job. i have an sds drill and was thinking of chain drilling the
circumference and the chiselling out the centre. if i hire a drill bit
what type am i after?

You get yourself a big drill pistol and a bit called a core cutter that is
the right size for the job. The core cutter should allow you a bit of
clearance around the pipe, so get one at 120mm, or close to, so that you
don't have to force the pipe into the hole.

Remember also that the wall could be a cavity construction so you might
also need an extention for the core cutter bit. Ask in the hire shop for
advice on this.
