Manufactured to the NG3094 insert style with a KCU25 grade, it carries a PVD-applied AlTiN coating that improves heat resistance and wear life at the cutting edge. The insert has a 0.0941-inch cutting width and a maximum depth of cut of 0.15 inches, making it well suited to narrow groove profiles. It is configured for left-hand cutting and features a double-end design with a neutral rake angle. Machinists and CNC operators in production and job-shop environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in ferrous and non-ferrous metal turning applications where consistent groove geometry and surface finish are required. The Top Notch series tooling system is a common platform for grooving and threading on general-purpose turning equipment. The double-end configuration extends insert life by providing two usable cutting edges. The 0.0075-inch corner radius delivers a controlled blend at groove edges, and the 55-degree included angle supports stable chip formation in moderate to interrupted cut conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KCU25 grade for toughness in grooving applications\u003c\/li\u003e\n  \u003cli\u003ePVD AlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.0941-inch cutting width with a maximum depth of cut of 0.15 inches\u003c\/li\u003e\n  \u003cli\u003eLeft-hand, double-end configuration for two usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e0.0075-inch corner radius for controlled groove-edge geometry\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle and 0-degree lead angle for predictable chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series grooving toolholders that accept NG-style insert seat size 3 inserts.

Seat the insert fully into the toolholder pocket and confirm the clamping screw is tightened to the toolholder manufacturer specification before resuming cutting. Inspect the insert seat for chips or debris prior to seating a new edge. Follow shop safety protocols and applicable OSHA machine-guarding requirements when servicing turning tools.\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\u003eInsert Size\u003c\/strong\u003e: 3094\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\u003eCutting Width\u003c\/strong\u003e: 0.0941 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.15 inches to 0.20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.3440 inches (8.74 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 4109790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730009850162,"sku":"4109790","price":253.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f29a92314f91d6b2bfbe6786a0124c2.jpg?v=1788710120","url":"https:\/\/voomisupply.com\/products\/kennametal-4109790-grooving-insert-ng3094-kcu25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
