Manufactured in the NRD4125 style and offered in the KCU10 grade with a PVD-applied AlTiN coating, this insert delivers wear resistance and thermal stability during interrupted and continuous cuts. The left-hand orientation suits specific toolholder configurations in the Top Notch series. With a 0.2500 inch (6.35 mm) cutting width and a maximum depth of cut of 0.5000 inch (12.70 mm), it covers a wide range of grooving depths in a single insert geometry. Machinists and CNC turning specialists are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and parting applications on ferrous and non-ferrous workpieces in both job shop and production environments. It is intended for use in Top Notch series toolholders that accept the 4125 insert seat size. The clamp-style holding method provides rigid insert retention during heavy interrupted cuts. The full-radius geometry at 0.1252 inch (3.18 mm) corner radius supports smooth groove-bottom finishes. This insert is sold individually but requires a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU10 grade with PVD AlTiN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFull radius geometry with 0.1252 inch (3.18 mm) corner radius for smooth groove bottoms\u003c\/li\u003e\n  \u003cli\u003e0.2500 inch (6.35 mm) cutting width with up to 0.5000 inch (12.70 mm) maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003eLeft-hand orientation for compatible Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding for rigid, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle supports V-profile and general grooving geometries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting insert seat size 4 and the NRD4125 insert style.

Use the manufacturer-specified clamp and torque driver for the Top Notch clamping system — do not overtighten or substitute hardware. Inspect the insert seat and clamp for chips or debris before seating the insert. Confirm left-hand orientation matches the toolholder before engaging the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NRD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5000 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.3000 to 1.0000 inch (10.00 to 20.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1252 inch (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.4530 inch (11.51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.3633 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.256 inch (6.50 mm)\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\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 3.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.8 inches\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: 4176119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753693675826,"sku":"4176119","price":258.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4659a77b27f042be4fd85dd60c02a049.jpg?v=1788939602","url":"https:\/\/voomisupply.com\/products\/kennametal-4176119-grooving-insert-nrd4125-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
