The Mirka® DEROS 5650CV direct electric random orbital sander has 5.0 mm orbit and both a 125 mm and a 150 mm pad. The high efficiency brushless motor has plenty of power to get the job done quickly; with a performance comparable to a conventional 500W electric machine, it maintains constant speed even under heavy load. Mirka® DEROS has a soft start function, a built in electronic motor brake and a smooth, easy to operate lever to control motor speed.
