It carries a KCU25 grade designation with a PVD-applied AlTiN coating for improved wear resistance and thermal stability at the cutting edge. The insert delivers a 1.04 mm cutting width and a maximum depth of cut of 1.27 mm, making it well suited for shallow, tight-tolerance grooves in ferrous and non-ferrous materials. It is a left-hand orientation insert held in place by a clamp-style toolholder. Machinists and CNC turning specialists are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in grooving applications where controlled chip formation and consistent groove width are critical. The Top Notch series is a widely recognized platform in production turning environments, applicable to both light-duty and medium-duty grooving on small-diameter workpieces. The metric insert size designation is 2041, and the material grade rating is C2 and C6, covering a broad range of workpiece materials. The AlTiN coating supports dry or minimal-coolant machining strategies where heat buildup at the cutting zone must be managed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD AlTiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e1.04 mm cutting width for precise, repeatable groove dimensions\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.27 mm, suitable for shallow grooving operations\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for compatible Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e0.09 mm corner radius minimizes stress concentration at groove walls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept the NG2041 insert size.

Ensure the toolholder pocket is clean and free of chips before seating the insert. Do not exceed the rated maximum depth of cut, as overloading a grooving insert can cause sudden fracture. Verify left-hand orientation matches the toolholder before tightening the clamp.\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: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2041\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.04 mm (0.0409 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.27 mm (0.0500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 to 2.00 mm (0.0000 to 0.0750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 mm (0.0035 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 5.56 mm (0.2190 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.84 mm (0.151 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 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\u003ePackage Height\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 9.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4109665\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749670814002,"sku":"4109665","price":59.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d0d4d4c1b979f5542859bcb39c99d2b.jpg?v=1788909014","url":"https:\/\/voomisupply.com\/products\/kennametal-4109665-grooving-insert-ng2041-kcu25-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
