My cordless dremel 7.2v multipro has 2 speeds. Suddenly only the low speed works and not the high. Could it be a connection issue since the switch actually moves the connectors to different points in the battery. Last week I drilled 2 holes onto steel until I got a drill, hope that didnt messup the dremel!

Also,
What would be the BEST (and not too expensive) dremel tool /setup for a RC hobby workshop?!

And a silly question, Can a drilling machine be used for sanding, grinding , cutting into wood/ metal etc or is the only thing that can go into the chuck is drill bit? I have a ryobi drill costed $30.

And, I have to shorten the width of a steel engine mount which is about 2mm thick . I need to remove about 2to3mm on the side. Do I sand it with the dremel or cut it? Whats most effective?


Thanks--747
