It carries the KC730 grade with a PVD-applied TiN coating, delivering wear resistance and edge stability across a range of workpiece materials. The insert features a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm, making it well suited for narrow, precise grooves. The full-radius geometry with a 0.79 mm corner radius and neutral rake promotes smooth chip flow and consistent surface finish. Right-hand orientation is specified for standard turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metal-cutting environments where tight groove tolerances are required. It is rated for material grades C2, C3, and C4, covering a broad range of cast irons and non-ferrous materials as well as general steel applications. The Top Notch series toolholder system provides the mating seat geometry for this NR2031 insert style. It is typically installed by machinists and CNC operators in production turning shops, job shops, and precision machining facilities. The insert size designation is 2031, and the MSC manufacturer reference number is NR2031R\/L.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with KC730 grade for durability in interrupted and continuous grooving cuts\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating improves surface hardness and reduces built-up edge formation\u003c\/li\u003e\n  \u003cli\u003e1.58 mm cutting width supports narrow groove applications\u003c\/li\u003e\n  \u003cli\u003eFull radius geometry with 0.79 mm corner radius for consistent groove profile\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and 55-degree included angle for stable, balanced cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation for standard lathe setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders that accept the NR2031 insert style.

The machine must be powered down and the spindle fully stopped before seating or removing inserts. Use the appropriate torx or clamp screw specified by the Top Notch toolholder to secure the insert at the correct clamping torque per the toolholder manufacturer documentation. Inspect the insert seat and clamp for debris or damage before each insert change to ensure proper seating and safe cutting performance.\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: 2031\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\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: TiN\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.58 mm (0.0622 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 mm to 3.00 mm (0.1000 to 0.1500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0311 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.2190 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\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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: 0.0661 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: 1112962\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731069501746,"sku":"1112962","price":241.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a140b8bda5645e0b81276c419ec65b8f.jpg?v=1788726566","url":"https:\/\/voomisupply.com\/products\/kennametal-1112962-grooving-insert-nr2031-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
