It features an EC-U insert style with a 1.4 mm (0.0551 inch) cutting width and a neutral lead angle, making it suitable for straight plunge parting with consistent chip control. The CM chipbreaker geometry promotes efficient chip evacuation during cut-off passes. An AlTiN PVD coating applied over a KCU25 grade carbide substrate delivers elevated wear resistance and thermal stability in demanding turning applications. Machinists and CNC operators working in production turning environments install this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for cut-off and grooving operations in high-volume production turning, particularly where tight width tolerances and controlled chip formation are required. The Beyond Evolution series is engineered for demanding metal-cutting environments including steel and cast iron workpieces where consistent tool life is a priority. It fits insert seat size 1B toolholders designed for EC-U style cutoff inserts. The single-end configuration means the insert is replaced rather than indexed to a second cutting edge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEC-U insert style with 1B seat size for compatibility with standard cutoff toolholders\u003c\/li\u003e\n  \u003cli\u003e1.4 mm (0.0551 inch) cutting width for precision parting cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral lead angle and 2-degree relief angle for straight plunge parting\u003c\/li\u003e\n  \u003cli\u003eCM chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating applied via PVD process for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eKCU25 carbide grade, material grade C2 and C6, suited for a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end insert from the Beyond Evolution series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement cutoff insert for EC-U style, 1B seat size toolholders used in CNC turning and parting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can fracture the carbide insert. Inspect the insert pocket and seating surface for debris or damage before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1B\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: 1.40 mm (0.0551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.40 mm (0.0551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.00 mm (0.3550 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: 0.0060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CM\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\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\u003eCutting Tool Application\u003c\/strong\u003e: Cut-off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Beyond Evolution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.72 inches L x 1.89 inches W x 0.79 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\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: 5533089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727572107570,"sku":"5533089","price":273.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b49cfaf93ab470e31edf7e0ad987f46a.jpg?v=1788679530","url":"https:\/\/voomisupply.com\/products\/kennametal-5533089-cutoff-insert-kcu25-carbide-1-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
