Kennametal 2598823 Grooving Insert NGD3189 KC5010 Carbide

Product Description

The KENNAMETAL 2598823 is a solid carbide grooving insert designed for precision grooving and turning operations on CNC lathes and turning centers. Built to the NGD3189 insert style in the Top Notch series, it carries a KC5010 manufacturer grade with a PVD-applied TiAlN coating for wear resistance at elevated cutting temperatures. The insert is left-hand oriented with a neutral rake geometry, a cutting width of 4.8 mm (0.189 inches), and a maximum depth of cut of 6.35 mm (0.250 inches). A corner radius of 0.57 mm (0.022 inches) and a 55-degree included angle complete the geometry. Machinists and CNC technicians install this insert in compatible Top Notch grooving toolholders for ferrous and non-ferrous workpiece applications.

This insert is suited for external grooving, parting, and profiling operations on CNC turning equipment in both production shop and job shop environments. The KC5010 grade with TiAlN coating performs well in interrupted cuts and at higher surface speeds where heat generation is a concern. The maximum depth of cut range spans 5.00 mm to 10.00 mm (0.200 inches to 0.300 inches), making it appropriate for moderate-depth grooving passes. It is sold individually but must be ordered in multiples of five units per order cycle.

Installation Notes

This insert is installed and replaced by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or clamping key specified by the toolholder manufacturer to seat the insert securely - do not overtighten by improvised methods. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper contact and repeatability.
