Kennametal 2599743 Grooving Insert NG2041 KC5010 Carbide

Product Description

The KENNAMETAL 2599743 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 KC5010 manufacturer grade with a PVD-applied TiAlN coating, delivering wear resistance and thermal stability in interrupted and continuous grooving cuts. The insert features a 1.04 mm cutting width and a maximum depth of cut of 1.27 mm, making it well-suited for fine grooving work where dimensional accuracy is critical. The right-hand orientation and neutral rake geometry support consistent chip control. Machinists and CNC operators install this insert as a direct component of a Top Notch toolholder system.

This insert is intended for use in metalworking applications involving ferrous and non-ferrous materials classified under material grades C3 and C4. The NG insert style and 2041 insert size target operations on smaller-diameter workpieces where tight groove tolerances are required. Typical installations are found in production turning environments, including job shops and manufacturing facilities running high-volume part programs. The 55-degree included angle and 3-degree lead angle contribute to controlled entry geometry on precision turned components.

Key Features

• KC5010 grade solid carbide with PVD TiAlN coating for extended tool life in grooving applications
• 1.04 mm cutting width for precise, narrow groove profiles
• Maximum depth of cut of 1.27 mm, with a rated range up to 2.00 mm
• Right-hand, neutral rake geometry for consistent chip formation and dimensional control
• 0.09 mm corner radius minimizes stress concentration at groove base
• Top Notch series insert style for direct compatibility with Top Notch toolholding systems

Compatibility

Designed for use with Top Notch series toolholders accepting NG-style inserts in the 2041 insert size. Confirm toolholder designation accepts right-hand, neutral rake NG inserts before installation.

Installation Notes

This insert is installed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer — do not over-torque the clamping screw. Inspect the toolholder pocket for debris or wear before seating the new insert to ensure proper seating and repeatability.
