It belongs to the A2 series and carries the KCU25 manufacturer grade, a PVD-applied AlTiN coating that provides thermal resistance and extended tool life in demanding cutting environments. The insert features a 2.2 mm cutting width (0.0870 inch), a neutral lead angle of 0 degrees, a 2-degree relief angle, and a CF chipbreaker geometry engineered to control chip flow during parting and grooving cuts. Machinists and CNC operators working in production turning environments rely on this insert for consistent, repeatable performance on grooving applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, cutoff, and parting operations in both production and job-shop turning environments. The CF chipbreaker geometry makes it appropriate for applications where chip control is critical, particularly in medium to finishing cuts. The KCU25 grade with AlTiN PVD coating is well-matched to ferrous materials and applications requiring wear resistance at elevated cutting temperatures. It is sold as a single insert per package with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA2 series single-end cutoff insert with 2.2 mm (0.0870 inch) cutting width\u003c\/li\u003e\n  \u003cli\u003eKCU25 carbide grade with PVD-applied AlTiN coating for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eCF chipbreaker geometry for controlled chip flow in grooving and parting operations\u003c\/li\u003e\n  \u003cli\u003eNeutral lead angle (0 degrees) with 2-degree relief angle for balanced cutting forces\u003c\/li\u003e\n  \u003cli\u003eC2 and C6 material grade classifications for broad application coverage\u003c\/li\u003e\n  \u003cli\u003eFull radius: No — flat-bottomed groove profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for A2 series cutoff and grooving toolholders accepting size code 2 inserts.

Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the appropriate torx or hex key torque wrench as specified by the toolholder manufacturer when seating the insert clamp — do not overtighten by hand. Verify insert seating and clamp contact before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.20 mm (0.0870 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees, Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 4111082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736122589490,"sku":"4111082","price":390.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08336d1255e759f2281465bac4e2bb43.jpg?v=1788776008","url":"https:\/\/voomisupply.com\/products\/kennametal-4111082-cutoff-insert-kcu25-carbide-2-2mm","provider":"Voomi Supply","version":"1.0","type":"link"}
