My angle grinder has a brushed motor, meaning that it can be slowed down
with an SCR-type speed control (e.g., HF's "Router speed control":
http://www.harborfreight.com/router-...rol-43060.html ). I know
that it won't have as much power when slowed down & that won't be a problem.

The question is: is it going to be harder to avoid burning it out? It
can be burned out at full speed, too, and I know how to avoid that. Is
it different at slow speed?

Thanks,
Bob
