That depends on the operator, and the tool.  I have a mandrel that I can
put on my wood lathe to hold buffing wheels.  Being a lathe, it's variable
speed, so I can set it to go real slow.

I usually have it on the second slowest for wire-wheel work.  Any faster
and it starts to spit wires out (which are a pain- especially in wool)

If you have a converted bench grinder, then it will be moving real fast-
so to avoid heat buildup, don't use a lot of pressure.  It will take
longer, yes... but it'll do a nicer job!

Some things require patience.

I've also found that you can produce a fairly nice finish with a hand-held
(ie. non-powered) wire brush.  No heat buildup- but a lot of bicep
buildup!  I have a stainless-steel bristled one, with two hand-holds; it's
nice because I can leave it out in the rain :-)
