Manufactured to the NG3078 insert style in the Top Notch series, it carries a KC730 grade with a PVD-applied TiN coating for improved wear resistance and surface finish on the workpiece. The insert features a left-hand orientation, a 1.98 mm cutting width, and a maximum depth of cut of 2.39 mm. A neutral rake geometry and a 0.19 mm corner radius make it suitable for controlled, consistent material removal. Machinists and CNC operators install this insert when grooving ferrous and non-ferrous materials within the C2, C3, and C4 material grades.\u003c\/p\u003e\n\u003cp\u003eThis insert fits into Top Notch series toolholders configured for NG-style inserts. It is suited for external grooving and light parting operations on bar stock, shafts, and turned components in both production and job-shop environments. The left-hand orientation positions it for specific toolholder setups where the cutting force direction requires a left-hand insert. The 3078 insert size keeps it compatible with the corresponding NG3 pocket toolholders commonly found in light-to-medium turning applications. No full-radius geometry is applied, which preserves sharp groove wall definition.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability during grooving\u003c\/li\u003e\n  \u003cli\u003eKC730 grade with PVD TiN coating for extended tool life on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e1.98 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for use with compatible left-hand Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle for balanced cutting forces and consistent chip formation\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius for defined groove geometry without full-radius profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series NG3-style toolholders.

The machine spindle must be fully stopped and the turret locked out before seating or replacing the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp to the correct seating torque per the toolholder documentation. Inspect the insert pocket for chips or debris before seating to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\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: 3078\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: 1.98 mm (0.0780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 to 3.00 mm (0.0750 to 0.1000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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: 0.0257 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: 1113079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744532136242,"sku":"1113079","price":251.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24fab1bb3e80979c1b8a1a372d4a107d.jpg?v=1788857637","url":"https:\/\/voomisupply.com\/products\/kennametal-1113079-grooving-insert-ng3078-kc730-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
