got too move a waste pipe, rather than knock bricks out can you get a drill/boring bit too do the job ? Anyone got one, used one ?
Answers on a................
summat like this maybe but a little more suttle.
you allegedly need a diamond tipped core borer. I used to use them at work, nowadays i just drill loads of holes in a circle and use and SDS drill on
chisel mode to finish it off. Once mortared, you wouldnt really know. Plus, with ye olde 45mm hole borer, the widest part of the elbow outside doesnt
fit into the wall, resulting in a pipe a few inches off said wall.

What you need is a TCT core drill, places like Screwfix sell them and they go through house bricks without any problem. You can hire them if you only
have one hole to do. Make sure you check what size waste pipe you have first.

Yes you can get them..
Builder put a 6 inch diameter hole through my cavity wall last year to fit an air vent for a stove.
The bit looked just like a normal circular hole bit but very deep!!! left me a nice core of two bricks and cavity insulation between them.
No idea where to get one ..sorry
Most hire shops do them diamond tipped and normally charge you by the milimetre you use, or thats what they did for me when I hired one.
