.045 Ball End Mill – 4 Flute

I've been cutting rounded slots in aluminum plate and the 4 flutes leave a noticeably cleaner finish than the 2 flute bits I used before. The .045 tip holds up fine on shallow passes, just don't push it too hard.

Picked this up for engraving curved details in aluminum and the round tip leaves a really clean finish with no sharp corners. The .045 tip is small enough for fine work but hasn't snapped on me yet.

Picked this up for engraving curved details on aluminum and the round tip leaves a much smoother radius than my old flat mill. The four flutes clear chips well, though I did manage to snap one on a deep pass when I got impatient. Still a solid cutter for the price.
