This left-hand insert carries a KC730 grade designation with a PVD-applied TiN coating, providing wear resistance and thermal stability during interrupted and continuous cuts. The cutting width measures 3.18 mm (0.1252 inches) and the maximum depth of cut is 3.81 mm (0.1500 inches). A full radius geometry with a corner radius of 1.59 mm (0.0626 inches) and a positive 10-degree rake angle help control chip flow and reduce cutting forces on the workpiece.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving applications in metalworking and machining environments where precision groove geometry and reliable tool life are required. The K chip breaker configuration manages chip evacuation effectively during medium to moderate depth passes. It is rated for C2, C3, and C4 material grades, making it appropriate for use on a range of ferrous and non-ferrous workpiece materials. The insert style is NR with an insert size designation of 3062, fitting compatible Top Notch toolholders. Installation and changeout are performed by machinists and CNC lathe operators during scheduled tooling maintenance or job changeovers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eFull radius geometry with 1.59 mm corner radius for consistent groove profile\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle reduces cutting forces and aids chip control\u003c\/li\u003e\n\u003cli\u003eK chip breaker design manages chip evacuation during grooving passes\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for dedicated left-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eCompatible with C2, C3, and C4 material grade workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NR-style grooving inserts with a 3062 insert size designation.

Power down and lock out the machine fully before changing inserts. Use the correct torque wrench or insert key specified for the Top Notch toolholder clamping mechanism — do not overtighten or use improvised tools. Inspect the toolholder pocket and clamping screw for wear or damage before seating the replacement insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3062\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\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: TiN\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.59 mm (0.0626 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0176 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: 1114220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738694418738,"sku":"1114220","price":276.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79df8d3d817d543d38fc2a3206f0524f.jpg?v=1788802955","url":"https:\/\/voomisupply.com\/products\/kennametal-1114220-grooving-insert-nr3062k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
