Manufactured under the Beyond Evolution series, it carries the grade designation KCU25 with an AlTiN coating applied via PVD process, providing wear resistance and thermal stability at elevated cutting speeds. The insert features a 4 mm cutting width, a neutral lead angle, and a 2-degree relief angle with a CR chipbreaker geometry. It is intended for machinists, tool-and-die shops, and production turning operations requiring consistent cutoff performance in steel, cast iron, and similar workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light to medium-duty cutoff and grooving applications in both production and job-shop environments. The EC-U insert style and size code 4 designation correspond to compatible toolholders designed for that seat geometry. The neutral hand orientation and CR chipbreaker make it appropriate for straight cutoff passes where chip control and surface finish at the parting face are priorities. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with AlTiN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e4 mm cutting width (0.1575 inches) for standard parting applications\u003c\/li\u003e\n\u003cli\u003eCR chipbreaker geometry for controlled chip formation during cutoff\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral hand for straightforward radial cutoff passes\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing and flank wear\u003c\/li\u003e\n\u003cli\u003eSingle-end insert maximizing edge geometry precision\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cutoff insert for EC-U style toolholders with an insert seat size 4, consistent with the Beyond Evolution series toolholder system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutoff inserts of this type are installed and replaced by machinists or tooling technicians on CNC or manual turning equipment. Always index or replace inserts with the machine powered down and the spindle fully stopped. Use the appropriate torque wrench and insert-seating tool specified by the toolholder manufacturer to avoid seat damage. Inspect the insert pocket and clamping screw condition before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: EC-U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4\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\u003eSeries\u003c\/strong\u003e: Beyond Evolution\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: 10.20 mm (0.4020 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.1410 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\u003eCorner Radius\u003c\/strong\u003e: 0.0080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CR\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\u003eCutting Tool Application\u003c\/strong\u003e: Cut-off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 x 0.67 x 0.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5941082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734039691570,"sku":"5941082","price":304.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1747f87b68cb176382af737737a05f1_7aa384ae-229f-48f5-84ee-2dc001a18e39.jpg?v=1788760610","url":"https:\/\/voomisupply.com\/products\/kennametal-5941082-cutoff-insert-kcu25-carbide-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
