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?
