It carries a KC730 grade designation with a PVD-applied TiN coating, which provides wear resistance and edge toughness on a range of workpiece materials. The insert features a left-hand cutting orientation, a 2.39 mm cutting width, and a maximum depth of cut of 2.79 mm with a full corner radius of 1.19 mm. A neutral rake geometry and 55-degree included angle round out the cutting profile. This insert is installed by machinists and CNC turning technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving, undercutting, and parting operations on metallic workpieces. The KC730 carbide grade with TiN coating is appropriate for material grades C2, C3, and C4, covering a range of cast irons, non-ferrous alloys, and general-purpose steels. The Top Notch series toolholding system provides a secure, repeatable seat, making this insert practical for both high-volume production runs and precision single-piece work where consistent groove geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiN coating for wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eKC730 manufacturer grade suited for C2, C3, and C4 material classifications\u003c\/li\u003e\n\u003cli\u003e2.39 mm cutting width with a maximum depth of cut of 2.79 mm\u003c\/li\u003e\n\u003cli\u003eFull corner radius of 1.19 mm for smooth groove floor geometry\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation with neutral rake and 55-degree included angle\u003c\/li\u003e\n\u003cli\u003eCompatible with the Top Notch series toolholding system for secure insert retention\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 inserts at size 2047.

Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the insert clamp — do not overtighten. Verify insert orientation matches the programmed tool path direction before resuming cuts. Inspect the insert seat and clamping surfaces for chips or debris before installing a new 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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2047\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\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: 2.79 mm (0.1098 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\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\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: 0.022 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: 1112974\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731108233522,"sku":"1112974","price":241.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0f486c0388e670b14950656ffb58f62.jpg?v=1788727060","url":"https:\/\/voomisupply.com\/products\/kennametal-1112974-grooving-insert-nr2047-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
