Carrying the KC730 manufacturer grade with a PVD-applied TiN finish, this left-hand insert delivers a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 3.81 mm (0.150 inches). The full-radius geometry with a 1.19 mm corner radius and a positive rake angle of 10 degrees promotes clean chip formation and reduced cutting forces. It is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert belongs to the KENNAMETAL Top Notch series and is suited for grooving operations on materials corresponding to C2, C3, and C4 material grades, which generally include cast irons, non-ferrous materials, and non-metallic materials. The K chip breaker geometry and 55-degree included angle make it appropriate for moderate-depth grooving passes in both roughing and finishing contexts on metalworking turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD TiN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eCutting width of 2.39 mm (0.0941 inches) for precise groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 3.81 mm (0.150 inches)\u003c\/li\u003e\n\u003cli\u003eFull radius corner geometry with 1.19 mm corner radius\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle with K chip breaker for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for specific toolholder configurations\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series for indexed compatibility with matching toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series toolholders that accept NR-style, size 3047 left-hand grooving inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the correct torque driver or clamp screw tool specified for the Top Notch toolholder to seat the insert securely without over-tightening. Verify insert hand orientation matches the toolholder before beginning any cut.\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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3047\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: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.150 to 0.200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 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\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0198 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: 1114218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735227498802,"sku":"1114218","price":276.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4211afa7acf053c2d7c8db70b97b8044.jpg?v=1788770582","url":"https:\/\/voomisupply.com\/products\/kennametal-1114218-grooving-insert-nr3047k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
