Built on the Beyond Evolution series platform, it features a 4.00 mm (0.1575 inch) cutting width and a neutral lead angle with a 0-degree lead angle geometry, making it suitable for straight, perpendicular cutoff work. The insert carries the KCU25 manufacturer grade with an AlTiN coating applied via PVD process, which supports extended tool life under high-speed dry or near-dry cutting conditions. A CM chipbreaker geometry controls chip flow during deep cutoff passes. Licensed machinists and CNC operators working in metal fabrication and production turning environments install and index this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in cutoff and grooving toolholders compatible with the EC-U insert style and seat size 4. It is a single-end insert, meaning it provides one cutting edge per piece. Typical applications include production parting of bar stock, tube, and shaft workpieces in ferrous and non-ferrous materials. The EC040M04N00CM02 insert designation identifies the geometry, chipbreaker, and dimensional envelope. This insert is sold individually with a minimum order quantity of 10 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with KCU25 grade and PVD-applied AlTiN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e4.00 mm (0.1575 inch) cutting width for consistent parting slot dimensions\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle (0 degrees) for straight, perpendicular cutoff passes\u003c\/li\u003e\n\u003cli\u003eCM chipbreaker geometry for controlled chip evacuation during cutoff operations\u003c\/li\u003e\n\u003cli\u003eSingle-end design; one active cutting edge per insert\u003c\/li\u003e\n\u003cli\u003eBeyond Evolution series geometry for demanding production turning environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in EC-U style cutoff and grooving toolholders with an insert seat size of 4.

Power down and lock out the machine spindle before accessing the toolholder pocket. Use the correct torque wrench and insert seating procedure specified by the toolholder manufacturer to avoid micro-fractures in the carbide. Inspect the insert seat and clamping screw for wear or debris 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 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\u003eCutting Width\u003c\/strong\u003e: 4.00 mm (0.1575 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\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\u003eInsert Seat Size\u003c\/strong\u003e: 4\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\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\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 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\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5941080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748424581426,"sku":"5941080","price":305.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b49cfaf93ab470e31edf7e0ad987f46a_3e4ccd10-7530-485a-b06c-d13fe7ad7b2f.jpg?v=1788893655","url":"https:\/\/voomisupply.com\/products\/kennametal-5941080-cutoff-insert-4mm-neutral-beyond-evolution","provider":"Voomi Supply","version":"1.0","type":"link"}
