    Drill Speeds - Curious Inventor

    How to choose the right drill speed. Quick Summary: Some approximate starting advice is to set the spindle speed between 700-1000 rpms for steel, above 2000 for aluminum, and slow down from there if you get discolored chips or heavy drill bit wear.In most cases the drill press will not be able to supply enough power or speed to follow the below recommendations.
