It carries the KC850 manufacturer grade and features a multilayer CVD coating of TiC, TiCN, and TiN for wear resistance and extended tool life. The insert delivers a 1.98 mm cutting width with a maximum depth of cut of 2.39 mm. A positive rake angle of 10 degrees and a K-style chip breaker promote efficient chip evacuation in a variety of workpiece materials. This insert is installed by machinists and toolroom technicians working with carbide toolholders in the Top Notch series.\u003c\/p\u003e\u003cp\u003eThe 1114901 is suited for grooving applications in medium to finish turning operations where dimensional accuracy and surface finish are critical. The right-hand orientation and insert size designation of 3078 make it compatible with Top Notch series toolholders configured for that profile. A 55-degree included angle and a 0.19 mm corner radius support controlled material removal in tight groove geometries. Material grades C5 and C6 indicate suitability for machining steel, cast iron, and similar ferrous materials at moderate to higher cutting speeds. It is sold in multiples of 5 units per order with 1 insert per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade solid carbide with multilayer CVD TiC, TiCN, and TiN coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e1.98 mm cutting width with a maximum depth of cut of 2.39 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 10 degrees with K-style chip breaker for reliable chip control\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation, insert size 3078, Top Notch series\u003c\/li\u003e\n\u003cli\u003e0.19 mm corner radius and 55-degree included angle for precise groove geometry\u003c\/li\u003e\n\u003cli\u003eMaterial grades C5 and C6 suitable for steel and cast iron applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders accepting the NG3078 insert profile.

Ensure the machine spindle is fully stopped and all energy is locked out before seating or replacing inserts. Verify insert orientation matches the toolholder pocket designation before securing the clamping screw. Inspect the pocket for debris or damage that could affect seating and cutting accuracy.\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\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\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\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3078\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0205 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package, minimum order quantity of 5\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: 1114901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734708355378,"sku":"1114901","price":284.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a05a54ee15d95cbad44a73fc2a4cde92.jpg?v=1788765531","url":"https:\/\/voomisupply.com\/products\/kennametal-1114901-grooving-insert-kc850-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
