Strong Finisher. Porter-Cable's 390K 5-inch random orbit sander has a powerful variable-speed brushless motor and delivers consistently fine sanding results. In fact, it won top honors in a recent tool test performed by JLC's sister magazine Tools of the Trade. The low-profile design is wider than most, with a low center of gravity. Features include a motor brake, electronic motor controls for soft start and constant speed under load, and an exhaust port that fits a vacuum hose or the included dust canister. The tool uses standard hook-and-loop disks and comes in a plastic case. It costs $130. Porter-Cable, 888/848-5175.
