Ingersoll Cutting Tools 5522843 Turning Insert CNMG432EM

Product Description

The INGERSOLL CUTTING TOOLS 5522843 is a CNMG-style solid carbide turning insert designed for negative-rake external turning operations. Coated with AlTiN and TiN via a PVD process, this insert is engineered for cutting stainless steel, steel, and super-alloys including titanium. The 80-degree diamond insert shape provides two usable cutting edges per side for a total of four cutting edges. With a 0.508-inch insert length and a 0.5-inch inscribed circle, it fits standard CNMG 432 toolholders. The EM chip breaker geometry controls chip flow in medium-depth finishing and semi-finishing passes.

This insert is used in CNC turning centers and manual lathes in both industrial and job-shop environments. The TT9080 grade with PVD-applied AlTiN and TiN coating is suited for interrupted and continuous cuts in stainless steel and super-alloy components where heat resistance and edge stability are critical. It is installed by machinists and CNC operators in production and maintenance machining applications. The neutral hand orientation makes it compatible with both right-hand and left-hand toolholder configurations without modification.

Key Features

• TT9080 PVD-coated grade with AlTiN and TiN coating for thermal and wear resistance
• 80-degree diamond insert shape (C) with negative rake and 0-degree relief angle (N clearance code)
• EM chip breaker geometry optimized for medium finishing and semi-finishing depths of cut
• Maximum depth of cut of 0.200 inches for controlled material removal
• Four total cutting edges extend tool life and reduce insert cost per edge
• Neutral hand insert fits both right-hand and left-hand CNMG 432 toolholders

Compatibility

Designed as an OEM-style replacement for CNMG 432 insert size code toolholders. ISO code CNMG120408EM TT9080. ANSI code CNMG432EMTT9080. Compatible with clamp-style CNMG toolholders accepting a 0.5-inch inscribed circle, 3/16-inch thick diamond insert.

Installation Notes

Installed by machinists and CNC operators using standard insert clamp toolholders rated for CNMG 432 geometry. Power down and lock out the machine before seating or rotating the insert. Inspect the insert seat and shim for damage or debris before clamping. Follow the toolholder manufacturer torque recommendations for the clamp screw to avoid insert fracture or seat damage.
