Use separate felt wheels for each polish grit to achieve a professional finish.
Match wheel size and motor horsepower for optimal performance: 6" wheels at 3600 RPM for 1/2 hp or under, 8" at 1800 RPM for 1/2 hp or over, and 10" at 1800 RPM for 3/4 hp or over.
Soft felt wheels are recommended for most work, while medium or hard wheels should be used for 555™ Polish.
