Abstract
A drill adapter is fashioned to enable right-angle drilling, incorporating an input drive, an input bearing, an output bearing, and an output drive. The input drive is capable of receiving a hand-held driving tool and the output drive is capable of engaging a fastener. The input bearing, which is driven by the input drive, is operably attached to the output bearing, which drives the output drive. The adapter incorporates a housing to protect the bearings and also has a handle to enable an operator to grasp.

An offset drill adapter, comprising:
- a main body having a middle portion, a proximal end, and a distal end;
- an input shaft disposed on the proximal end of the main body;
- an output shaft disposed on the distal end of the main body;
- a plurality of bearing support fasteners disposed around the input shaft, the bearing support fasteners include a first roller and a first screw;
- a plurality of roller support fasteners disposed on the middle portion of the main body;
- a handle support shaft disposed near the proximal end of the main body, the handle support shaft is adjustable along a handle support location area;
- a light switch disposed on the main body;
- and a pair of batteries wired in parallel and then a series connection is made to the light switch and a light-emitting diode to provide activation to the light switch;
- wherein the output shaft includes a quick-release chuck disposed on the distal end of the main body;
- wherein the quick-release chuck is surrounded by a first set of ball bearings;
- wherein an outer portion of the first set of ball bearings are bordered with a first metal ring welded to a first sprocket that drives a chain which connects to a second sprocket at the distal end of the main body;
- wherein the first sprocket is connected to a second metal ring with the second metal ring surrounding a second set of ball bearings;
- and
- wherein a set of 2 metal wear plates surrounding a bearing raceway on each side of the second sprocket for a total of 4 wear plates, 2 bearing raceways, the first set of ball bearings, and the second set of ball bearings.
