Built to the Top Notch series standard, this right-hand insert carries the KC850 manufacturer grade and features a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and thermal stability. The cutting width is 0.2500 inches (6.35 mm) and the maximum depth of cut is 0.5000 inches (12.70 mm). A positive rake angle of 10 degrees and a K-style chip breaker support controlled chip evacuation in medium to finishing-range cuts. Corner radius measures 0.0225 inches (0.57 mm). Licensed machinists and CNC operators working with steel, cast iron, and similar C5-C6 material grades are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external grooving applications where repeatable dimensional accuracy and surface finish are required. The Top Notch series is a common platform on production turning equipment used in automotive, aerospace, and general metalworking environments. With an insert seat size of 4 and an included angle of 55 degrees, it fits standard Top Notch-compatible toolholders. The maximum depth of cut range runs from 0.3000 to 1.0000 inches (10.00 to 20.00 mm), covering a broad range of groove profiles in medium-volume production or job-shop settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiC, TiCN, and TiN for extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e0.2500-inch (6.35 mm) cutting width for precise groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker promotes chip control in finishing and medium cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation; insert seat size 4, Top Notch series compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series-compatible toolholders with an insert seat size of 4.

Seat the insert fully into the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification before resuming operation. Inspect the insert seat and clamping mechanism for chips or debris before seating a new insert. Do not exceed the rated maximum depth of cut for this insert grade and geometry.\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.3000 to 1.0000 inches (10.00 to 20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0225 inches (0.57 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.4530 inches\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\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\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4250\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0606 pounds\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: 1114926\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739961065778,"sku":"1114926","price":534.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6fa46b20c09dde30995204fad626666.jpg?v=1788820774","url":"https:\/\/voomisupply.com\/products\/kennametal-1114926-grooving-insert-kc850-carbide-top-notch","provider":"Voomi Supply","version":"1.0","type":"link"}
