SWMBO wants me to build a small deck. Of course, every new project requires a
new tool, right? And my trusty Bosch cordless drill is showing its age a bit,
or to be more precise, the batteries are showing their age -- building a deck,
I'll definitely drain the batteries in much less time than it takes to
recharge them.

So I'm looking at other options, including compressed air drills (e.g. saw one
at the Borg this evening for $45 or so). But I got to wondering... almost
every cordless drill has a multi-position clutch to prevent overtightening, or
sinking screws too deep. Does anybody make an air drill with such a clutch?
