Kennametal 2599531 Grooving Insert NR3031 KC5025 Carbide

Product Description

The KENNAMETAL 2599531 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. This insert carries the KC5025 manufacturer grade with a PVD-applied TiAlN coating, offering wear resistance and thermal stability in demanding cutting environments. It is configured for left-hand cutting with a neutral rake geometry and a full corner radius of 0.79 mm. With a cutting width of 1.58 mm and a maximum depth of cut of 2.39 mm, it suits fine grooving applications where dimensional accuracy is critical. Machinists and CNC operators install this insert into compatible Top Notch series toolholders.

This insert fits into the Top Notch series tooling system and is appropriate for external grooving, face grooving, and parting-off operations in production turning environments. It is suited for use on ferrous and non-ferrous materials within the C2 and C6 material grade classifications. The left-hand orientation makes it the correct selection for toolholders configured for left-hand approach grooving. Typical applications include precision component machining in aerospace, automotive, and general metalworking shops where tight groove tolerances are required.

Key Features

• Solid carbide construction with PVD TiAlN coating for extended tool life
• Cutting width of 1.58 mm for precise, narrow groove profiles
• Maximum depth of cut of 2.39 mm, within the 2.00 to 3.00 mm range classification
• Full corner radius of 0.79 mm for smooth groove floor geometry
• Left-hand insert orientation for compatible Top Notch series toolholders
• Neutral rake geometry suitable for a wide range of workpiece materials

Compatibility

Designed for use with Top Notch series grooving toolholders that accept NR3031 style inserts. Material grade classifications C2 and C6 define the recommended workpiece material range for this insert.

Installation Notes

This insert is installed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing any insert. Ensure the toolholder pocket is clean and free of chips or debris before installation to maintain proper insert seating and repeatability. Follow the toolholder manufacturer torque specifications for the clamping screw, as over-torquing can cause insert fracture.
