  • Patent number: 7264427
    Abstract: A drill bit apparatus having a central shaft and an annular collar mounted thereon. The central shaft is coaxially positioned within the annular collar. The central shaft has a bit end and a cutting tool end. The annular collar is spaced between the bit and cutting tool end. The bit is configured for releasable securement in a chuck of a drill or drill press. The cutting tool end is configured to securably receive a cutting tool therein. The cutting tool lower portion has a central bore cutter essentially coaxial with the shaft.

  • Patent number: 6374708
    Abstract: A tool is provided for installing and removing winterizing plugs located in drains, pools, boats, and other systems for providing protection from moisture during the winter season. Such plugs have threaded stems, and are typically secured by wingnuts. These plugs are then removed during warmer weather. In operation, the set screw is loosened to permit removal of the t-bar from the barrel. The t-bar is then inserted into a second transverse bore to serve as a handle for applying torque to selectively tighten and loosen the wingnut and to facilitate pulling the wingnut. The slotted end of the barrel is then slipped over the wingnut. Then, the wingnut can be easily tightened. This technique is also used when removing the plugs. The end of the tool is applied to a threaded portion of a winterizing plug above a wingnut for removal of the plug. The threaded portion of the winterizing plug extends well above the wingnut. The threaded portion of the passage engages the threaded portion of the winterizing plug.
