A single-piece snap-on interchangeable dental surgical drill stop device comprising:

• a single-piece snap-on drill stop having two ends, a first end adapted to taper fit to a hand grip drill handle, the first end partially adapted to the hand grip for rigidly snap-coupling the drill stop device with the hand grip drill handle;
• the snap-on drill stop first end having a midsection elbow bending into and permanently continuous to an open drill stop cuff-like collar element with center disposed co-axial to a drill bit and conformably fitting to a drill assembly drill bit, the collar element extruding and permanently coupled to and protruding into the open drill stop cuff-like collar element at the distal second end, and
• the snap-on drill stop second end having a drill bit parallel neck permanently continuous with the elbow midsection and collar element to a length short of the drill bit distal end with the open drill stop cuff-like collar element providing an impediment to any drill bit progress into a drill bit normal surface,
• whereby the snap-on drill stop device can be inserted and/or removed manually without removing the drill bit and where the drill depth is quickly ascertainable by inspection of the protruding distance below the open drill stop cuff-like collar element.
