Yup - that I understand.

Did this:

two fixing holes

imply using a single-hole cutter twice in order to make a two-gang hole?

This is how the double back box is done:

it looked like he had already made most of the hole when that video started

still looks like a pretty fierce tool, bet you need a big drill to back it up.

Here's one of another version starting from scratch:

The first one needs an SDS Max drill - don't think they make small ones.

The second is SDS +, and they say "Drill must have an actual net weight of 4kgs or more & 4 to 5.5 Joules of power. "

For both tools they say "Designed for use in breeze block/masonry materials.", but as ever the demo videos show lightweight blocks - I wonder how well they would fare in hard brick....
