you will need a varable speed spindle to do any kind of serious drilling in metals.What is the desired purpose of the drill you are placing on the machine, drill holes in aluminun,steel...? what size drills do you want to drill? I have seen the drilling head from a milwaukie mag base drill press mounted on the gantry. It depends on what you intend to use the drill for in the first place. The air spindle you linked to looks like it may work....just thought I would pose some questiions for thought. |
