Kennametal 1818460 Grooving Insert NR3031K KC5010 Carbide

Product Description

The KENNAMETAL 1818460 is a solid carbide grooving insert designed for precision external grooving and profiling operations on CNC lathes and turning centers. Featuring a TiAlN PVD coating and KC5010 grade carbide substrate, this insert delivers wear resistance and thermal stability in demanding cut conditions. The NR3031K insert style provides a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm, with a full corner radius of 0.79 mm. The positive rake geometry and K-style chip breaker promote efficient chip evacuation in a wide range of workpiece materials. Machining professionals and CNC operators install this insert as part of the Top Notch series tooling system.

This insert is suited for grooving applications in both production and job-shop environments where consistent dimensional accuracy is required. The right-hand orientation and metric sizing make it a direct fit for Top Notch series grooving toolholders used on manual and CNC turning equipment. It is appropriate for machining steel, alloy steel, and cast iron workpiece materials classified under material grades C3 and C4. The insert is sold individually but requires a minimum order quantity of 5 units per transaction.

Installation Notes

Installation is performed by trained machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before handling or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the Top Notch toolholder manufacturer — do not overtighten the clamping screw by hand estimation alone. Inspect the insert pocket and clamping seat for chips or damage before seating the new insert.
