  • Patent number: 10953534
    Abstract: Handheld power tools are adapted for magnetic stabilization based on the incorporation of one or more permanent magnets in a base thereof. One or more permanent magnets may be incorporated into the base of a handheld power tool (or a detachable rechargeable battery base) such that when the base is contacted with an inclined steel roof panel, a magnetic force is applied that is sufficient to secure the handheld power tool in an upright and non-operational configuration. The distal region of the base may include a spacer formed from a compliant material to provide a spatial offset between the one or more permanent magnets and a surface with which the base is contacted. In some example embodiments, a rechargeable battery pack may include one or more permanent magnets that are capable of supporting the weight of an associated charger when the battery pack is contacted with a vertical steel surface.
