A drill box includes a transparent housing, and two elongated supporting members, each of which includes a supporting portion having several through locating holes spaced along it. Each of the through locating holes has a lower opening shaped such as to allow a shank of a drill to be tightly inserted therein, and an upper opening bigger than the lower opening. The supporting members are stacked up so that confining space is formed for holding the sharp bodies of drills therein. The supporting members have concavely curved surfaces around each of the lower openings for allowing one end of a shank of a drill to stick out from the lower opening after the shank is inserted into the locating hole. The elongated supporting members are slid into the housing so that the drills held on them are protected.
