Ingersoll Cutting Tools 6402239 Grooving Insert TT9080

Product Description

The INGERSOLL CUTTING TOOLS 6402239 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Running in the TQJ27 series, this right-hand insert carries a TT9080 manufacturer grade and features a PVD-applied TiAlN and TiN dual coating for extended tool life in demanding cutting environments. The cutting width is 0.079 inches with a corner radius of 0.0040 inches, making it well suited for fine, accurate groove profiles. A positive rake geometry and J-style chip breaker promote clean chip evacuation and reduce cutting forces. Licensed machinists and CNC operators install this insert as part of a screw-clamped toolholder system.

This insert is intended for grooving steel and hard materials in production turning applications. The TQJ27 series fits screw-type toolholders that accept TQJ-style inserts. Maximum depth of cut falls within the 0.2000 to 0.3000 inch range, with a nominal maximum depth of cut of 0.2520 inches, making it appropriate for moderate-depth grooving passes in both roughing and finishing scenarios. It is suitable for residential shop, job shop, and industrial production environments where steel and hard-material components require consistent groove geometry.

Compatibility

Designed for use with TQJ27 series screw-clamped grooving toolholders that accept TQJ-style inserts. Compatible primary workpiece materials include steel and hard materials as indicated by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified method without overtightening. Inspect the insert pocket and seating surfaces for debris or damage before installing a new insert to ensure proper seating and tool life.
