It carries a multi-layer CVD coating — TiC, TiCN, and TiN — applied over a KC850 carbide grade substrate rated for ISO material grades C5 and C6. The insert delivers a 3.18 mm (0.1252 inch) cutting width and a maximum depth of cut of 3.81 mm (0.1500 inch). With a neutral rake geometry and a 0.19 mm corner radius, it is suited for stable, consistent groove profiles in steel and cast iron applications. Licensed machinists and CNC operators working in production turning environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is built to the NF3125 size standard within the Kennametal Top Notch series, a common platform used in dedicated grooving toolholders on production turning machines. It is configured for right-hand operation and carries a 55-degree included angle with a 3-degree lead angle. The Top Notch system is frequently used in high-volume turning cells where fast insert indexing and repeatable seating are required. It is appropriate for both OD grooving and light-duty parting operations where cutting width and depth tolerances are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with CVD-applied TiC, TiCN, and TiN multilayer coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eKC850 grade with C5 and C6 material classification, suited for steel and cast iron turning\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with a maximum depth of cut range of 3.00 to 4.00 mm\u003c\/li\u003e\n\u003cli\u003e0.19 mm corner radius with neutral rake for stable groove geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation, Top Notch series platform\u003c\/li\u003e\n\u003cli\u003e55-degree included angle and 3-degree lead angle for controlled chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series grooving toolholders that accept NF3125 style inserts.

Use the toolholder manufacturer's recommended torque driver or clamping screw to secure the insert — do not use impact tools on insert clamping hardware. Inspect the toolholder pocket for chips or debris before seating the insert to ensure full contact and repeatable tool length. Insert handling should be done with care; carbide edges are brittle and will chip if dropped or contacted with hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\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: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.3440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 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\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0397 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1113912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728498229554,"sku":"1113912","price":265.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb2d6c5cdc7a7610d039f700b0f2ba18.jpg?v=1788692192","url":"https:\/\/voomisupply.com\/products\/kennametal-1113912-grooving-insert-nf3125-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
