Check the listing for details. Rotary Tool Machine R.P.M. 8000-18000 9-18VDC. Condition: Used. Listed at 12.00 USD. The speed of this tool is controlled by varying the input voltage. It comes with a 12V power supply that runs it at a single speed. This was in my dad's estate, so I don't have any more information about it. I turned it on, it seems to run fine.
