Manufactured to the EC-U insert style and sold under the Beyond Evolution series, this single-end insert features a 3.00 mm cutting width, a neutral lead angle, and a 2-degree relief angle. The AlTiN coating applied via PVD process improves heat resistance and tool life during high-speed cutoff work. The CR chipbreaker geometry promotes controlled chip evacuation, reducing the risk of chip packing in deep grooving or cutoff applications. Machinists and toolroom technicians working in production or job-shop environments will find this insert suited to steel, cast iron, and similar workpiece materials corresponding to material grades C2 and C6.\u003c\/p\u003e\u003cp\u003eThis insert is intended for cutoff and grooving toolholders that accept the EC-U insert style with a seat size of 3. It is appropriate for use in residential machine shops, production turning departments, and aerospace or general metalworking environments where consistent parting performance and close dimensional tolerances are required. The neutral hand orientation allows use in standard straight cutoff applications without directional bias.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 mm cutting width with neutral lead angle and neutral hand for standard cutoff setups\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process for improved heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eCR chipbreaker geometry promotes positive chip control and evacuation\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing on the cut face\u003c\/li\u003e\n\u003cli\u003eSingle-end insert design; EC-U insert style, insert seat size 3\u003c\/li\u003e\n\u003cli\u003eMaterial grades C2 and C6 cover a broad range of ferrous and non-ferrous workpiece applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with EC-U style cutoff and grooving toolholders that accept insert seat size 3.

Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer when securing the insert. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert. Never exceed the cutting parameters recommended by KENNAMETAL for the KCU25 grade and the workpiece material in use.\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\u003eSeries\u003c\/strong\u003e: Beyond Evolution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eCutting Width\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.1020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.60 mm (0.3780 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.00 mm (0.1181 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: CR\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: 3\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 0.59 inches (W) x 0.59 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: 5941081\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753180397874,"sku":"5941081","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1747f87b68cb176382af737737a05f1_9931d47e-39a1-46c5-be56-6ba1056035a5.jpg?v=1788933576","url":"https:\/\/voomisupply.com\/products\/kennametal-5941081-cutoff-insert-kcu25-carbide-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
