200 Series

Tool 200i250S030C

Tight corners in aluminum work reveal every mistake. Sharp edges chip out, leaving witness marks and dimensional drift that turns precision parts into scrap. The problem gets worse at smaller diameters where deflection amplifies every imperfection.

The 200i250S030C brings a 0.030" corner radius to quarter-inch aluminum cutting.
That radius distributes cutting forces across more material, reducing the stress concentration that leads to chipping.
Three flutes maintain feed rates while keeping individual tooth loads manageable.
The combination that prevents built-up edge formation before it starts.
TiB₂ coating handles the demanding passes where aluminum wants to weld to the tool.
The coating stays chemically inert against aluminum adhesion while adding wear resistance for longer tool life.
High helix geometry moves chips out fast, before heat builds up.
