You guys werent kidding. I had plenty of hp today. I have never been big on maintanence though. What do you guys do to kepp them runnng as good as when you get them. Also what i the scoop on the XXX brushes. I know they last much longer but have heard they are a little down on power and they are hard on the com. Also i have a lathe but i think i managed to chip the diamond bit. Does anyone use carbide anymore, i am having a hard time finding one.
