ABSTRACT:
A swarf boot comprises a flexible and elastic, generally frusta-conical, unitary member for capturing swarf, cuttings, dust and debris from drilling operations. The boot has two open ends, namely a proximal end adapted to receive and hold a drill body, and a distal end adapted to engage a surface to be drilled. In between the two ends, the swarf booth comprises a generally frusta-conical, corrugated body. The drill chuck is received within the interior of the boot. The inside dimension of the boot is substantially larger than the outside diameter of the chuck. Thereby, the boot surrounds but does not come in contact with the drill chuck, allowing the chuck rotate freely while the boot of the invention remains stationary. Optionally, the boot may include a outlet conduit for attachment to a vacuum to remove swarf during drilling operations. The boot may also include a handle on the distal end of the boot.
