Abstract

The tool casing comprises an upper portion (104) affording two compartments (103, 153) whose internal walls provide electrical contacts (108, 108', 158, 158'). Each compartment can receive a double-ended cassette (102, 152) having projecting electrical contacts (120, 120', 170, 170', 170'') which will cooperate with those in the respective compartment. The cassette can be inserted in the appropriate compartment so as to present for use at the forward end of the tool alternative function elements such as a screwdriver bit (or socket wrench (112)) and rotary chuck (113), in the case of the first cassette (102) which incorporates a drive motor (101) and any necessary change-speed gearing (110); and a soldering iron (151) and electric lamp (162), in the case of the second cassette (152). <IMAGE>
