Abstract

A level that is attached to the drill bit. It is on a bar that allows the level to be offset from the drill bit so that it is visible by the operator. The bar has a bearing in it that allows the bit to spin freely while holding the level in a set position. The level has a ball that centers in a ring when it is level and plumb. To use the device, after it is installed in a drill, the operator adjusts the position of the drill until the ball is in the center of the ring. Then, the drill bit is plumb and the hold will be true. The operator merely has to watch the level and adjust the drill as needed to maintain plumb to ensure a true hole.
