Horizontal Mill Spindle Direction? The Home Machinist!
#0183;#32;It would be best to have the arbor spin as suggested above, because then you can use end mill holders and drill chucks and do a great number of things that aren''t possible with a spindle turning in the ''wrong'' direction. I use my horizontal with an end mill far more than with an arbor mounted cutter. But then again, I don''t have a vertical mill.
