Kennametal 2599761 Grooving Insert NG2031 KC5025 Carbide

Product Description

The KENNAMETAL 2599761 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving operations on CNC lathes and turning centers. It carries the KC5025 manufacturer grade with a PVD-applied TiAlN coating, giving it strong wear resistance and heat tolerance in demanding cutting environments. The insert features a 0.79 mm cutting width, a maximum depth of cut of 1.27 mm, a 0.09 mm corner radius, and a neutral rake geometry. Configured for right-hand operation, it suits machinists and tool-and-die professionals working to tight tolerances on small-diameter grooves in steel and similar materials.

This insert is intended for use in light-duty grooving, parting, and profiling applications where dimensional accuracy and surface finish are critical. The NG-style insert fits Top Notch compatible toolholders and is well-suited to production turning in job shops, aerospace component machining, and precision part manufacturing. Its metric sizing designation of 2031 and the included angle of 55 degrees define its geometry class within the Top Notch platform. The TiAlN coating supports elevated cutting speeds and extends tool life compared to uncoated carbide in ferrous material grades.

Key Features

• KC5025 grade solid carbide substrate with PVD TiAlN coating for wear and heat resistance
• 0.79 mm cutting width for narrow, precise groove profiles
• 1.27 mm maximum depth of cut suits shallow grooving and profiling passes
• Neutral rake geometry with 0.09 mm corner radius for controlled chip formation
• Right-hand insert orientation for standard OD turning setups
• Top Notch series NG insert style for compatibility with dedicated toolholders

Compatibility

Designed for use in Top Notch series NG-style toolholders. Specific compatible holder models were not provided in the available product data; consult the KENNAMETAL Top Notch toolholder selector to confirm fitment for the NG2031 insert size.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine fully stopped and the spindle locked out per facility lockout/tagout procedures. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Inspect the toolholder pocket for wear, chips, or debris before seating a new insert. Do not exceed the maximum depth of cut rating for this insert geometry.
