Kennametal 2599529 Grooving Insert NG3189 KC5025 Tialn

Product Description

The KENNAMETAL 2599529 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which delivers high hardness and oxidation resistance at elevated cutting temperatures. This insert is sized to the NG3189 Top Notch series profile with a 4.8 mm cutting width and a maximum depth of cut of 3.81 mm. The left-hand orientation suits specific toolholder configurations where the cut is made from left to right. Machining professionals and CNC setup technicians install and index this insert as part of routine tooling maintenance in production turning environments.

This insert is suited for external grooving, undercut, and light parting operations on lathes and multi-axis turning centers. The KC5025 grade with TiAlN finish performs well on steels and cast irons where material grades C2 and C6 apply. The neutral rake geometry and 55-degree included angle support consistent chip control in medium to high production runs. It is intended for use with compatible Top Notch series toolholders that accept the NG3189 insert style.
