  • Publication number: 20130175769
    Abstract: A combination tool holder includes a holder body, at least one tool adapter and a bolt. The holder body defines therein a through hole including an enlarged-diameter segment, a reduced-diameter segment and a tapered segment. A stepped surface is formed between the enlarged-diameter segment and the reduced-diameter segment. The tool adapter defines therein a channel and has a combining end. The combining end has a conical surface configured to be received in the tapered segment. The bolt includes a screw and a nut. The nut is configured to abut against the stepped surface while the screw extends into the tapered segment to engage with the combining end. By screwing the bolt, the conical surface is driven to press against the tapered segment, making the through hole and the channel coaxial.

  • Patent number: 7802948
    Abstract: The invention is a drill bit extender and method that enables holes to be formed or screws to be driven remote from a drill motor. It includes a drill adapter for attaching to a drill bit, hole saw, or spade bit, for example. The drill adapter accepts a threaded rod, such as a segment of rod that is threaded along its entire length, where the length of the rod determines the distance that a hole can be drilled remote from a drill motor. The rod is readily attachable and replaceable to enable an operator flexibility in drilling at various locations remote to a drill motor. The rod is attached to a drill motor by a drill motor adapter, which securely retains the rod in the drill motor adapter, enabling the drill motor to drive the remotely located drill bit efficiently.
