Sumitomo 144W424 Milling Insert ACM300 Solid Carbide

Product Description

The SUMITOMO 144W424 is a solid carbide coated milling insert designed for precision metal removal in demanding cutting applications. It features a parallelogram (AXMT) insert style with an 85-degree included angle and an 11-degree relief angle. The insert carries the ACM300 manufacturer grade with a PVD coating process, providing wear resistance and thermal stability during interrupted and continuous cuts. It is compatible with the WEX3000 cutter series and ships as an individual insert, with a minimum order quantity of 10 pieces. The EH chip breaker geometry helps manage chip flow when cutting through tough workpiece materials.

This insert is engineered for use on stainless steel and superalloy workpieces, material code classifications M and S. It is suited for milling operations in aerospace, energy, and industrial manufacturing environments where tight tolerances and controlled tool life are required. The right-hand cutting configuration and maximum depth of cut of 0.5510 inches (14.00 mm) make it appropriate for face milling and shoulder milling setups using compatible WEX3000 toolholders. Installation is performed by qualified machinists and CNC setup technicians.

Compatibility

Designed for use with the WEX3000 cutter series. Primary workpiece materials are stainless steel and superalloys (material codes M and S). Verify toolholder seat geometry and insert size code 1235 before installation.

Installation Notes

Insert seating and torque should follow the toolholder manufacturer specifications for the WEX3000 series. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the appropriate Torx or hex key driver as specified by the toolholder documentation. Inspect the insert pocket seat for chips or debris before seating the new insert to avoid premature edge failure.
