Can I drill a 1 3/4” hole through a manhole cover
We have a manhole in our back yard that goes to a rain sewer. I want to back flush the in ground pool ont the sewer. I can lift the cover every time but what I really want is to have a hole with 1 1/4” sch40 pvc through it so I don’t have to mess with it.
I can drill it fairly easily with a 1/4” twist drill. I got out my Milwaukee hole saw and was a littl surprised that it made some progress before the pilot drill snapped.
I can rent one of those magnetic drill presses for $55/day but the rental place has no bits.
suggestions?
