200 Series

Tool 200i750X125C

Aluminum work hardens under pressure, and sharp corners concentrate stress exactly where you don't want it. Push a standard square end mill through a heavy cut and watch the corner chip or the workpiece tear instead of shear.

The 200 Series features a 0.125" corner radius that distributes cutting forces across more edge length.
This distributes load and reduces the pressure spike that causes work hardening in aluminum alloys.
Three flutes maintain surface finish quality while keeping individual chip loads manageable.
Each tooth takes less material per revolution, which prevents the heat buildup that leads to welding.
TiB₂ coating adds wear resistance for demanding operations without the aluminum adhesion problems you get with AlTiN.
High helix geometry moves chips out before they can reweld to the work or clog the flutes.
