It carries a KCU25 manufacturer grade with a PVD-applied AlTiN coating, delivering strong wear resistance and thermal stability in a broad range of workpiece materials. The left-hand cutting geometry provides a 1.19 mm cutting width and a maximum depth of cut of 1.91 mm, making it well suited to narrow-groove and parting applications where precise dimensional control is required. Licensed machinists and CNC operators install and index this insert as part of a clamp-style Top Notch toolholder system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metal-cutting operations on production turning equipment. The NG-style insert geometry and 55-degree included angle are matched to Top Notch compatible toolholders. It is applicable to both roughing and finishing grooves in the 0.00 to 2.00 mm maximum depth-of-cut range, serving job shops, production floors, and maintenance machining environments. The metric sizing and insert size designation 3047 align with standard Top Notch system toolholder pockets. Minimum order quantity is 5 pieces; each package contains 1 insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD AlTiN coating for elevated wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eKCU25 grade — suitable for a wide range of ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1.19 mm cutting width with a maximum depth of cut of 1.91 mm for narrow grooving applications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting orientation with NG insert style for use in Top Notch clamp-type holders\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius provides a controlled edge break at groove shoulders\u003c\/li\u003e\n  \u003cli\u003ePVD coating process preserves sharp edge geometry while extending insert life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for Top Notch series clamp-style toolholders that accept NG3047 left-hand inserts.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before indexing or replacing the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamp, as this can chip the carbide substrate. Inspect the toolholder pocket seating surface for wear or debris before seating the new insert.\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\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: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.91 mm (0.0752 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 to 2.00 mm\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\u003eCutting Height\u003c\/strong\u003e: 8.74 mm (0.3440 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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3047\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: 0.04 pounds\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\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: 4109766\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728681271602,"sku":"4109766","price":219.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd4af92a961b172e9c7ad44151c881d6.jpg?v=1788694903","url":"https:\/\/voomisupply.com\/products\/kennametal-4109766-grooving-insert-ng3047-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
