In the past I've used the angle grinder to chase out electrical back

You can buy box sinking tools for use with hammer drills that cut the
hole exactly to the right shape for a single or a double gang wall
box.

Seen these and do wonder how well they work.


Not much use IMHO.

What I suspected. ;-)


It really does depend on the brick.

If it is red brick you get red brick dust and are left with nothing to
fasten the back box to, if is black brick you are left with black brick
dust and nothing to fasten the the back box to.

Other coloured bricks are available.
