It belongs to the A2 series and carries the KCU25 manufacturer grade, a PVD-applied AlTiN coating that supports higher cutting speeds and extended tool life in ferrous and difficult-to-machine materials. The insert delivers a 3.00 mm (0.1180 inch) cutting width with a 15-degree right-hand lead angle, a 2-degree relief angle, and a CF chipbreaker geometry. It is held in place by a clamp-style toolholder and is sized for an insert seat size of 3.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning environments where consistent chip control and dimensional accuracy in cutoff and grooving applications are required. The CF chipbreaker geometry promotes controlled chip formation at moderate feed rates, making it appropriate for both roughing and finishing passes on steel, alloy steel, and similar materials. The right-hand lead angle configuration directs cutting forces toward the chuck, supporting stable cuts on standard right-hand parting toolholders. Machinists and CNC operators in job shops and production facilities are the primary installers of this insert type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e3.00 mm (0.1180 inch) cutting width for precise parting and grooving\u003c\/li\u003e\n\u003cli\u003e15-degree right-hand lead angle directs cutting forces toward the chuck for stability\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry promotes controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing on the workpiece wall\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eSingle-end insert  -  one cutting edge per insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for A2 series clamp-style parting and grooving toolholders accepting insert seat size 3 with a 3.00 mm cutting width.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and the spindle locked out per applicable machine safety procedures. Use the correct torque-rated clamp screw and seat per the toolholder manufacturer's specifications  -  do not over-tighten the clamping screw by feel alone. Inspect the insert pocket and clamp for wear or damage before seating a new insert. Verify lead angle direction matches the toolholder orientation before commencing a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\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: 030\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\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: 3.00 mm (0.1180 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.50 mm (0.4134 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\u003eLead Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Right Hand\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4111104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743893750066,"sku":"4111104","price":392.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfb48fe769366d780311680b0e061e8e.jpg?v=1788850987","url":"https:\/\/voomisupply.com\/products\/kennametal-4111104-carbide-cutoff-insert-3mm-kcu25-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
