Chuck key tool

A chuck key tool comprising, in combination:

• a unitary tool consisting essentially of a solid metal central hub with at least three projecting spokes, each spoke defining an axis extending radially outward from the hub, said axes being coplanar, each one of said spokes terminating in a separate distinctly sized chuck key, each key having teeth and a guide pin, each of said teeth extending radially from the associated spoke axis outwardly to a radial extent from the projecting spoke, each said guide pin extending longitudinally outwardly from each spoke along the associated spoke axis, and said hub positioned at the intersection of the axes and defining a solid center for the tool, said hub center including an integrally cast magnet pocket defined by a cylinder with a cylindrical counterbore transverse to the spoke axes, said cylinder extending outwardly and having an axis centered on the intersection of the axes of said spokes, from the hub center, said spokes, hub and teeth comprising a unitary metal casting having a gate located on a spoke intermediate the teeth and the hub;
• and
• a separate round, disc shaped magnet mounted in the pocket, said pocket and magnet defining a face in a plane parallel to the plane defined by the axes and spaced from the intersection of the spoke axes by a distance greater than the maximum radial extent of said teeth and providing a flat planar tool surface which supports the tool on a flat surface with the teeth of the tool spaced from the said flat surface.
