ABSTRACT:
A cordless electric tool in which a motor is mounted in a housing and to which housing a battery source is connected to operate the motor. The battery source is in the form of a battery pack that will be slide-fitted into the housing to be detachably connected thereto. The tool housing has a hollow portion or cavity which receives the battery pack. The motor has a pair of terminals which extend into the cavity to mate with co-acting battery terminals of the battery pack. Resilient means, preferrably an "O"-ring yieldably engages the motor terminals to increase the mechanical and electrical contact between the respective motor and battery terminals.
