Kennametal 2599539 Grooving Insert KC5010 Tialn Carbide

Product Description

The KENNAMETAL 2599539 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries the KC5010 grade with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability across a range of workpiece materials. The insert features a left-hand orientation, a 4.78 mm (0.1882 inch) cutting width, and a maximum depth of cut of 12.70 mm (0.500 inch). The full-radius geometry measures 2.39 mm (0.0941 inch) at the corner, and the neutral rake promotes balanced cutting forces. Machinists and CNC operators working in production turning environments install this insert as a direct replacement in compatible Top Notch toolholders.

This insert is suited for grooving operations in both light and moderate production environments. The KC5010 grade with TiAlN coating performs well on steel, cast iron, and similar materials graded C3 and C4. The NRD insert style fits into Top Notch series seat size 4 toolholders with a 55-degree included angle. It is sold individually per package with a minimum order quantity of 5 units, making it appropriate for shop stock replenishment on active turning programs.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the toolholder secured before seating or removing the insert. Use the appropriate torx or clamping screw specified for the Top Notch toolholder to achieve proper insert retention — do not overtighten or substitute fasteners. Inspect the insert seat and clamping components for wear or debris before installation to ensure correct seating and repeatable tool geometry.
