#Question for #masonery #drill experts .. is there any ( professional ? ) drill/drill-bits combination that would drill through massive stone/quartz/cement "like it'd be butter" ? Once I had something like that in my hands but I don't know where they got it. I am TRYING to do some works on a 200 and more years old house made mainly of super hard stones. "Normal means" seems to struggle this is what I had to do 16 years ago .. https://www.youtube.com/watch?v=jgj6FmWusBc today 3 hours to put 2 lights on a wall.
