Milwaulee makes a 1.25" super hole shooter, model 2404-1, Metabo makes a model 
6030 1.5" drill.  I am sure there are many others, specially if you include the 
rotary hammer drills.

Well, not electric, but we use hand held air drills to drill up to 3" in

Biggest electric I've seen is a 1" Milwaukee, a local farmer owns it, uses it
to 'crank up' his silo unloaders before filling the silos.

Depends what you mean by "hand". Steel framed buildings and shipyards
use hand-carryable drills with magnetic clamp bases. They're just
about liftable, but have to be clamped down in use. They have a rack
action quill, like a bench drill. I've seen holes a few inches in
diameter being drilled by these things.

Bosch also make a 1500W _cordless_ demolition hammer that can drill
16mm in concrete.

My biggest drill is an ex-army road breaker that drills concrete up to
a couple of inches diameter. Only problem is that it needs 400V 400Hz
3 phase AC to operate !  I have to drive it from a converted bus
alternator and a petrol gen set.

As far as standard electric hand drills, Milwaukee makes a big drill that is
good for 1 1/4" in steel.  I've got one.  It has a #3 morse taper socket.
I use it for reaming out holes.  I would hate to get a 1 1/4" twist drill stuck
with this drill, it might spin me around!

Larger drills of this type are made, but bigger ones are usually air powered.

Magnetic base drills are a whole different story.

My Dad has a 1940's Chicago Pneumatic electric with a 3/4" Jacobs chuck
and an Ingersoll Rand air drill with a No. 5 (that's not a typo) Morse
taper socket. The latter monster requires two guys just to pick it up. As
I recall it needs something like 100 cfm at 100 psi. Don't ask me why he
bought it. Both drills have jack screws built into the top.

I am currently in need of a 100-120mm Rolling mill in good condition. 
Gear reduction is not important. Side rollers would be nice but not 
important. I do need a combination type(wire/flat) mill.If you hae 
anything close that is usable for gold or silver please E-mail me at
