Abstract
A dental drill (10) defining a bore diameter and a drill stop sleeve (22) which is transparent or translucent, thereby improving the view of the drilled hole formed by the drilling during the operation. The drill stop sleeve (22) comprises an uninterrupted circumferential lip (34), which interacts with a groove (24) formed in the shank part (16) of the dental drill (10) and thus fixes the drill stop sleeve (22) on the dental drill (10). The drill stop sleeves (22) of equal length are held in a blister of a set, the blister having, for each drill stop sleeve (22), a specific receiving recess that is closed in a sterile manner. Each blister comprises several drill stop sleeves with sleeve diameters corresponding to the bore diameters.
