た。2. Description of the Related Art When drilling holes for anchor bolts on a concrete floor surface, it is common practice for a worker to manually carry out a drill for drilling such as a vibration drill. Such a conventional drilling work method has a drawback that not only a skilled worker is required, but also one drilling requires a lot of labor. Further, variations in verticality and depth of the holes are likely to occur. Especially, when two holes for anchor bolts have to be formed at a small interval such as when installing a base plate at the lower end of a rack column, one operator must make two holes separately. In addition to being inefficient, it was also difficult to maintain high accuracy of the space between two holes and vertical parallelism.
