ABSTRACT:
A drill or machine tool attachment for use with a vacuum debris extraction system, comprising a bar to which a vacuum extraction nozzle is attached, and a tube slidably mounted on the bar and connected to a drill or machine tool. The nozzle is located on the bar ahead of the drill or machine tool, with the tube biased toward an extended position by at least one spring. The limit of the extended position is set by a locking plate. In use, as the apparatus is offered up to a workpiece to perform a drilling or machining operation, the nozzle makes initial contact with the surface of the workpiece and as the operator applies pressure to the assembly, the drill or machine tool and associated bit or tool moves slideably against the action of the spring thereby guiding the bit or tool through an aperture in the nozzle to contact the workpiece.
