Abstract:
A drill guide apparatus for guiding a drill bit along a path that is axially aligned with an edge of a piece of material, said apparatus comprising:a guide block for guiding the drill bit along the path, said guide block having a guide bore extending through an upper and lower surface of said guide block, said guide block having a first end and a second end; and a base block for moving along an edge of the work piece, said base block being mounted on said guide block to set a distance between said guide bore and said base block for establishing a separation between said path and the edge of the work piece, wherein said base block is movably positionable on said guide block such that said distance between said guide bore and said base block is adjustable for establishing a separation between said path and the edge of the work piece, said base block having a protruding member and said guide block having a channel extending in said lower surface of said guide block, said protruding member being removably slidably mounted in said channel; wherein said channel extends from the first end of said guide block toward the second end of said guide block, said channel terminating in a blind end short of said second end such that said channel does not communicate with said second end, said guide bore being located between said blind end of said channel and the second end of said guide block for preventing said protruding member and said base block from passing through a longitudinal axis of said guide bore.
