Hi,
As part of my ongoing ensuite project, I need to drill a hole through my wall for the new 110mm soil branch and shower/sink waste.
I guess I need some kind of core drill but not sure of the type or the size I should use. Ideally something not too expensive as I will only need it the once.
The wall is 2 rows of concrete blocks, rendered on the outside.
Do I buy one that is 110mm or should I get a bigger one?
I was thinking I could drill a pilot hole from the inside out to get the position right, then drill the main hole outside in to keep the mess outside?
