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.
Claims16
A drill adapter to enable remote drilling operation, comprising:
- a cylindrical stock defining an internal bore adapted to retain a drill bit shaft;
- a hollow adapter shaft adapted to engage one end of a threaded rod;
- said threaded rod selected from a plurality of desired length rods to enable the remote drilling operation;
- wherein said threaded rod is fixedly retained in said hollow adapter shaft by securing nuts;
- and
- wherein said cylindrical stock includes two opposing wrench flats to facilitate gripping by wrench.
A drill extension system to enable remote drilling operation, comprising:
- a drill adapter including a stock defining an internal bore to retain a drill bit;
- a hollow adapter shaft adapted to threadably engage a threaded rod;
- said threaded rod selected from a plurality of desired length rods to enable the remote drilling operation;
- a drill motor adapter comprising a drill motor adapter shaft that engages a drill motor chuck and a boss that engages said threaded rod;
- said threaded rod is fixedly retained in said hollow adapter shaft by securing nuts;
- and
- wherein said drill motor adapter boss has an internally threaded bore to engage said threaded rod.
A method of drilling a hole remotely, comprising the steps of:
- selecting a drill adapter;
- selecting a drill motor adapter;
- selecting a threaded rod having a length suitable to remotely drilling a hole and securing nuts that engage said threaded rod;
- threadably engaging said threaded rod comprising securing nuts to said drill adapter and to said drill motor adapter;
- attaching said drill adapter to a drill bit by means of a set screw;
- and
- tightening said securing nuts on said threaded rod to removably retain said drill adapter and said drill motor adapter to said threaded rod;
- and
- positioning the drill bit and drilling a hole with the attached drill bit.
