Manufactured under the Beyond Evolution series, it carries the KCU25 grade with a CVD-applied TiOCN coating that provides wear resistance and thermal stability during interrupted or continuous cuts. The insert features a 2 mm cutting width, a 6-degree lead angle with neutral hand orientation, and a right-hand configuration. A 2-degree relief angle reduces rubbing on the workpiece, while the CF chipbreaker geometry promotes controlled chip evacuation in medium-duty cutoff applications. Machinists and CNC operators working in production environments are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for cutoff and grooving operations on ferrous and non-ferrous workpiece materials in residential shop, job shop, and production turning environments. It is a single-end insert with an EC-U style interface and an insert seat size of 2, making it compatible with toolholders designed around that seat specification. The Beyond Evolution series targets applications where consistent tool life and chip control are priorities. No multi-use capability is specified for this insert; it is dedicated to cut-off operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 carbide grade with CVD TiOCN coating for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003e2 mm cutting width with a 6-degree neutral lead angle for controlled parting cuts\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry for reliable chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle to minimize workpiece rubbing during deep cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand, single-end insert configuration in the Beyond Evolution series\u003c\/li\u003e\n\u003cli\u003eEC-U insert style with insert seat size 2 for repeatable toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement cutoff insert for use with EC-U style toolholders accepting an insert seat size of 2, as specified by the Beyond Evolution series toolholder system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before seating or removing any insert. Use appropriate torx or hex keys to the toolholder manufacturer torque specification when securing the insert clamp. Inspect the insert pocket and clamping surfaces for debris or damage before seating a new insert to ensure accurate positioning and safe operation.\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: 2 mm (0.0788 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.0630 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2 mm (0.0788 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.97 mm (0.3530 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 6 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2 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\u003eChipbreaker\u003c\/strong\u003e: CF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiOCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\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 x 0.67 x 0.67 inches\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: 5533151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748284039474,"sku":"5533151","price":248.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41e2e451240a4e6a14b2d0e3e6808c92_90961724-82df-4741-945e-a4d31591a361.jpg?v=1788891732","url":"https:\/\/voomisupply.com\/products\/kennametal-5533151-cutoff-insert-2mm-carbide-kcu25","provider":"Voomi Supply","version":"1.0","type":"link"}
