Kennametal 2598813 Grooving Insert NG3189 KC5010 Carbide

Product Description

The KENNAMETAL 2598813 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving operations on CNC lathes and turning centers. Manufactured to insert style NG with a size designation of 3189, it features a TiAlN coating applied via a PVD process, which provides wear resistance and extended tool life in a wide range of workpiece materials. The insert has a left-hand orientation, a cutting width of 4.80 mm (0.189 inches), and a maximum depth of cut of 3.81 mm (0.150 inches). Material grade is rated C3 and C4, making it suitable for machining cast iron, non-ferrous metals, and general-purpose alloy steels. This insert is installed and managed by machinists and tooling technicians in production and job-shop environments.

The 2598813 is used in external and internal grooving applications on turning equipment where controlled depth and consistent groove geometry are required. Its neutral rake geometry and 0.57 mm (0.0225 inch) corner radius suit applications demanding accurate groove profiles in medium to finishing cuts. The insert fits Top Notch series toolholders designed for NG-style inserts. It is sold individually but must be ordered in multiples of 5.

Key Features

• TiAlN coating via PVD process for elevated wear and heat resistance
• 4.80 mm cutting width with a maximum depth of cut range of 3.00 to 4.00 mm
• Left-hand insert orientation for compatible toolholder setups
• Neutral rake geometry for stable, predictable cutting action
• 0.57 mm corner radius for controlled groove edge geometry
• Solid carbide substrate in grades C3 and C4 for broad material compatibility

Compatibility

Designed for use in Top Notch series toolholders accepting NG-style grooving inserts with an insert size designation of 3189. Confirm toolholder bore, clamping style, and insert seat dimensions before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a full stop, locked-out condition. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer - do not use generic fasteners. Inspect the insert seat for chips or debris before seating the insert. Verify correct insert orientation and hand before resuming cutting operations.
