  • Publication number: 20180333829
    Abstract: An accessory driver tool connectable to a power tool includes a main body and a sleeve. The main body includes a first end, a second end, a tool coupling mechanism at the first end, and a first fastener driving member disposed at the second end. The sleeve, disposed concentrically about the main body, includes a second fastener driving member disposed adjacent the second end of the main body. The sleeve is axially displaceable along the main body between a retracted position, in which the first fastener driving member is exposed to engage a first fastener, and an extended position, in which the second fastener driving member is exposed to engage a second fastener. The sleeve is rotatable relative to the main body while in the extended position.

  • Patent number: 9731358
    Abstract: A drill bit includes a shank, a transition portion, and a body portion defining a plurality of axially stacked, progressively sized steps. The steps include a first step and a terminal step coupled to the transition portion. The first step defines two tip flutes each disposed at a tip flute angle. The body portion defines two body flutes each extending from the first step to the transition portion and disposed at a body flute angle different from the tip flute angle. The drill bit includes a bit tip disposed at the distal end of the body portion and having a chisel edge, a first chisel surface on one side of the chisel edge, and a second chisel surface on an opposite side of the chisel edge. The first chisel surface defines a first relief angle. The second chisel surface defines a second relief angle different from the first relief angle.
