Good suggestion. You can also sandwich two of the non-heavy-duty cutting discs together to make a stronger, fatter cutting tool. They don't break as easily that way.

I used my Dremel (actually the black & decker version) to shorten my cowhorn bars and modify a brake lever so it would fit in the end of the bar. Also, the polishing tool is good for removing black paint and Nashbar logos from aluminum components.

And, that cone shaped grinder tool for removing lawyer tabs from forks.

A dremel is a necessity when fitting new, high security locks to old house doors. Metal bits always need to be trimmed or shaved.
