Using a bench drill ?
if you are not using a bench drill where the speed is SLOW you can eat and eat
the bits
use any lubrican you have , careful with WD-40 if is very hot can ignite ,
transmission oil is fine or Motor oil just a droops,
but the most important is to have a powerful DRILL at low speed and you can
make a lot .
using a good brand Drill bit is always the best way, cheap bits are for
one small job use or break very easy. use safety goggles
learn how to sharpen those bits is no difficult .
just remember that the hole will be a little smaller after be galvanized

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
