Kennametal 2599536 Grooving Insert NRD4062 KC5010 Carbide

Product Description

The KENNAMETAL 2599536 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Running in the Top Notch series, this NRD-style insert carries a KC5010 grade substrate with a PVD-applied TiAlN coating, delivering hardness and heat resistance suited for interrupted cuts and finishing passes. The cutting width measures 3.18 mm (0.1252 inches), with a maximum depth of cut of 6.35 mm (0.25 inches). A full radius profile with a 1.59 mm corner radius and a neutral rake geometry round out the cutting edge geometry. This insert is installed by machinists and CNC setup technicians working in production or job-shop turning environments.

This insert is suited for both light finishing and moderate material removal in grooving applications. The KC5010 carbide grade, rated C3 and C4, performs across a range of workpiece materials including steels and cast irons at controlled cutting parameters. The Top Notch series uses a positive-locking insert seat size 4, which mates with compatible Top Notch toolholders. The included angle of 55 degrees supports V-profile and relief groove geometries. This is a single-use, non-reversible insert; it is right-hand oriented and not a multi-use tool.

Installation Notes

This insert is installed and replaced by machinists or CNC technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified for the Top Notch toolholder to secure the insert; do not overtighten by hand. Inspect the insert seat for chips or debris before seating a new insert to ensure proper contact and repeatability.
