200 Series

Tool 200i375C

Aluminum chips turn into welded mess when heat builds faster than evacuation can handle. You get that dragged finish and shortened tool life because the material wants to stick, not shear cleanly.

The 200i375C runs three flutes at 3/8" diameter with TiB₂ coating for aluminum, copper, and plastics.
Three flutes distribute chip load across more cutting edges while the high helix geometry moves material out of the cut zone before adhesion starts.
TiB₂ coating adds hardness without the aluminum affinity that makes AlTiN coatings problematic on these materials.
The R0.006" corner radius strengthens the cutting edge against chipping while maintaining the sharp geometry needed for clean entry.
This size handles moderate depths of cut in aluminum components where surface finish matters more than maximum material removal rates.
