Abstract

An anchor bolt insertion system for e.g. masonry walls, employs a special drilling tool (19, 16, 17, 18) driven by a power unit (26) at the rear, mounted on a base (27) with a contactor (28) which locates on the face of the wall, so that a hole (2) is drilled by the cutting tip (15) to a depth less than the combined length of the anchor bolt and its attachment head. Then a further cutter (16) of a larger diameter counterbores a further hole portion (3) suitable to house the attachment head, the entire hole then being equal to the combined length of the bolt and its head.
