I need to drill a couple of 155mm holes in a wall (Breeze/red brick)

As I only need to drill a few holes I'm thinking of buying a cheap
drill for the job (As it's cheaper than hiring it doesn't matter if it
gets knackered)

There are a couple of problems you can have drilling brick walls with
a core drill
a) using it on hammer action can knock the bricks out of the wall.

Yep, this is a problem with TCT drilling but not with a diamond core which
must be used without hammer.

I'm sure I remember hiring a TCT bit/Kango combo which did little more than
scribe a circle before I got tired holding it up, if I recall.

b) if the drill binds it will try and twist you.

Indeed, which is why people who have been there advocate getting a drill
with a safety clutch. The real cheapos don't seem to feature this, even
the Axminster, though at least their brochure cautions about this.
