It carries the NGD3094K geometry with a KC850 grade substrate and a CVD-applied multilayer coating of TiC, TiCN, and TiN. The insert is left-hand oriented with a 2.39 mm cutting width and a maximum depth of cut of 6.35 mm. The positive rake angle of 10 degrees and the K chip breaker geometry support controlled chip flow in medium to finishing grooving passes. This insert is installed and changed by CNC machinists and toolroom professionals working on turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal grooving on turned components where dimensional accuracy and surface finish are critical. The KC850 grade, with its CVD multilayer coating, is optimized for steel and alloy steel workpieces in the C5 and C6 material grade ranges. The Top Notch series toolholder system provides repeatable seating for consistent cut depth and width. The included angle of 55 degrees and a corner radius of 0.19 mm make it appropriate for grooving profiles that require a near-full-radius or defined-corner groove geometry without a full-radius tip.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiC, TiCN, and TiN for wear resistance and thermal stability\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\u003eLeft-hand insert orientation for correct engagement in NGD-style Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle with K chip breaker for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm and 55-degree included angle for defined groove geometry\u003c\/li\u003e\n\u003cli\u003eKC850 carbide grade rated for C5 and C6 material classifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series NGD-style toolholders that accept the 3094 insert size.

Seat the insert firmly into the Top Notch toolholder pocket and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert seat and clamping surfaces for chips or debris before seating to ensure proper support and avoid insert fracture. Do not exceed the rated maximum depth of cut of 6.35 mm during operation.\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\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: 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\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: 3094\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0223 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: 1114924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750914621746,"sku":"1114924","price":235.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c5811f36531b51c1fc533175ec07cd0.jpg?v=1788920588","url":"https:\/\/voomisupply.com\/products\/kennametal-1114924-grooving-insert-kc850-carbide-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
