Ingersoll Cutting Tools 5520806 Turning Insert CNMG432ML

Product Description

The INGERSOLL CUTTING TOOLS 5520806 is a CNMG432ML turning insert in grade TT9225, manufactured from solid carbide with a multilayer CVD coating of TiCN, Al2O3, and TiCN. The 80-degree diamond shape provides a strong cutting edge geometry suited for moderate to heavy material removal. With a 0.5 inch inscribed circle, a 0.508 inch length, and a 0.031 inch corner radius, this insert delivers consistent geometry across all four cutting edges. The negative rake and ML chip breaker geometry work together to control chip formation in demanding applications. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.

This insert is engineered for turning stainless steel, super-alloys, and titanium - workpiece material codes M and S. It fits toolholders designed for CNMG-style inserts with a clamp holding method and N clearance code. The ML chip breaker is optimized for light-to-medium depth cuts, with a maximum depth of cut of 0.138 inches. It is appropriate for both roughing passes at reduced feeds and finishing passes where edge stability is critical in high-temperature alloy turning operations.

Key Features

• Solid carbide substrate with multilayer CVD TiCN / Al2O3 / TiCN coating for heat and wear resistance
• 80-degree diamond insert shape (Shape Code C) provides a strong nose angle for interrupted and continuous cuts
• ML chip breaker geometry controls chip flow in stainless steel and super-alloy turning
• Four cutting edges per insert reduce tooling cost per edge
• Negative rake design increases edge strength and supports heavier chip loads
• ISO-compliant geometry - ISO code CNMG120408ML TT9225

Compatibility

Designed for use in CNMG-style clamp-type toolholders accepting a 1/2 inch inscribed circle insert with N clearance and M tolerance. Compatible workpiece materials are stainless steel and super-alloys including titanium per ISO material codes M and S.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torx or hex key to secure the clamp to manufacturer-specified procedure without over-torquing the locking screw. Inspect the insert seat and clamp pocket for chips or debris before seating to ensure proper insert support and prevent premature edge failure.
