Running in the Top Notch insert system, this right-hand insert carries a CVD-applied multilayer coating of TiC, TiCN, and TiN that builds hardness and oxidation resistance for extended tool life in steel and cast iron applications. The cutting width is 0.25 inches (6.35 mm) with a maximum depth of cut of 0.25 inches (6.35 mm). The full-radius geometry and a 55-degree included angle make this insert well suited to profiling and grooving where consistent chip control and surface finish are priorities. Insert material grade is KC850, rated for material grades C5 and C6.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metal-cutting environments where grooving, recessing, or cutoff operations are performed on lathes equipped with Top Notch toolholders. The NR insert style with neutral rake and full radius is a standard configuration for general-purpose external grooving on ferrous and non-ferrous workpieces. The insert seat size is 4, and the insert size designation is 4125. Typical end users are CNC machinists and toolroom technicians in production and job-shop settings working with steel, alloy steel, and similar workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiC, TiCN, and TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eCutting width of 0.25 inches (6.35 mm) with maximum depth of cut of 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003eFull-radius geometry with corner radius of 0.1252 inches (3.18 mm) for smooth profiling\u003c\/li\u003e\n  \u003cli\u003eNeutral rake, 55-degree included angle suited to general external grooving\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility for use with standard Top Notch toolholding systems\u003c\/li\u003e\n  \u003cli\u003eKC850 grade targeting C5 and C6 material groups including steel and cast iron\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.

Seat the insert firmly against all locating surfaces in the toolholder pocket before clamping to ensure accurate cutting-edge positioning. Inspect the insert seat for chips or debris before each insert change, as contamination will affect edge height and cutting performance. Follow the toolholder manufacturer's torque recommendations for the clamping screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, 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 Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.2000 to 0.3000 inches (5.00 to 10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1252 inches (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.4530 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0567 pounds\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: 1113830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753216082226,"sku":"1113830","price":377.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4638fa35dc625dc512ee5463b177ecb2.jpg?v=1788933993","url":"https:\/\/voomisupply.com\/products\/kennametal-1113830-grooving-insert-nr4125-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
