Manufactured to the NG3122 style in the Top Notch series, this right-hand insert carries a KCU25 grade designation and an AlTiN coating applied via PVD process. The cutting width measures 3.10 mm (0.122 inches), with a maximum depth of cut of 3.81 mm (0.150 inches). The AlTiN finish provides thermal resistance and wear protection in demanding interrupted-cut and dry-machining applications. Machinists and toolroom technicians select this insert for consistent, repeatable groove geometry in steel and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use on production turning equipment in both job-shop and high-volume manufacturing environments. It fits clamp-style Top Notch toolholders and is appropriate for grooving operations where tight width tolerance and controlled depth are required. The metric sizing and 55-degree included angle make it well matched to metric-dimensioned groove profiles. Material grade ratings of C2 and C6 indicate suitability across a range of ferrous and non-ferrous turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with KCU25 manufacturer grade for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating via PVD process for elevated-temperature and dry-cutting performance\u003c\/li\u003e\n  \u003cli\u003e3.10 mm cutting width with a maximum depth of cut range of 3.00 to 4.00 mm\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.19 mm (0.0075 inches) for controlled groove edge geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard clamp-style Top Notch toolholder systems\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle compatible with metric groove profile requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with clamp-style Top Notch series toolholders accepting NG-style grooving inserts.

Power down and lock out the machine spindle before seating or replacing the insert. Secure the insert fully in the clamp before resuming cuts, and verify cutting width and depth-of-cut settings against the workpiece drawing before engaging the tool. Do not exceed the stated maximum depth of cut of 3.81 mm in a single pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\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: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 3.10 mm (0.122 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 to 4.00 mm (0.150 to 0.200 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 8.74 mm (0.344 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.98 mm (0.196 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\u003eInsert Size\u003c\/strong\u003e: 3122\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4109811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731027067186,"sku":"4109811","price":251.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94e12d25b62f2862cc8d0749a6e728f9.jpg?v=1788726060","url":"https:\/\/voomisupply.com\/products\/kennametal-4109811-grooving-insert-ng3122-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
