Would a 10 amp 1/2 Drill motor be powerfull enough to drill holes into 6x6
pressure treated beams? I have several that I need to drill holes through
and I know my 3/8 drill would be toast after one or two...
You don't say what size holes or how many.
Your 3/8 drill will probably do just fine unless it's a really
elcheapo. Buy 2 new spade bits of the size you want to drill - 2
in case you dull one if you are drilling quite a few. If you can
get one of the new Irwin speedbor max bits, they're awesome, but
Keep the whole world singing . . . .
Your drill should be fine. I have a selection of drills from the
smallest to the Hole Hawg. In my experience you will get fair warning
when you are doing too much with a drill. First you will smell it, a
burning smell. If you keep going it will get quite hot and you will
see smoke from the drill. Don't know what happens after that since I
always go up to a larger drill when this happens.
If you are using a spade bit, it is harder to do but with a ship
auger we use a drill motor like that to drill 2.5 CCA 12" dock posts.
With the spade bit, just take your time and clear the chips often. It
How many holes? How big? How fast? How hot is it in your area? Do
you know how to lightly press a drill into the work, lightly
enough that the motor doesn't stall? What's the speed rating of
your drill? Is it two speed?

You can\'t shout down a troll.
I've used a 1/2" drill to put that many holes in concrete with no problem.
This should be no sweat at all. Good that you are using an auger bit as
most all of the spade bits are really crappy and will take longer..
NO problem for anything but the absolute cheapest crap drills. Did that
with my cheap garbage 18v cordless -- no problem. Used an 18" twist
bit. The auger bit fed in too fast and stalled the drill. Also stalled
my makita 3/8" corded VSR. Twist bit was fine.
Like the other guy said, you'll get plenty of warning for overload if
you pay attention to the drill.
Just do it!

Milwaukee make 'Selfeed' bits in all sizes that are a delight to use.
I've used the 1" size with a 3/8" (Milwaukee, of course) drill with no
problems. These bits are usually found at industrial supply houses and
electrical and plumbing distributors that cater to tradesmen. Might
be at some box stores, but haven't checked. Amazon might be a source,
