What is the difference between a regualar drill press and one of those
"magnetic" drill press. Does the "magnetic" term refer to the type of motor
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.

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
Specialist, expensive piece of gear. If you need one enough to buy
one, you wouldn't generally have to ask what it is...
