Polishers, also known as rotary polishers can both sand and polish surfaces to a high finish. These 180mm rotary polishers accept pads up to 180mm in size. These tools are called rotary polishers because the pad is spun, or rotated in a circular motion. This makes the tool quite powerful, but care is needed when using, as these tools are capable of damaging surfaces due to this consistent motion and built-in inherent power.
