A portable electrical tool includes a tip tool; a cylindrical housing accommodating a motor including a chuck attachably and detachably holding the tip tool at tip end of a rotation shaft; a base including a surface plate which slides on an upper surface of work material, and which allows the tip tool to protrude from the surface plate downwardly, a cylindrical portion including a cutout portion, and a lever having a cam surface, and rotatable to a fixed position and a release position. When the lever is in the fixed position, a gap at the cutout portion is narrowed to stop movement of the cylindrical housing. When the lever is in the release position, the cylindrical housing is movable by weight in the cylindrical portion. The tool includes a stopper to stop a rotation of the lever between the fixed position and the release position.
