.093 Ball End Mill – 4 Flute

I picked this up mainly for engraving aluminum plates and the ball tip leaves a much smoother groove than my old square cutter. The .093 tip is small enough for fine detail but the 1/8 shank still fits my standard collet. Ran it through a couple of stainless parts too and it held up fine.

Cut a batch of engraving on hardened stainless and the .093 ball tip held its edge the whole time, no chatter at all on my little 1/8 shank setup. Finish was smooth enough that I barely had to deburr.

The 4 flutes really help clear chips when I'm profiling aluminum, way less chatter than the 2-flute bits I used before. Ball tip leaves a nice smooth radius on my engraved lettering too.
