I would like to make a hole in a single-leaf brick wall, so I can pass a
22mm copper pipe through. There is access to one side of the wall only.

Would using a 25mm SDS drill be a satisfactory and safe way of making
this hole? Would break-out on the far side be a problem? I have never
used an SDS drill as big as this (nothing bigger than 10mm previously),
so I am not sure what to expect.

Or should I be thinking of using something different from an SDS drill?




It will be fine - if break-out is a problem [cosmetically] go through with
a smaller bit first, then back (from the visible side) with the 25mm.

Thank you for the reassurance, it gives me confidence to have a go.
