My 12 volt cordless Drill Master from HF should do 3 inch
screws. The charging system is not regulated, I have to
allow it no more than 3 hours on the charger. That said,
it's several years old, and keeps on running. My sense, with
the cordless from HF, they are all reasonable, but not
The last ones I got from HD were some years ago, can't
remember the voltage. But at $20 per drill, it was cheaper
than the $28 battery replacement pack for my Skil drills. HD
has Ryobi, Dewalt, and some pretty nice cordless. So, if
you're looking for one to use on the job, I'd go there.
My work horse cordless drill for the job is Makita 14.4
volt. I've worn out a battery or two. Found a battery at a
clearance sale, and bought it. Someday I'll send the worn
out batteries to Primecell.
