Abstract
The invention is a revolving pilot tool. The inventor's revolving pilot has a cylindrical shank which is attached to the tool usually in the center of the bottom of the tool. This shank has a threaded opening in its center. Over the shank is placed a cylindrical bearing. Over this bearing is placed another cylindrical piece that forms the outer surface of the pilot. To hold the bearing and the cylindrical piece upon the shank a screw and o-ring is usually used. This pilot is usually attached to the bottom of the tool to align the tool to an already drilled opening. However, it could be attached above a drill to align the tool to an opening being drilled. The pilot can also align the tool during line boring.
Claims19
A revolving pilot for a tool comprising:
- a. a cylindrical piece with an inner and outer diameter made out of material that is wear resistant and said outer diameter is the outer diameter of the pilot and said cylindrical piece has a top and bottom inner diameter and said cylindrical piece has a lead edge;
- and
- b. a bearing piece with a top and bottom and said bearing piece is cylindrical and made out of material that is wear resistant and said bearing piece fits within said cylindrical piece said bearing piece outer diameter is approximately the same as the inner diameter of the cylindrical piece and said bearing piece is shouldered outward;
- and,
- c. a means for attaching the cylindrical piece and the bearing piece to the tool.

- and
- b. a bearing piece with a top and bottom that is cylindrical and made out of material that is wear resistant and that fits within said cylindrical piece said bearing piece outer diameter is approximately the same as the top or bottom inner diameter of the cylindrical piece;
- and,
- c. a means for attaching the cylindrical piece and the bearing piece to the tool;
- and,
- d. the cylindrical piece bottom inner diameter is larger than the outer diameter of the bearing piece thus forming a cavity between the bearing and the cylindrical piece.
