It carries a KCU25 manufacturer grade with a PVD-applied AlTiN coating, which provides heat resistance and extended tool life in demanding cutting conditions. The insert is left-hand oriented, with a cutting width of 2.39 mm (0.0941 inch) and a maximum depth of cut of 3.18 mm (0.1252 inch). It uses a clamp-style holding method and is installed by qualified machinists or tooling technicians working with precision turning equipment.\u003c\/p\u003e\u003cp\u003eThis insert is suited for metric-dimensioned grooving applications in both production and job-shop environments. The NU insert style with a 90-degree included angle and a 45-degree lead angle makes it appropriate for square-shoulder grooving profiles. The 0.51 mm (0.0197 inch) corner radius produces a controlled radius at the groove base rather than a sharp corner. It is well-matched to materials within the C2 and C6 material grade ranges, covering a broad spectrum of workpiece materials encountered in general turning work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 grade with PVD AlTiN coating for thermal stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation, NU3094 insert style\u003c\/li\u003e\n\u003cli\u003eCutting width of 2.39 mm with a maximum depth of cut range of 3.00 to 4.00 mm\u003c\/li\u003e\n\u003cli\u003e90-degree included angle and 45-degree lead angle for square-shoulder grooving\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use tool designation allows use across compatible Top Notch system holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 4033883 belongs to the Top Notch series and is cross-referenced under MSC\/Manufacturer Number NU3094R\/L.

Use the appropriate torque wrench and clamp hardware specified for the Top Notch toolholder to secure the insert — do not overtighten the clamp screw by hand estimation alone. Inspect the insert pocket and clamp for chips or debris before seating the insert. Follow the machine tool manufacturer and toolholder manufacturer guidelines for insert indexing and replacement intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NU\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: 2.39 mm (0.0941 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.18 mm (0.1252 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 to 4.00 mm (0.1000 to 0.1500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 8.74 mm (0.3440 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.95 mm (0.195 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.51 mm (0.0197 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 45 degrees\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3094\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4033883\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730777112882,"sku":"4033883","price":389.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5383b2a99009c71a7e4337e0b98480db.jpg?v=1788722696","url":"https:\/\/voomisupply.com\/products\/kennametal-4033883-grooving-insert-kcu25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
