Drilling Flagstone
I need to drill about fifty 3/4" holes (~2"deep) in my flagstone paver deck. These are the anchor points for my pool cover, they all need to be re-drilled because I had my deck surface redone.
This material is hard, extremely hard. Normal carbide bits barely touch this stuff. Even a 1/4" hole is slow going with my HF 'regular' 1/2" hammer drill. It cuts easily with my diamond saw, but I need to drill, not cut.
I need some way to drill faster, and ideally a bit that can drill all fifty holes. I've looked at diamond coring bits, they get good reviews, but they have a short life. I don't want to burn through twenty drill bits at $30 each.
Soooo, bigger/better drill (e.g. Hilti) and Milwaukee SDS drill bits?
Any other ideas/suggestions?
