I bought a Habor Freight-type 4" grinder before the prices started dropping for
about $35. (Now available for $20). It makes a lot more sense to me to run
this little electric motor instead of churning the 5HP compressor. To me, it
makes more difference on the task of the tool. If, like me, you're going to
grind down edges prior to welding, or dressing up weld beads, the inexpensive
electric grinder is ideal. It seems to have more torque than I can generate
from small air tools as well. There are both pros and cons to that issue, as
illustrated in some other responses to you, but with a modest amount of safety
awareness, I don't expect you will have a problem.
