It carries the form designation A4C0205N00CF02 and is manufactured in the KCU25 grade with an AlTiN coating applied via PVD process. The insert features a 2.05 mm (0.0807 inch) cutting width, a neutral lead angle, and a CF chipbreaker geometry. A 2-degree relief angle and a 0.0079-inch corner radius support consistent chip formation and edge stability during cutoff work. Licensed machinists and CNC operators install this insert into compatible A4-series clamp-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for cutoff and grooving applications in medium to high production turning environments. The A4 series double-end design allows both ends of the insert to be used, extending service life between changes. The KCU25 PVD-AlTiN coating provides wear resistance and thermal stability, making it appropriate for machining steel, stainless steel, and similar workpiece materials. The CF chipbreaker geometry is optimized for controlled chip evacuation in moderate feed-rate grooving passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.05 mm (0.0807 inch) cutting width with neutral lead angle and 0-degree lead angle setting\u003c\/li\u003e\n  \u003cli\u003eKCU25 carbide grade with PVD-applied AlTiN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCF chipbreaker geometry promotes chip control in grooving and cutoff operations\u003c\/li\u003e\n  \u003cli\u003eDouble-end insert design maximizes usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with A4-series toolholders\u003c\/li\u003e\n  \u003cli\u003e0.0079-inch corner radius with 2-degree relief angle for stable edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in A4-series clamp-style cutoff and grooving toolholders that accept insert seat size 2.

The machine spindle must be stopped and all motion fully arrested before changing inserts. Seat the insert fully against the toolholder pocket and confirm the clamp is secured to the manufacturer torque specification listed in the toolholder documentation. Inspect the insert seat for chips or debris before seating a new insert to prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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\u003eCutting Width\u003c\/strong\u003e: 2.05 mm (0.0807 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20.02 mm (0.7880 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.09 mm (0.1610 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 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: 4113711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747919626546,"sku":"4113711","price":588.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4819660a5996fa5730998a5a98a19c9.jpg?v=1788887076","url":"https:\/\/voomisupply.com\/products\/kennametal-4113711-cutoff-insert-kcu25-carbide-2-05mm","provider":"Voomi Supply","version":"1.0","type":"link"}
