Built to the NG style Top Notch series, this right-hand insert carries a KC850 grade with a CVD-applied TiC, TiCN, and TiN multilayer coating for thermal resistance and edge wear protection. The cutting width measures 1.98 mm (0.0780 inches) with a maximum depth of cut of 2.39 mm (0.0941 inches). A 0.19 mm (0.0075 inch) corner radius and a neutral rake geometry suit finishing and light roughing passes in ferrous and non-ferrous materials. Machinists and toolroom technicians install this insert in compatible Top Notch grooving toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving applications on production turning equipment in both job shop and high-volume manufacturing environments. The KC850 carbide grade with CVD multilayer coating targets steel, cast iron, and similar workpiece materials in the C5 and C6 material grade ranges. The Top Notch series is a common platform in turning departments where quick insert indexing and repeatable seating are priorities. The included angle of 55 degrees and a lead angle of 3 degrees define the insert geometry for narrow-groove profiling work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade solid carbide with CVD-applied TiC, TiCN, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e1.98 mm (0.0780 inch) cutting width for precise narrow-groove work\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 2.39 mm (0.0941 inch) within a range of 2.00 to 3.00 mm\u003c\/li\u003e\n\u003cli\u003e0.19 mm corner radius and neutral rake for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation; single-use insert (not a multi-use tool)\u003c\/li\u003e\n\u003cli\u003eTop Notch series for fast, repeatable indexing in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series grooving toolholders.

Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification using the correct Torx or hex key. Inspect the insert seat for chips or debris before seating to ensure proper support and avoid premature insert fracture. Do not exceed the rated maximum depth of cut for the insert size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right 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\u003eInsert Height\u003c\/strong\u003e: 0.3440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\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: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3078\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: 0.0201 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: 1113885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732027932978,"sku":"1113885","price":283.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2763a04601ef0d264219dac5b9c4b741.jpg?v=1788738334","url":"https:\/\/voomisupply.com\/products\/kennametal-1113885-ng3078-kc850-grooving-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
