GUIDE MECHANISM FOR POWER DRILL

摘要

An integral guide mechanism (2) for a power drill (1) which has retractable arms (10, 11) cooperating with the housing of said power drill. A workpiece engaging base (14) is on the retractable arms. The retractable arms enable retraction of the base towards the housing of the power drill past the chuck (6) and a catch arrangement holds them retracted. The base of the guide mechanism has a seat (20) to enable the base to be stably positioned against a pipe or other non-planar surface. The seat can include V blocks (24) to be positioned on the side of the base opposite to which the drill bit approaches or be positioned on the same side from which the drill bit approaches to cradle an article to be drilled.
