ABSTRACT:
The invention provides a tool particularly adapted for working metal. The tool comprises an electromagnetic coil, a pole adapted to be magnetized by the coil, and a work surface pivotable with respect to the pole and operative in use to apply bending force to a work piece held to the pole by magnetic force.
Keepers may be provided to be attracted to the pole to hold the work piece. A keeper may be fitted with a cutting blade or punch.
The work surface may be part of a body which, when moved from a rest position, causes the coil to be energized and which is urged by magnetic force back to that rest position to de-energize the coil.
The body is preferably connected to the pole by a hinge which does not project above a plane so as in no way to hinder metal bending.
A tool may magnetically clamp itself to a bench.
The tool may have an electrical circuit capable of producing DC for magnetic holding or AC so that the tool may be used as a demagnetizer.
