Unnecessarily nasty when, in all fairness, the thread _is_ about
machining ferrite, and the heat he was referring to (which I think
most of the rest of us picked up on) could only have been caused by
the grinding operation.

Pretty easy to grind with normal emery grit products too. Even those
'sut-off-saw' discs will work.

DAGS for "ferrite machining".

it's a ceramic;grinding can introduce stress fractures(cracks).
