200 Series

Tool 200i250L030C

Aluminum sticks to sharp corners. Quarter-inch roughing passes in 6061 will load up a square corner end mill fast, especially when you need to push feed rates to keep heat from building.

The 200i250L030C handles this with a 0.03" corner radius that distributes cutting forces across more carbide.
Three flutes maintain surface finish while keeping individual chip loads manageable.
Each tooth does less work per revolution, which prevents the heat buildup that causes aluminum to weld to the tool.
The radius also extends tool life in interrupted cuts where sharp corners would chip.
TiB₂ coating adds wear resistance for longer runs in aluminum, copper, and plastics without the aluminum affinity problems you get with AlTiN.
High helix geometry moves chips out before they can cause trouble.
