Guy, did you use some oil to reduce friction/heating? Did you slow the  
drill speed way down to reduce heating?

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
