Kennametal 2599522 Grooving Insert NG3062 KC5025 Carbide

Product Description

The KENNAMETAL 2599522 is a solid carbide grooving insert designed for precise external and face grooving operations on CNC lathes and turning centers. This insert carries the KC5025 manufacturer grade with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability during interrupted cuts and continuous grooving passes. The left-hand cutting orientation and 1.58 mm cutting width make it suitable for close-tolerance groove profiles. The neutral rake geometry and 0.19 mm corner radius support consistent chip formation across a range of ferrous and non-ferrous workpiece materials. Machinists and toolroom professionals install this insert into compatible Top Notch series toolholders.

This insert belongs to KENNAMETAL's Top Notch series, which is commonly used in production turning environments where repeatable groove geometry and secure insert indexing are required. The NG insert style with size designation 3062 fits Top Notch compatible toolholders configured for left-hand grooving. Typical applications include grooving operations on bar stock, shaft components, and turned parts where groove width and depth tolerances are critical. The insert is sized and graded for general-purpose grooving in both light production and job-shop environments.

Compatibility

Designed for use in Top Notch series toolholders accepting NG-style inserts in size 3062 with a left-hand cutting configuration. Verify toolholder pocket specifications before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or toolroom professional with the machine powered down and the spindle locked. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not over-tighten the clamping screw. Inspect the insert seat for chips or debris before seating the insert. Confirm left-hand orientation and toolholder compatibility before initiating a cut.
