It carries the ANSI insert code DCMT3251FP and ISO designation DCMT11T304, with a 55-degree diamond (rhombic) shape and a screw-on holding method. The insert is PVD-coated with AlTiN for high wear resistance across a broad range of workpiece materials. With a 3\/8 inch inscribed circle, a 1\/64 inch corner radius (0.0156 inches), and a positive rake geometry, it is optimized for light, high-precision cuts. Machinists and CNC operators in production and job shop environments install this insert in compatible screw-on toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing passes in turning, facing, boring, back turning, and back boring applications. It performs across multiple material categories including steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous materials (N), superalloys and titanium (S), and hardened materials (H). The KCS10 grade is engineered to deliver high wear resistance with moderate toughness, making it a practical choice for demanding finishing work on difficult-to-machine alloys and stainless steel. The FP chip breaker geometry supports controlled chip formation at finishing parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating provides high wear resistance for extended tool life on steel, stainless, and superalloys\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with positive rake angle (15 degrees) for low cutting forces and clean surface finish\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry optimized for finishing operations with controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for secure, repeatable seating in the toolholder pocket\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert; neutral hand orientation for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.0492 inches (1.25 mm), appropriate for light finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on style DCMT toolholders conforming to ANSI and ISO standards for DCMT3251 and DCMT11T304 insert seats.

Power down and lock out the spindle before changing inserts. Use the manufacturer-specified torque wrench and clamp screw to seat the insert; do not use standard hex keys at uncontrolled torque, as over-tightening can fracture the carbide. Inspect the pocket seat and clamp screw threads for wear or contamination before installing a fresh insert to ensure proper seating and accurate tool-nose position.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55-Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCS10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP (Finishing)\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.63 mm (0.9156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eRake Angle\u003c\/strong\u003e: 15 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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 Materials\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium (P, M, K, N, S, H)\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 (MOQ 5)\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: 3769359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744952451378,"sku":"3769359","price":170.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a10518c618a09947dc881699a2466654.jpg?v=1788862626","url":"https:\/\/voomisupply.com\/products\/kennametal-3769359-dcmt3251fp-kcs10-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
