Drill Press Question

What is the difference between a regualar drill press and one of those compact "magnetic" drill press. Does the "magnetic" term refer to the type of motor is has or something else.
I see comments on these small magnetic press's like "The new magnetic design increases the drill point breakaway to 820 lb". WTH are they talking about?

" magnetic" refers to the base of the drill. It is a powerful electro-magnet that holds the drill usually to a steel beam or plate. In this case capable of 820 lbs of drilling force It would take 820 lbs. of force to dislodge the magnet and thus the drill's cutting implement from the metal cutting surface. You can set a mag drill on steel where you want a hole, engage the magnet and drill away with standard bits or roto-broach cutters. Most people don't have one in their garage's at home.

thanks for the info. now that I think of it, it makes perfect sense. so I take it that you are pretty much screwed if you are trying to drill aluminum since magnets do no not stick to it?

Unless you put a piece of 6 gauge steel on the other side. The strength of the magnet would clamp the aluminum between the magnet and the steel. Wouldn't it? Depending on the thickness of the aluminum?

Only if you can clamp it to something. THey are mainly used for drilling steel plate, where it is easier to take the drill to the work. Specialist, expensive piece of gear. If you need one enough to buy one, you wouldn't generally have to ask what it is...
