Built to the NRD3062K insert style in the Top Notch series, it features a KC730 grade substrate with a PVD-applied TiN coating for wear resistance and extended tool life. The insert delivers a cutting width of 3.18 mm (0.1252 inch) and a maximum depth of cut of 6.35 mm (0.2500 inch). A full-radius corner geometry with a 1.59 mm (0.0626 inch) corner radius and a K chip breaker profile support controlled chip evacuation. This insert is installed by machinists and CNC operators in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving, plunge cutting, and profiling applications on ferrous and non-ferrous workpieces classified under material grades C2, C3, and C4. The left-hand orientation dictates toolholder selection and cutting direction, making it appropriate for specific setups on gang-tool lathes, turret lathes, and Swiss-style turning machines. The neutral rake geometry and 55-degree included angle support stable cutting forces during grooving cycles. It is sold individually but carries a minimum order quantity of 5 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eKC730 manufacturer grade suited for C2, C3, and C4 material classifications\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with a full-radius corner at 1.59 mm corner radius\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 6.35 mm within a rated range of 5.00 mm to 10.00 mm\u003c\/li\u003e\n\u003cli\u003eK chip breaker design for controlled chip formation during grooving\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for compatible Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept the NRD insert style in size 3062.

Use the correct torque wrench and seating tool specified for Top Notch series clamping hardware — do not over-tighten or seat by impact. Inspect the insert pocket for debris or damage before installing a new insert. Confirm left-hand orientation alignment with the toolholder before initiating any cutting cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NRD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.18 mm (0.1252 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.59 mm (0.0626 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.2000 to 0.3000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Compatibility\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0247 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: 1114389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728631431474,"sku":"1114389","price":162.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4c5c95feb850d21fc3348322428b0c6.jpg?v=1788694202","url":"https:\/\/voomisupply.com\/products\/kennametal-1114389-grooving-insert-nrd3062k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
