Iscar 5569406 TNMG432-M3M IC807 Carbide Turning Insert

Product Description

The ISCAR 5569406 is a TNMG432-M3M IC807 carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a 60-degree triangular insert shape with a positive rake geometry and a 0.80 mm corner radius. The insert is coated with TiAlN and TiN using a PVD coating process under ISCAR's proprietary SumoTec designation, which enhances wear resistance and thermal stability at the cutting edge. With an inscribed circle of 12.70 mm and an insert length of 22.00 mm, it is suited for medium to moderate finishing and semi-finishing operations. Licensed machinists, CNC operators, and tooling specialists install this insert in compatible turning toolholders.

This insert is designed for right-hand turning applications and fits within ISCAR's Isoturn series toolholding system. It is rated for use across multiple primary workpiece material codes including H, K, M, P, and S, covering a broad range of ferrous alloys, stainless steels, heat-resistant superalloys, and non-ferrous materials. The M3M chip breaker geometry is optimized for general turning conditions where controlled chip formation is essential. Maximum depth of cut is 5.00 mm, making it appropriate for medium-stock removal passes in production turning environments.

Compatibility

Designed as an OEM-style replacement insert for TNMG-style right-hand turning toolholders within the ISCAR Isoturn series. Confirm toolholder seat size and clamping style before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer — do not over-torque the clamping screw. Inspect the toolholder seat for debris or damage before seating a new insert to ensure proper contact and edge stability.
