Ingersoll Cutting Tools 5522322 Carbide Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 5522322 is a CNMG432RGP TT8115B carbide turning insert designed for use in CNC and manual lathe toolholders requiring a diamond-shaped insert with an 80-degree included angle. Coated via CVD with Al2O3 and TiCN titanium nitride layers, the TT8115B grade delivers wear resistance and thermal stability during steel turning operations. The insert features a negative rake geometry, a 0.0310-inch corner radius, and a 0.5000-inch inscribed circle, providing four usable cutting edges per insert. It is installed and indexed by licensed machinists and CNC operators in production and job-shop environments.

This insert is suited for turning steel workpieces in both roughing and finishing passes where a CNMG-style seat and clamp-style holding method are used. The RGP chip breaker geometry is configured for steel applications, helping manage chip flow during continuous and interrupted cuts. With a maximum depth of cut of 0.2360 inches and an insert thickness of 0.1870 inches, it fits standard CNMG 432-size toolholders common in production turning cells and manual engine lathes.

Key Features

• CVD-applied Al2O3 and TiCN titanium nitride coating for thermal and abrasion resistance
• TT8115B manufacturer grade optimized for primary use on steel workpieces
• RGP chip breaker geometry for controlled chip flow in steel turning
• Four cutting edges per insert for extended tool life per unit
• Negative rake, 80-degree diamond shape with CNMG clamp-style holding
• 0.0310-inch corner radius balances edge strength and surface finish

Compatibility

Designed for use in CNMG 432-style clamp toolholders with a matching seat and clamp arrangement. ISO designation for this insert is CNMG120408RGP TT8115B. Primary workpiece material is steel (ISO material code S).

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully against the toolholder pocket before tightening the clamp; an improperly seated insert can fracture under cutting load. Follow the toolholder manufacturer torque guidance for the clamp screw and inspect the pocket and clamp for wear or damage each time the insert is indexed.
