Abstract
A drill/driver (2) includes first (32) and second (52) drive shaft. The two drive shafts (32, 52) are independently rotatable about respective axes (A-A, B-B) thereby to selectably choose the radial and axial position of the final output drive of the drill/driver.A shaft lock (56) is provided to enable the user to selectively lock either or both of the shafts (32, 52) against rotation about their respective axes.
