Abstract
A portable cordless finishing sander is provided which has a housing, a sanding plate below the housing and a clamping arrangement for clamping a sheet of sandpaper to the sanding plate. The housing has a motor housing portion for storing an electric motor, an elongated handle portion extending above the motor housing portion for storing a battery, and a skirt portion extending below the motor housing portion. The housing is designed in relation to the handle portion and the skirt portion such that the weight of the handle portion encasing the battery is substantially equal to the weight of the skirt portion carrying the sanding plate in both vertical and longitudinal directions. The clamping arrangement includes a clamping member and an operating lever, which are normally stored within the skirt portion of the housing. A novel arrangement is provided for retaining the clamping member in its released position when the sandpaper is exchanged.
