I bought a 13/32" drill bit and it worked great for about 10 holes or so. The problem is that I have about 140 more to go. Any recommendations on a good quality drill bit?

Are you using a cutting lubricant?
Are you doing it in one shot, or starting with a small drill size and
working up?
What speed are you running the drill at? (It should be fairly slow, RPM
wise..)
Are you using a drill press or hand drill?
