Realy good quality drill bits
I made my mounting rack for my solar panels out of used steal pipe, and I had to drill quite a few holes for mounting these panels. The piping was quite hard and I bought five drill bits, so as to make sure I wouldn't run out. To my surprise the drill bits held up really well and I was able to drill all the holes with just one bit. I did pre-drill the holes with a center drill, but that was all I used, and of course some lubricant. I never thought that I could drill these many holes without wearing out the drill bit. Quite amazing.
