Drill guide for hand-held drill

A drill guide for a drill bit of a chucked hand-held drill including a chuck operable to retain the drill bit in the chucked hand-held drill, the drill guide comprising:

• a mount configured to couple to a non-rotating portion of the chucked hand-held drill;
• a coupler including a twist-to-lock mechanism configured to removably affix the coupler to the mount, the coupler forming a chuck access window in an exterior surface of the drill guide, the chuck access window aligned with the chuck when the mount is coupled to the non-rotating portion of the chucked hand-held drill thereby allowing a chuck key to be inserted through the exterior surface of the drill guide and interface with the chuck;
• a telescoping guard extending from the coupler and configured to telescope into a retracted position from an extended position;
• and
• a guide foot coupled to the telescoping guard opposite the coupler such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, wherein the drill bit passes through the guide foot as the telescoping guard telescopes into the retracted position from the extended position.
