200 Series

Tool 200i500Z040C

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 demanding aluminum cut and watch the corner chip or microcrack before the job's done.

The 200 Series carries a 0.04" corner radius specifically to distribute cutting forces across more carbide.
Corner radius extends tool life by reducing stress concentration at the most vulnerable point while maintaining good corner definition in your parts.
Three flutes balance chip load per tooth against feed rate.
Lighter individual cuts mean less heat generation and reduced tendency for aluminum to weld to the edge.
This 0.5" diameter version runs TiB₂ coating for the demanding passes where standard uncoated tools start to struggle.
TiB₂ stays chemically inert with aluminum while adding hardness where the cutting edge needs it most.
