Last night I bought a new 200 series Dremel to grind off a tack welded-on nut (15mm) and knew I'd have many other future uses for it. I also bought a package of metal grinding discs.
At first I'm not entirely sure I was using it correctly. I wasn't pushing it or putting any weight on it but I managed to set two of the discs out of balance. The third disc I used stayed in balance even though I cut over twice as much with it than I did with either of the previous discs, which is why I think I must have been doing something wrong with the first two. When I was taking off the disc, I noticed that as I turned the collar it was squeaking as I turned it unlike when was putting on the discs it was silent. I tightened the disc on again and put it on the low speed (15,000 rpm) and noticed it sounded somewhat different than when I had it on low before I had ground anything; no sound difference was noticeable at the higher speed (35,000 rpm) Also I noticed it was emitting an unpleasant smell that I had dissmissed as simply the smell of ground metal as I was grinding.
Is this sound difference / smell of any importance? It was about 20 degrees in my garage where I was working if that has any importance.
