With the flip of the conveniently located handle switch, get professional high-gloss buffing results at 300 rpm. You'll double your productivity potential with two-speed floor machines. This floor machine is the best of both worlds. At one speed it is a floor grinder and at the second gear it is a high speed buffer. The Floor Grinder/Buffer is a great two for one machine
