INDUSTRIAL BUFFERS

 
Offered in a wide range of horsepower options, the U.S. Models 501 and 503 are ideally suited to a variety of buffing, polishing and wire wheel finishing applications. The tapered spindle housing design permits access to internal surfaces such as musical instruments and other highly finished products.

The extra wide wheel spacing on the Model 503 provides additional operator maneuverability. The four bearing housing construction rigidly supports the extra length spindle for extended life.

Select the appropriate size and horsepower to suit your individual requirements.
