It features a 55-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and an 11-degree relief angle. The insert is PVD-coated with TiAlN for moderate wear resistance and toughness across a range of workpiece materials. With a 0.25-inch inscribed circle, a 0.0156-inch corner radius, and an overall length of 7.75 mm (0.6104 inches), this insert is sized for finishing and light machining operations. It is held in the toolholder via a screw-on method and provides two usable cutting edges per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for CNC turning, facing, boring, back turning, and back boring applications in both production and job-shop environments. Primary workpiece materials include stainless steel and superalloys and titanium, with additional suitability for steel, cast iron, and aluminum and non-ferrous materials as indicated by workpiece material codes P, M, K, N, and S. The LF chip breaker geometry is optimized for finishing and light machining passes, making this insert appropriate for close-tolerance work where surface finish and dimensional accuracy are critical. Machinists and CNC operators working with difficult-to-machine alloys will find the KC5025 grade a practical choice for moderate wear resistance paired with adequate toughness.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55-degree diamond insert shape (DPMT style) with positive rake for free-cutting action\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating on solid carbide substrate for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry engineered for finishing and light machining\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert, screw-on holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inches) supports precision stock removal\u003c\/li\u003e\n  \u003cli\u003eMulti-use capability across turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for screw-on style DPMT toolholders conforming to ANSI and ISO standards.

Always index or replace inserts with the machine in a safe, powered-down or locked-out state per your facility lockout\/tagout procedure. Use the correct torque wrench and manufacturer-specified screw to seat the insert without cracking the carbide. Inspect the insert pocket for chips or debris before seating a new or indexed insert to ensure full, flat contact and accurate positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DPMT2151\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DPMT070204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DPMT2151LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 7.75 mm (0.6104 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\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\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\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorkpiece Material Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back 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\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: 2425791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740971335986,"sku":"2425791","price":185.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec2773e8374fb86de3f59575815fcf1a_cd5ee9af-1d0b-4d43-8324-3a710ec4f003.jpg?v=1788828683","url":"https:\/\/voomisupply.com\/products\/kennametal-2425791-turning-insert-dpmt2151lf-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
