It features the EG insert style with a GUN chip breaker geometry and KCU25 grade substrate finished with an Al2O3 PVD coating. The neutral hand orientation suits standard radial grooving setups. With a 0.250-inch cutting width, a 0.118-inch maximum depth of cut, and a 0.032-inch corner radius, this insert delivers consistent dimensional control in medium to high-speed turning applications. It is installed by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving ferrous and non-ferrous workpiece materials in both roughing and semi-finishing passes within the 0.100-inch to 0.150-inch depth-of-cut range. The Beyond Evolution series is engineered for demanding turning applications where tool life and edge consistency are critical. Typical use cases include O-ring groove machining, snap-ring groove cutting, and profile grooving on shafts and bores in aerospace, automotive, and general manufacturing settings. The insert seats into compatible EG-style grooving toolholders designed for the size-6 insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide KCU25 grade with Al2O3 PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eGUN chip breaker geometry promotes controlled chip evacuation during grooving\u003c\/li\u003e\n  \u003cli\u003e0.250-inch cutting width with a 0.032-inch corner radius for precise groove profiles\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for standard radial grooving setups\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.118 inches, operating range 0.100 to 0.150 inches\u003c\/li\u003e\n  \u003cli\u003eBeyond Evolution series construction targets extended tool life in production turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with EG-style grooving toolholders that accept size-6 grooving inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the correct torx or hex key to the clamping screw specification listed in the toolholder documentation — do not overtighten, as this can fracture the carbide substrate. Verify insert seating and edge alignment before returning the machine to cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: EG\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GUN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth of Cut Range\u003c\/strong\u003e: 0.100 to 0.150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.032 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.201 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.201 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 2.25 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Beyond Evolution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.57 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\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: 6231861\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728848322866,"sku":"6231861","price":329.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/450f037370c0cc569fb52694cdb70d0a.jpg?v=1788696788","url":"https:\/\/voomisupply.com\/products\/kennametal-6231861-grooving-insert-eg6gun-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
