Run an extension cord!!!
I have two, and use them equally
I have the cordless Minimite 7300 (6,500/13,000RPM) and the corded 200 Series (15,000/35,000 RPM)
I find the slower 6500 RPM very useful for the sanding attachments. Many of the sanding buffs, wire wheels and discs work better and last longer at a lower rpm.
Cutting and grinding, 6500rpm is nice, but takes too long, especially w a battery not lasting that long.
35000rpm makes quick work of most things.
the EZ Lock shaft bit and its accessories are great, as well as the flex shaft attachment.
