MID55020CAUS, Mirka 5in DEROS 550CV 125mm, Orbit 3/16” (5.0mm), Vacuum-Ready, Random Orbital Sander

Mirka® DEROS 550CV direct electric random orbital sander has a 125 mm (5”) pad and a 5.0 mm oscillation. The main voltage is 120V. Mirka® DEROS 550CV is suitable for general sanding purposes on almost all kind of surfaces and particularly for smaller areas because of the 125 mm (5”) pad. Its performance is comparable to a conventional 500W electric machine and that ensures it maintains a constant speed even under heavy load. The unique symmetrical design makes it just as comfortable whether it’s being used in the left hand or the right hand and the longer body provides the option of a two-hand grip. Mirka DEROS 550CV is equipped with a backing pad, which has a central air inlet. This results in improved air flow and helps extract dust away from the centre of the tool even faster. Mirka DEROS 550CV is delivered in a high quality plastic case.
