The Mirka DEROS II Electric Sander features a refined design that puts greater control in the hands of the user. Updates include clearly visible LED speed indicators, a dedicated on/off switch, and lockable speed settings, which allows users to quickly and confidently dial in the right performance for the task at hand. A key addition is the new 7" model, designed specifically for sanding larger surfaces, enabling users to cover more area with fewer passes without sacrificing control or finish quality.
