Kennametal 2599528 Grooving Insert KC5025 Carbide Tialn

Product Description

The KENNAMETAL 2599528 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the NG3189 insert style and offered in the KC5025 grade with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability in a range of workpiece materials. The cutting width is 4.8 mm and the maximum depth of cut is 3.81 mm, making it well suited for medium-depth grooving applications. The right-hand configuration and neutral rake geometry support predictable chip flow and consistent surface finish. Machinists and CNC operators working in production environments rely on this insert for repeatable results in ferrous and non-ferrous turning.

This insert fits the Top Notch series tooling system and is appropriate for use in both light and moderate grooving operations on shaft, bore, and face profiles. The NG insert style with a 55-degree included angle and a 0.57 mm corner radius supports clean groove geometry without full-radius profiling. It is suited for job shops and production turning operations handling general-purpose grooving tasks in steel and cast materials rated to material grades C2 and C6.

Compatibility

Designed for use with Top Notch series grooving toolholders accepting the NG3189 insert style. Refer to the MSC or manufacturer number NG3189R/L when cross-referencing compatible toolholder bodies.

Installation Notes

Insert replacement and seating should be performed with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp to the correct clamping torque per the toolholder documentation. Inspect the insert pocket for chips or debris before seating to avoid improper seating and premature edge failure. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
