Abstract

A drill bit setting device (40) includes a holder (42) for holding in use a drill bit (10) substantially in alignment along a longitudinal axis (76) of the bit (10). The drill bit setting device (40) includes first limit means (70) for limiting movement of the bit (10) along the axis (76) and second limit means (72) for limiting rotational movement of the bit (10) around the axis (76). The first and second limit means (70), (72) define a pre determined set position relative to the holder (42).
