It belongs to the A2 series and carries the KCU25 manufacturer grade with an AlTiN coating applied via PVD process. The insert delivers a 4 mm cutting width and a neutral lead angle with a 2-degree relief angle, making it well suited for general-purpose cutoff work on steel, cast iron, and similar materials. A CM chipbreaker geometry helps control chip flow during through-cuts. Licensed machinists and CNC turning specialists are the typical installers of this tooling component.\u003c\/p\u003e\n\u003cp\u003eThis insert is appropriate for residential shop, job shop, and production machining environments where reliable parting and cutoff performance is required on a turning center or manual lathe equipped with an A2-series insert holder. The clamp-style holding method secures the insert firmly in compatible A2 toolholders. The neutral hand orientation allows use in standard right-hand or centerline cutoff applications. It is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with KCU25 grade for wear resistance in cutoff and grooving applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating improves heat resistance and extends tool life at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e4 mm cutting width with 0-degree lead angle and neutral hand for straightforward parting setups\u003c\/li\u003e\n  \u003cli\u003eCM chipbreaker geometry promotes controlled chip evacuation during cutoff passes\u003c\/li\u003e\n  \u003cli\u003e2-degree relief angle reduces rubbing and tool pressure at the cutting zone\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method for secure, repeatable seating in A2-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A2-series clamp-style cutoff and grooving toolholders that accept a 4 mm insert seat size.

Use the appropriate torque wrench or clamp screw driver as specified by the toolholder manufacturer to seat the insert without over-tightening. Inspect the insert pocket and clamp for chips or debris before seating a new insert. Follow the toolholder manufacturer guidelines for feed rate and depth-of-cut recommendations specific to the KCU25 grade.\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\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: 4 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.71 mm (0.4217 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.68 mm (0.1843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees, Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0080 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.006 pounds\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\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: 4111109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730441601330,"sku":"4111109","price":403.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b500bba9091e0bedab4ef41b0f636d4.jpg?v=1788717521","url":"https:\/\/voomisupply.com\/products\/kennametal-4111109-carbide-cutoff-insert-4mm-a2-kcu25","provider":"Voomi Supply","version":"1.0","type":"link"}
