Kennametal 2599496 Grooving Insert NR3031 KC5010 Carbide

Product Description

The KENNAMETAL 2599496 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the NR3031 insert style in the Top Notch series, this left-hand insert features a TiAlN Physical Vapor Deposition (PVD) coating in Manufacturer Grade KC5010, providing wear resistance in a range of ferrous and non-ferrous workpiece materials. The cutting width measures 1.58 mm and the maximum depth of cut reaches 2.39 mm. A full corner radius of 0.79 mm promotes smooth chip flow and consistent surface finish. This insert is handled and installed by machinists and tooling technicians in production and job-shop turning environments.

This insert fits turning applications requiring controlled, narrow grooving or cutoff work where left-hand tool orientation is required. The Top Notch series is a widely recognized Kennametal tooling platform used in both light-duty finishing and moderate stock-removal grooving scenarios. The KC5010 grade with TiAlN coating is suited for dry or minimal-coolant cutting conditions. With a neutral rake geometry and a 55-degree included angle, this insert addresses applications where workpiece geometry or machine clearance favors a left-hand approach. Typical users include CNC lathe operators and tooling setters in contract machining, aerospace component production, and general precision turning shops.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing any insert. Ensure the toolholder pocket and clamping surfaces are clean and free of chips or debris before inserting. Do not exceed the maximum depth of cut rating for this insert size, and verify that the toolholder is rated for left-hand insert geometry before mounting.
