Kennametal 2599538 Grooving Insert NRD4094 KC5010 Carbide

Product Description

The KENNAMETAL 2599538 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. Running in the Top Notch series, this insert carries the KC5010 grade with a PVD-applied TiAlN coating, which supports extended tool life in steel and cast iron applications. The cutting width is 4.78 mm (0.1882 inches), the maximum depth of cut is 12.70 mm (0.5000 inches), and the full-radius corner measures 2.39 mm (0.0941 inches). The neutral rake geometry and right-hand orientation suit standard OD grooving setups. Installation and use are intended for machinists and toolroom professionals operating compatible Top Notch toolholders.

This insert is suited for external grooving, profiling, and light parting on turning equipment where a metric 4094 insert size is specified. The KC5010 grade targets general-purpose machining of steels and harder materials within the C3 and C4 material grade range. The insert style is NRD with a 55-degree included angle, making it appropriate for applications requiring a defined groove width and full-radius profile. It is sold individually per package with a minimum order quantity of 5 units.
