I had to drill through a 6 inch thick flat concrete roof to install a 4 inch drain. I used your 4-1/4 inch hole (core) saw. It drilled quickly using a HD 1/2 inch Milwaukee right angle drill turning at about 500 rpm. I must have hit rebar or steel mesh several times -- when I did the drill jumped around. But I got through it faster than I thought I would. Project completed much faster than expected.
I would recommend these saws.
