Is that what its called? can I just use one of those electric ones that yopu plug to the wall using a smaller disk?? or should i just buy a dremel tool set?? where do they sell e and for how much do they run for? I already have one of the big ones that you plug to the wall, I use that for cutting fiberglass, metal and all kinds of stuff...anyone?

you can get them at just about any hardware store like home depot or whatever the american equivalent to canadian tire would be. they usually are around 100-150 dollars.
the thing your describing would most likely work but if its large your limited when it gets into those tight areas you may need to use it on.
