Tried a 0.5mm pass on finish and got a mirror on 6061
Been running the same feeds for years on aluminum. Switched to a 0.5mm depth of cut with a 3 flute carbide end mill. Surface finish came out like glass. No sanding needed. Anyone else dial in tiny passes to skip the polish step?

Small passes like that really let the cutter sing.

42 grit paper usually makes it rasp instead of sing.
