Good from Robert advice here.

I prefer using lots of water soluable coolant to oil, just because I hate
the oil mess. Oil probably is better for the cutting edges though. I'll add
that a hole saw tends to give a rough edge and be oversized. If you need a
good accurate hole with nice finish, look at rotabroach.

Thanks for the advice. The holes are for dials and switches, so they
don't need to be extremely precise - it sounds like a hole saw would do
the job. But for maximum flexibility I might be better looking for a
magnetic drill with, say, a 50 mm broach capacity. The selection on eBay
is pretty poor, and I'm always reluctant to buy more expensive items on
eBay anyway. Sadly eBay won't provide you with a member's address
anymore, even when you've conducted a transaction with them in the past,
and I think that shelters bad sellers. Keep on looking I guess...
