If you need to drill that many holes, get the best bit you can afford and a
sharpener and keep the bit sharp. Drill about 15 to 20 holes and resharpen.
Drill Doctor is ok and reasonably priced.

Subject: [TowerTalk] Drill bits
Hi all,
I don't know why this is so hard. I'm trying to drill out some hole on
some 3/8" steel plates that I'm going to have galvanized. 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?
73,
Guy, N7ZG
