It carries the KC850 manufacturer grade and features a CVD-applied multilayer coating of TiC, TiCN, and TiN, which provides wear resistance and thermal protection during interrupted and continuous cuts. The insert has a 2.39 mm (0.0941 inch) cutting width and a maximum depth of cut of 6.35 mm (0.2500 inch). A positive rake angle of 10 degrees and a K-style chip breaker promote controlled chip flow, reducing the risk of chip packing in deep groove applications. Installed by machinists and CNC tooling technicians.\u003c\/p\u003e\u003cp\u003eThis insert fits the Top Notch series toolholding system and is suited for grooving operations in steel and alloy materials corresponding to material grades C5 and C6. The right-hand cutting orientation makes it appropriate for standard lathe setups where the spindle rotates counterclockwise when viewed from the tailstock. The included angle of 55 degrees and a corner radius of 0.19 mm (0.0075 inch) suit finish-grooving passes where profile accuracy matters. Typical applications include OD grooving, snap-ring groove cutting, and undercut work on steel workpieces in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade solid carbide with CVD multilayer TiC, TiCN, and TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e2.39 mm cutting width with a maximum depth of cut of 6.35 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (10 degrees) with K chip breaker for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm for controlled profile accuracy at groove edges\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard OD grooving setups\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for secure, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series grooving toolholders.

Power down and lock out the machine spindle before seating or indexing the insert in its pocket. Confirm the insert is fully seated and the clamping screw is snugged to the toolholder manufacturer specification before resuming cuts. Do not exceed the rated maximum depth of cut of 6.35 mm, as overloading the insert beyond its designed range risks edge fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NGD\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: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.2000 to 0.3000 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 Angle\u003c\/strong\u003e: 10 degrees (Positive)\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3094\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\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: 1114907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728738976050,"sku":"1114907","price":202.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2d89c6f6b0b5cb6603ee87c19febfe5.jpg?v=1788695661","url":"https:\/\/voomisupply.com\/products\/kennametal-1114907-grooving-insert-kc850-carbide-top-notch","provider":"Voomi Supply","version":"1.0","type":"link"}
