What I learned about drilling concrete

Me and dad chiseled a hole through the basement wall for a chimney. Had to be 7 or 8 inch diameter. That was in the late 70’s.

I did the same on an 8" thick wall when I built a new house in '75... the guy that poured the walls put a plug in the wall for the sewer pipe...6' too low!

Wound up getting concrete bits in my eye and a serious burn from the same.

No rental outfits back then in the woods of the UP.
