It carries the manufacturer grade designation KCU25 and is part of the Beyond Evolution series, finished with a PVD-applied AlTiN coating for extended tool life in demanding cutting conditions. The insert features a 1.40 mm (0.0550 inch) cutting width, a neutral lead angle, and a 2-degree relief angle. A CF chipbreaker geometry promotes controlled chip formation during cutoff work. This insert is installed by machinists and CNC operators running production turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for cutoff and parting operations in both production and job-shop turning environments. The EC-U insert style and 1B seat size position it for light to medium-duty cutoff work on bar stock and turned components. The single-end configuration means the insert is replaced rather than flipped, maintaining consistent geometry at the cutting edge. Applications include grooving and parting on ferrous and non-ferrous workpieces where tight dimensional control at the cutoff zone is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with PVD-applied AlTiN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e1.40 mm (0.0550 inch) cutting width for precision parting operations\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and 2-degree relief angle for stable cutoff entry\u003c\/li\u003e\n\u003cli\u003eBeyond Evolution series — EC-U insert style, 1B seat size\u003c\/li\u003e\n\u003cli\u003eSingle-end insert for consistent edge geometry throughout service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting EC-U style inserts with a 1B insert seat size.

Power down and lock out the machine spindle before seating or removing the insert. Use the manufacturer-specified torque wrench and clamping hardware for the toolholder to secure the insert without cracking the carbide substrate. Inspect the insert seat for chips or debris before installation to ensure full seating and accurate edge positioning.\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\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\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: 1.40 mm (0.0550 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 Length\u003c\/strong\u003e: 9.00 mm (0.3550 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.40 mm (0.0550 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: 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 Seat Size\u003c\/strong\u003e: 1B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5533081\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732573192498,"sku":"5533081","price":236.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94143d7bae1e577ac1fbd57a418419b6_d0292d93-542f-4e9d-8388-eaaafcf19fcf.jpg?v=1788744567","url":"https:\/\/voomisupply.com\/products\/kennametal-5533081-cutoff-insert-kcu25-carbide-1-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
