Hammer Drill for Granite

What is the easiest/quickest way to drill granite? I have a commercial project where I need to drill 200 1/4'' holes through 3/4'' thick granite slabs. I tried carbide bits and it took way, way to long and way too much effort for what it's worth. I ended up punching out the last .5'' inch or so with a hammer and nail set which worked great but is there a faster, easier way to get through this stuff like say a hammer drill?

Thanks

Josh

That was my next thought, I'll give it a try

How long should it take to drill these about 3/8'' deep to knock them out, roughly per hole? Sorry for all the questions, I'm starting Monday and need to knock this as well as several other big projects out by the end of the month and I've hardly had any experience with drilling stone.

How many bits should I expect to go through?

Thanks again

Industrial diamond

Industrial diamond should take about 30 seconds to drill thru 3/8" thick material at best.
