Built to the Top Notch series standard, it carries the NG2047K insert style designation and features a KCU25 grade substrate with a PVD-applied AlTiN coating for extended tool life in demanding cut conditions. The insert delivers a cutting width of 1.19 mm (0.0469 inch) and a maximum depth of cut of 1.27 mm (0.0500 inch), making it well suited for fine grooving work requiring tight dimensional control. A clamp-style insert holding method ensures secure seating during interrupted or high-feed passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalworking operations where precise groove geometry and consistent surface finish are required. The right-hand cutting orientation positions it for standard lathe setups. The KCU25 grade with AlTiN finish is appropriate for a range of workpiece materials including steels and cast irons where heat resistance and wear resistance at the cutting edge are priorities. Machinists and tooling technicians in production shops and maintenance environments are the primary installers of this style of insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, KCU25 manufacturer grade with C2 and C6 material grade equivalents\u003c\/li\u003e\n  \u003cli\u003ePVD-applied AlTiN coating for heat resistance and extended edge life\u003c\/li\u003e\n  \u003cli\u003eCutting width: 1.19 mm (0.0469 inch)\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut: 1.27 mm (0.0500 inch), with a cut range up to 2.00 mm\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.09 mm (0.0035 inch) for controlled groove geometry\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method for rigid, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation, NG insert style, Top Notch series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series grooving toolholders that accept NG2047 style inserts with clamp-style holding.

Use the appropriate torx or clamp fastener specified by the toolholder manufacturer to secure the insert — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the toolholder pocket and clamp for wear or debris before seating the new insert. Always verify insert orientation and cutting hand match the programmed tool path before resuming operations.\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\u003eInsert Size\u003c\/strong\u003e: 2047\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: 1.19 mm (0.0469 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.27 mm (0.0500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 mm to 2.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 5.56 mm (0.2190 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.84 mm (0.151 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 mm (0.0035 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: 0.004 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: 4109670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735546200370,"sku":"4109670","price":214.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a0b737813b963d993807bf811ddd6f1.jpg?v=1788772961","url":"https:\/\/voomisupply.com\/products\/kennametal-4109670-grooving-insert-kcu25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
