200 Series

Tool 200i313C

Built-up edge shows up fast on small diameter work. The 5/16" diameter doesn't give you much room for error when heat builds up, and aluminum will weld to the cutting edge before you know the setup is wrong.

The 200i313C runs a 3-flute configuration that keeps chip load manageable while maintaining your programmed feed rates.
High helix geometry moves chips out before they can stick or reheat.
The TiB₂ coating adds hardness without the aluminum affinity that makes AlTiN problematic on these materials - titanium-based coatings tend to grab aluminum, while the boride layer stays chemically neutral.
Corner radius sits at R0.006", which strengthens the cutting edge enough to handle interrupted cuts without going dull on entry.
Built for aluminum, copper, and plastics where chip welding kills surface finish.
