Abstract
A drill guide assembly for a drilling tool having a chuck engaging a bit portion comprising a tip and a length extending from the chuck, the drill guide assembly comprising a first member, a second member and a trackable member. The first member is adapted to abut a workpiece surface and defines a central aperture therethrough adapted to receive the bit portion of the drilling tool. The second member is adapted to be axially displaced with respect to the first member and is axially biased therefrom, and defines a central aperture therethrough adapted to receive the bit portion of the drilling tool. The trackable member, fastened to the second member, comprises a detectable element adapted to be located and tracked in three dimensional space, thereby defining the position and movement of the second member and therefore that of the bit portion of the drilling tool.
