Ingersoll Cutting Tools 6402194 Grooving Insert TQJ27

Product Description

The INGERSOLL CUTTING TOOLS 6402194 is a solid carbide grooving insert engineered for precision grooving and parting operations on CNC lathes and turning centers. Built to the TQJ27 series standard, it features a TiAlN and TiN PVD coating applied over a carbide substrate in manufacturer grade TT9080. The insert carries a neutral hand orientation with a positive rake geometry and a J-style chip breaker. Cutting width is 0.03 inches, and the maximum depth of cut reaches 0.098 inches, with a rated depth-of-cut range of 0.075 to 0.10 inches. Machinists and CNC tooling technicians working in production turning environments will find this insert suited to demanding stock removal on steel and hard materials.

This insert is intended for grooving applications where consistent chip control and coating durability are critical. Its primary workpiece materials are steel and hard materials, making it appropriate for production turning shops handling alloy steel components, hardened parts, and similar ferrous stock. The screw-holding method locks the insert securely in a compatible TQJ-style toolholder, maintaining positional accuracy through repeated passes. The 90-degree lead angle supports straight-wall groove profiles. This insert is sold individually and is rated for multi-use service life.

Key Features

• TT9080 grade solid carbide substrate with PVD-applied TiAlN and TiN dual coating for heat and wear resistance
• J-style chip breaker promotes controlled chip evacuation during grooving on steel and hard materials
• Neutral hand orientation with positive rake geometry reduces cutting forces
• Screw-clamp holding method provides rigid, repeatable insert seating in TQJ toolholders
• Maximum depth of cut of 0.098 inches with a working range of 0.075 to 0.10 inches
• 90-degree lead angle delivers clean, perpendicular groove walls

Compatibility

Designed for use with TQJ27 series toolholders that accept the TQJ insert style. Confirm toolholder pocket specifications match the TQJ insert geometry and screw-clamp mounting before installation.

Installation Notes

Insert installation and replacement should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Use the manufacturer-specified torx or hex key to tighten the clamping screw; do not overtighten or use impact tools on the insert screw. Inspect the toolholder pocket for wear or debris before seating a new insert.
