It carries the KC850 manufacturer grade with a CVD-applied multilayer coating sequence of TiC, TiCN, and TiN, providing wear resistance and thermal stability during interrupted and continuous cuts. The insert features a left-hand cutting orientation, a 4.80 mm cutting width, and a maximum depth of cut of 3.81 mm. It belongs to KENNAMETAL's Top Notch series, a widely used indexable grooving platform in production turning environments. Licensed machinists and CNC operators install this insert as a direct component of the Top Notch toolholder system.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving, parting, and profile turning applications on steel, alloy steel, and similar workpiece materials in the C5 and C6 material grade ranges. The left-hand orientation makes it appropriate for front-to-back or specific spindle-direction grooving setups. It is used in both high-production and job-shop environments where repeatable groove dimensions and surface finish are required. The neutral rake geometry and 55-degree included angle support controlled chip formation in moderate to aggressive cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with CVD multilayer TiC, TiCN, and TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e4.80 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation for specific grooving setups\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.57 mm for controlled transition geometry at groove edges\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle supports stable chip formation across a range of materials\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for direct use in matching KENNAMETAL toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series grooving toolholders that accept the NG3189 insert size.

Power down and lock out the machine spindle before seating or replacing any insert. Use the appropriate KENNAMETAL Top Notch clamping mechanism and tighten to the toolholder manufacturer's specified procedure. Inspect the insert seat for chips or debris before installation to ensure proper seating and prevent premature insert failure.\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.80 mm (0.1890 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.57 mm (0.0225 inches)\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\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3189\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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: 0.0276 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: 1113897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727174009138,"sku":"1113897","price":283.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1490fe34612b54f27bf90b4d6cc14640.jpg?v=1788674318","url":"https:\/\/voomisupply.com\/products\/kennametal-1113897-grooving-insert-ng3189-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
