Abstract
A driving tool for an elongated fastener of ferro-magnetic material, including an elongated hollow tubular body reciprocably receiving a driving rod having an impact end and a drive end. The drive end is characterized by an internal cavity receiving an Indalloy permanent magnet, the open end of the cavity being closed by a magnetic head, or pole piece, in such a manner that the axial impact forces imparted to the drive rod are transmitted substantially entirely to the magnetic head and not through the magnet. The Indalloy magnet is utilized within the drive end of the drive rod so that its magnetism will be retained, even if fragmented.
