ABSTRACT:
A drill press is magnetically mounted on a steel plate which is clamped to a manhole cover by three L-shaped clamps. The L-shaped clamps are mounted in slots defined by brackets located on the periphery of the steel plate. Enlargements are provided on the L-shaped clamps to keep the L-shaped clamps from falling out of the slots.
