you do not need carbide for aynthing but aluminum, just get the normal diegrinder stone bits, they work great.

yes, you do use air die grinders, you can get an electric diegrinder that will have more power, but is not made to be run for long periods of time like air tools can be. Don't use a dremil, there are stil so many people that talk about porting with one of those. Horrible idea.

I have electric grinder and it works very well. Why is it that pneumatic grinder is meant for longer period than electric? Pneumatic grinder requires oiling periodically, electric don't. Electric is more portable. Can you explain? (Didn't mean to hihack)

just like any electronic tool, they aren't ment for long preiods of use, because they heat up too fast. I have burnt several electric grinders up that way, and you can run a pneumatic tools all day long because they are cooled by the air.
