Talking of which, has anyone tried those new diamond cutting blades for
angle grinders that claim they can cut metal as well as masonry?

I wondered what the cut quality and speed is like in metal, and also how
well the blades stand up.

Yes. It transforms a cheap angle grinder into a useful tool.
The blades don't last for ever but they do last for a very long time. More
usefully they don't wear down smaller like abrasive cut-off discs, which
results in making the disc too small (in diameter) to work. Also they make
a magnitude less sparks and much less debris.

I also use a power hacksaw (Bosch £100 job) which takes a variety of
blades [1] including ones intended to cut steel. The trick is to keep the
tool firmly against the pipe no matter what, and the blade lubricated.
