25\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches (16.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: 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\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\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, Aluminum, 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\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\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: 0.1 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: 3753431\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739840708914,"sku":"3753431","price":235.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3ff813a3be8223ec043613460184133.jpg?v=1788819460","url":"https:\/\/voomisupply.com\/products\/kennametal-3753431-tpmt3252mf-kcp25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
