Kennametal 2599572 Grooving Insert NG2031 KC5010 Left Hand

Product Description

The KENNAMETAL 2599572 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Manufactured to the NG2031 insert style in the Top Notch series, this left-hand insert carries a PVD-applied TiAlN coating and the KC5010 manufacturer grade. It delivers a cutting width of 0.79 mm (0.0311 inches) and a maximum depth of cut of 1.27 mm (0.0500 inches), making it suited for narrow, controlled grooving passes where dimensional accuracy is critical. Installed by machinists and CNC operators, this insert is a direct-replacement consumable for toolholders configured for Top Notch NG-style inserts.

This insert is intended for use in metalworking applications requiring consistent groove geometry in ferrous and non-ferrous materials. The KC5010 grade with TiAlN coating performs well in applications demanding wear resistance and thermal stability. The left-hand orientation suits toolholders configured for left-hand cutting direction. The Top Notch series is a widely used indexable grooving platform, and this insert fits standard Top Notch NG toolholders used in production turning environments, job shops, and maintenance machining operations.

Installation Notes

This insert is installed and indexed by trained machinists or CNC operators. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or clamping key specified for the Top Notch toolholder to secure the insert without over-torquing the clamp. Inspect the toolholder seat for chips or debris before seating the new insert to ensure proper contact and dimensional repeatability.
