out with the old.....this is the same as the one I have except mine is red instead of blue and it sucks because the contacts always get dirty and the battery is not powerful enough.

Time to go burn and shatter some cutoff wheels

 

yummm perty

You know about this, go and take some r/c stock motor break in oil and put it on the brushes. Oh man, put my dremel next to my friends, definitely a difference. I guess I can't leave anything alone.
