Designed for external and internal turning operations, this insert features a 55-degree diamond shape, a positive rake angle of 5 degrees, and a honed cutting edge for clean, consistent cuts. The screw-on holding method provides secure seating in compatible toolholders. With a 3\/8-inch inscribed circle and a 1\/64-inch corner radius, this insert is suited for light to moderate material removal in demanding cutting environments. It carries two cutting edges per insert and is rated for use across steel, stainless steel, superalloys, and titanium workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in CNC turning centers, manual lathes, and boring setups where wear resistance and edge consistency are critical. The LF chip breaker geometry promotes controlled chip evacuation during turning, facing, boring, back turning, and back boring operations. The KC5010 grade with TiAlN PVD coating is specifically engineered for harder-to-machine materials including stainless steel, superalloys, and titanium, making it a practical choice for aerospace, medical, and precision manufacturing applications. The neutral hand orientation supports a wide range of toolholder configurations. Sold individually, with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5010 carbide grade with PVD TiAlN coating for extended tool life in steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DCMT style) with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry supports turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for consistent performance and edge integrity\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for repeatable seating and quick indexing\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eComplies with ANSI and ISO insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard DCMT-style insert for screw-on turning toolholders accepting a 3\/8-inch inscribed circle diamond insert. Industry standard number DCMT3251LF. Compatible with toolholders rated for DCMT-style inserts per ANSI and ISO standards.

Ensure the machine spindle is fully stopped and the turret is de-energized before indexing or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to seat the clamping screw to proper engagement without stripping the insert pocket. Inspect the insert pocket and seating surfaces for chips or wear before installing a new insert to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DCMT3251LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\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\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 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 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: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 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\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\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\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\u003eWeight\u003c\/strong\u003e: 0.011 pounds\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\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: 1310890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747231236402,"sku":"1310890","price":169.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/656e17c7eac98921a2fda33f27f1a0c4.jpg?v=1788877795","url":"https:\/\/voomisupply.com\/products\/kennametal-1310890-turning-insert-dcmt3251lf-kc5010","provider":"Voomi Supply","version":"1.0","type":"link"}
