It carries a 4 mm (0.1575 inch) cutting width, a neutral lead angle of 0 degrees, and a 2-degree relief angle. The insert is finished with an AlTiN coating applied via a PVD process, which provides thermal resistance and edge hardness at elevated cutting speeds. Grade KCU25 is suited for interrupted cuts and demanding turning applications. The CF chipbreaker geometry promotes chip control in medium-duty cutoff work. Machinists and tool-and-die professionals install this insert into compatible A2-series clamping toolholders.\u003c\/p\u003e\u003cp\u003eThis insert fits A2-series cutoff and grooving toolholders using a clamp-style insert holding method. It is appropriate for use on ferrous and non-ferrous workpiece materials in both production turning and job-shop environments. The 0.008-inch corner radius and 4.68 mm (0.1843 inch) cutting height make it suited for shallow to moderate-depth parting operations on small to medium-diameter bar stock. Both manual and CNC turning applications are within its intended use range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 mm (0.1575 inch) cutting width for precise parting and grooving\u003c\/li\u003e\n\u003cli\u003eKCU25 carbide grade with AlTiN coating via PVD process for edge durability\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry for reliable chip evacuation in medium-duty cuts\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral hand for straight cutoff entry\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing on the cut face\u003c\/li\u003e\n\u003cli\u003eSingle-end insert; overall length of 0.4217 inch (10.71 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in A2-series clamping-style cutoff and grooving toolholders with an insert seat size of 4.

Power down and lock out the machine spindle before seating or removing the insert. Use the correct torque wrench or clamp screw driver specified by the toolholder manufacturer — do not overtighten the clamp, as this can chip the carbide. Inspect the insert seat for debris or wear before seating a new insert to ensure proper support and alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 040\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: 4.00 mm (0.1575 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.71 mm (0.4217 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.68 mm (0.1843 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.008 inch\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\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\u003eSeries\u003c\/strong\u003e: A2\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: 4\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\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\u003eWeight\u003c\/strong\u003e: 0.006 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: 4111108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748233412914,"sku":"4111108","price":405.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8879e82f1f986d269a21fd0f23f41dfd.jpg?v=1788890782","url":"https:\/\/voomisupply.com\/products\/kennametal-4111108-cutoff-insert-kcu25-carbide-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
