The first random orbital electric sander using advanced brushless DC motor technology, without the need for an external power transformer. This vacuum-ready sander features a low profile of just 4 inches making it easier to sand in tight spaces and in small areas such as corners and tight contours. Its powerful brushless DC motor allows users to adjust speeds from 4,000-10,000 RPM, providing a high power-to-weight ratio. The ergonomic design has been a priority to ensure that the light tool can comfortably be used for long periods without fatigue.
