A power tool includes a motor assembly, a base assembly, and a clamp assembly coupled to the motor assembly or the base assembly to selectively provide a retention force to the other to removably couple the motor assembly and the base assembly. The clamp assembly includes a handle member, a fulcrum member, and a biasing lever member. The lever member includes a first portion and a second portion disposed on opposite sides of the fulcrum member. The handle member is coupled to the first portion, and the handle member is movable between an open and closed position. The handle member rotates the first and second portions of the biasing lever member about the fulcrum member when moving from the open to the closed position, causing the second portion of the lever member to provide the retention force.
