Kennametal 2599750 NG2125 KC5010 Grooving Insert Carbide

Product Description

The KENNAMETAL 2599750 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Built to the Top Notch series standard, this insert carries the KC5010 manufacturer grade with a PVD-applied TiAlN coating for extended tool life in steel and cast iron applications. The cutting width measures 3.18 mm (0.1252 inches) and the maximum depth of cut reaches 2.79 mm (0.1098 inches). A neutral rake geometry and right-hand orientation make it suitable for standard OD grooving setups. The corner radius is 0.19 mm (0.0075 inches), supporting fine surface finish requirements without a full-radius edge profile.

This insert is intended for use in industrial machining environments where consistent groove geometry and coating durability are critical. The NG2125 insert style seats into compatible Top Notch series toolholders used in production turning on CNC equipment. It is suited for machinists and tooling technicians working in job shops, production floors, and contract manufacturing settings. The insert falls within the C3 and C4 material grade classification, indicating suitability for machining hardened and general-purpose ferrous materials.

Compatibility

Designed for use with Top Notch series toolholders accepting the NG-style insert seat. Confirm toolholder insert pocket dimensions match the NG2125 insert size before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a full stop, de-energized state. Use the manufacturer-recommended torque driver for the clamping screw to secure the insert without over-torquing the seat. Inspect the toolholder pocket for chips or debris before seating the insert. Follow your facility safety plan and machine tool manufacturer guidelines when indexing or replacing cutting inserts.
