Abstract: A hand-held drilling tool has at least one but preferably two blade structures which project longitudinally from a transverse base member to terminate in a distal end that forms a cutting element. Each blade structure has a pair of blade sections that are joined together along the longitudinal axis and that extend radially therefrom to terminate in lateral edges. Where two blade structures are present, each forms a handle for rotatably operating the other blade structure; where only one blade structure is present, a flattened handle is provided. The blade structures can have different blade widths for drilling differently sized holes. The blade sections may be offset from one another, and wedge-shaped feet may be disposed on the cutting elements. One of the blade structures can have both a bit portion and a shank portion of different widths. A pilot tip may also be provided on the distal ends of the blade structures. The drilling tool is configured for unitary molding from a plastic material.

Abstract: An installation clip has a base member that fastens to first electrical cable already secured to a structural member in order to mount one or more second electrical cables indirectly to the structural member. A clip structure is disposed on the base member and has a pair of resilient retaining arms that extend outwardly from the base member in opposed, spaced-apart relation to define a clip channel into which the second electrical cable(s) can be placed. Shoulders may be formed on the distal ends of the retaining arms to define an inlet into the clip channel, and lips may be disposed on the shoulders to form a V-shaped opening into the clip channel. The retaining arms may also have opposed central flanges that project into the clip channel parallel to the base member to form upper and lower regions, and a spacer may also be disposed on the base member to separate the lower region into a pair of subregions. These regions are each sized to receive a second electrical cable.
