Ingersoll Cutting Tools 6400286 Grooving Insert TT7220

Product Description

The INGERSOLL CUTTING TOOLS 6400286 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the TT7220 manufacturer grade with a PVD coating process, delivering wear resistance and thermal stability during interrupted or continuous cuts. The insert features a 0.1181-inch (3.00 mm) cutting width, a neutral hand orientation, and a positive 7-degree rake angle. A full corner radius of 0.0590 inches reduces stress concentration at the groove floor. Machinists and CNC turning specialists install this insert into T-Clamp Ultra Plus toolholders for grooving applications on steel workpieces.

This insert is rated for steel as its primary workpiece material (ISO material code P), making it well suited for external and internal grooving on low-alloy and medium-carbon steels in both production and job-shop environments. The T-Clamp Ultra Plus series uses a clamp-style holding method that provides rigid seating and repeatable indexing. The insert style is TDT with size code 300E150. It is a single-use, non-multi-use insert intended for indexing rather than resharpening. The T chip breaker geometry helps control chip curl and evacuation in tight grooving profiles.

Key Features

• Solid carbide substrate with PVD coating for extended tool life on steel
• 0.1181-inch (3.00 mm) cutting width with full corner radius of 0.0590 inches
• Positive 7-degree rake angle reduces cutting forces on steel workpieces
• Neutral hand orientation fits left- or right-hand toolholder setups
• T chip breaker geometry promotes controlled chip formation in narrow grooves
• Clamp-style insert holding for secure, repeatable seating in T-Clamp Ultra Plus holders

Compatibility

Designed for use with INGERSOLL T-Clamp Ultra Plus series toolholders accepting TDT-style inserts with size code 300E150. Primary application is grooving steel workpieces (ISO P material group).

Installation Notes

This insert is installed and indexed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate clamp key or torx driver specified by the toolholder manufacturer to seat the clamp securely. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper contact and prevent premature edge failure.
