Abstract
The device has a fixed rod 15 aligned with the working axis of the tool, e.g. a pistol drill. The rod 15 is in spring biassed, telescopic sliding engagement with a tube 16 fixed to an indicator head 17. The head 17 includes a universal-type pivotal coupling and bears indicia to indicate when the axis of the rod 15 is perpendicular to a work surface against which the head 17 bears. The rod 15 carries a depth gauge scale 19, and an adjustable stop 20 determines the maximum depth of penetration of the drill bit into the workpiece.
