Manufactured under the Beyond Evolution series, this single-end insert carries a KCU25 grade with an AlTiN coating applied via PVD process, delivering wear resistance and thermal stability during interrupted or continuous cut-off work. The cutting width measures 4.00 mm (0.1575 inches) with a neutral lead angle and a 2-degree relief angle. A CF chipbreaker geometry controls chip flow and reduces cutting forces in steel and similar workpiece materials. Licensed machinists and CNC operators install this insert as a direct replacement in compatible EC-U style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert fits residential-scale job shops and high-production industrial turning operations alike. It is suited for cut-off applications on steel and mid-range alloys where a 4 mm parting width is required. The neutral hand designation means it works in standard right-hand and left-hand configurations depending on toolholder setup. The Beyond Evolution series targets demanding turning environments where consistent edge life and predictable chip control are priorities. Installation requires a compatible EC-U insert seat sized for a seat size 4 designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with AlTiN PVD coating for extended tool life in steel cutting\u003c\/li\u003e\n\u003cli\u003e4.00 mm (0.1575 inch) cutting width with CF chipbreaker geometry\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral hand — no directional restriction at the toolholder\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing on the part face during parting\u003c\/li\u003e\n\u003cli\u003eSingle-end design with EC-U insert style for secure seating in compatible holders\u003c\/li\u003e\n\u003cli\u003eBeyond Evolution series construction targeting high-demand CNC turning applications\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 designation, as specified by the manufacturer for the Beyond Evolution series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutoff inserts are installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing any insert. Use the correct torque wrench and insert clamp screw per the toolholder manufacturer's specification — do not overtighten by hand. Inspect the insert seat for chips or debris before seating the new insert to ensure full, even contact.\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 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\u003eCutting 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\u003eOverall Length\u003c\/strong\u003e: 10.19 mm (0.4010 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\u003eCorner Radius\u003c\/strong\u003e: 0.0080 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\u003eChipbreaker\u003c\/strong\u003e: CF\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\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\u003eCutting Tool Application\u003c\/strong\u003e: Cut-off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 inches (L) x 0.67 inches (W) x 0.67 inches (H)\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: 5941076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730940854578,"sku":"5941076","price":302.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94143d7bae1e577ac1fbd57a418419b6.jpg?v=1788725088","url":"https:\/\/voomisupply.com\/products\/kennametal-5941076-cutoff-insert-kcu25-carbide-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
