thanks everyone. I wouldn't mind drilling - the problem is when I
drill, i'm going through a spade bit like every 2 or 3 studs. it's
getting expensive.

First off, if this is "getting expensive", that's your own fault. Spade bits
can be *easily* resharpened in seconds on a grinder, or in a minute or two
with a file. There's no need to throw them away just because they're dull.

Second, if you're dulling them that fast -- your drill is set in reverse. Flip
the switch so it spins the other way, and it'll work a LOT better.
