Built to the NR insert style in the Top Notch series, it carries a KC850 grade substrate with a multilayer CVD coating of TiC, TiCN, and TiN for wear resistance and extended tool life in steel and cast iron applications. The insert features a 3.96 mm cutting width, a maximum depth of cut of 3.81 mm, and a full corner radius of 1.98 mm. Right-hand orientation and a neutral rake geometry make it a straightforward drop-in for compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium to finishing passes in grooving applications across general-purpose turning on ferrous materials. The KC850 grade with CVD coating performs well in continuous and mildly interrupted cuts on steel workpieces classified under material grades C5 and C6. It is sized to the 3078 insert size standard and is intended for use by machinists and CNC operators in job shop and production turning environments. Minimum order quantity is 5 inserts; each package contains 1 insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate, KC850 grade with multilayer CVD coating: TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e3.96 mm cutting width with a full corner radius of 1.98 mm\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 3.81 mm; depth of cut range: 3.00 mm to 4.00 mm\u003c\/li\u003e\n\u003cli\u003eRight-hand, neutral rake geometry for consistent chip control\u003c\/li\u003e\n\u003cli\u003eNR insert style, Top Notch series for compatibility with standard Top Notch toolholding systems\u003c\/li\u003e\n\u003cli\u003e55-degree included angle for grooving profile geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NR-style inserts, insert size 3078.

Ensure the machine spindle is fully stopped and locked out before seating or removing inserts. Use the correct Top Notch clamping screw and torx key for the toolholder to secure the insert without over-tightening. Confirm insert orientation and hand designation match the toolholder before initiating a cut.\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: 3078\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\u003eCutting Width\u003c\/strong\u003e: 3.96 mm (0.1559 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\u003eDepth 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: 1.98 mm (0.0780 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\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eWeight\u003c\/strong\u003e: 0.0223 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: 1113827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748360880434,"sku":"1113827","price":270.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed0d75fe88e9f41ba860b2d7c71ee1eb.jpg?v=1788892910","url":"https:\/\/voomisupply.com\/products\/kennametal-1113827-nr3078-kc850-grooving-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
