Drill tool

摘要

A drill tool comprises a drive shaft (2) that is arranged to allow rotational movement to be transmitted from a drill to a drill bit holder (10) even when the opposite ends of the drive shaft are not axially aligned. The end of the drive shaft housing the drill bit holder (10) can be inserted into a guide member (14) that includes a planar element (18, 42) that is arranged to ensure that the drill bit is maintained at substantially 90° to the surface of a work piece being drilled even if the drill itself is not so aligned.
