Depth gauge for drill bit

A depth gauge for use with a drill bit, comprising:

• a body configured to receive a drill bit;
• a retention mechanism coupled to the body and configured to removably couple the body to the drill bit;
• and
• a cap configured to be removably coupled to the body in one of a first position relative to the body where the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a first depth, and a second position relative to the body where the cap contacts the workpiece surface to prevent the drill bit from entering the workpiece more than a second depth that is different from the first depth,
• wherein the cap has a first contacting surface at one end thereof and a second contacting surface at an opposite end thereof, such that when the cap is in the first position, the first contacting surface contacts the workpiece and when the cap is in the second position, the second contacting surface contacts the workpiece.

A depth gauge for use with a drill bit, comprising:

• a body configured to receive a drill bit;
• a jaw coupled to the body and configured to removably couple the body to the drill bit, the jaw moveable between a locked position in which the jaw engages a groove in the drill bit and an unlocked position in which the jaw is disengaged from the groove in the drill bit;
• an actuation sleeve coupled to jaw and selectively moveable in only a single unlocking direction from a first position in which the jaw is in the locked position to a second position in which the jaw is in the unlocked position;
• a supplemental locking sleeve coupled to the actuation sleeve and selectively moveable between a third position that enables the actuation sleeve to be selectively moved between the first and second positions, and a fourth position that prevents the actuation sleeve from being moved between the first and second positions;
• and
• a cap coupled to the body in one of a fifth position relative to the body where the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a first depth, and a sixth position relative to the body where the cap contacts the workpiece surface to prevent the drill bit from entering the workpiece more than a second depth that is different from the first depth.
