Built from uncoated K68 carbide grade (material grade C3), this right-hand insert delivers consistent performance in non-ferrous and cast iron applications where a bright, uncoated surface is preferred. The insert features a 0.25 inch (6.35 mm) cutting width, a maximum depth of cut of 0.25 inch (6.35 mm), and a full-radius corner profile with a 0.125 inch (3.18 mm) corner radius. Neutral rake geometry supports stable chip formation across a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for precision grooving, parting, and profile turning in both production and job-shop environments. The NR4125 insert style fits standard Top Notch toolholders with an insert seat size of 4. It is appropriate for use on CNC turning centers handling non-ferrous metals, aluminum alloys, and cast iron where an uncoated carbide grade is specified. The 55-degree included angle and neutral rake make it a practical choice for controlled-depth grooving where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K68 grade (C3 material grade)  -  uncoated, bright finish for non-ferrous and cast iron cutting\u003c\/li\u003e\n\u003cli\u003e0.25 inch (6.35 mm) cutting width with full-radius corner profile\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 0.25 inch (6.35 mm); effective range 0.20 to 0.30 inch (5.00 to 10.00 mm)\u003c\/li\u003e\n\u003cli\u003eCorner radius: 0.125 inch (3.18 mm); neutral rake geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation; insert style NR, insert size 4125, seat size 4\u003c\/li\u003e\n\u003cli\u003eTop Notch series  -  indexes into compatible Top Notch grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series grooving toolholders accepting insert seat size 4 and NR-style inserts.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and clamping hardware specified for the Top Notch toolholder to secure the insert  -  do not overtighten by hand. Inspect the insert seat and clamping components for wear or debris before indexing to a new cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.25 inch (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.25 inch (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.20 to 0.30 inch (5.00 to 10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.125 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\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.453 inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0.0595 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: 1113527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739295940914,"sku":"1113527","price":322.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afc11e0f46d9584fb25bbd021b9eb383.jpg?v=1788812794","url":"https:\/\/voomisupply.com\/products\/kennametal-1113527-nr4125-k68-carbide-grooving-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
