Erm it's a cavity wall?!

And?


His angle grinder only cuts to 3" he says, so he can't cut from
the cavity sides of both leaves of the cavity
really thin ;-)

Ah. My angle grinder cuts through a standard brick. Thought that was why
it was the size it is. But even if not, a nice neat edge to the face as
deep as it will go followed by splitting should still give a decent job.
