That’s why for more extensive projects like sanding cabinets or refinishing furniture, corded sanders still have the edge. Cordless sanders have improved dramatically over the past few years–thanks to more powerful brushless motors and lithium-ion batteries that run longer and deliver more consistent sanding power. Most random orbital sanders run somewhere between 7,000 and 13,000 OPM. Most orbital sanders include a dust bag or canister that captures debris through holes in the sanding pad that line up with pre-drilled holes in sanding discs. Good orbital sanders, like the , are designed with balanced motors, rubber overmolds, and improved ergonomics to reduce fatigue.
