Milwaukee Tool's M18 Fuel 15mm and 21mm random orbital polishers have been introduced for polishing and heavy-correction applications. As the first true corded replacement, they deliver more power and control than other cordless polishers on the market, while maintaining the superior ergonomics that users expect. The professional detailer spends an average of six to eight hours a day with a polisher in their hands. These polishers were designed with ideal balance and grip ergonomics to deliver all-day comfort and more control.
