Abstract

The stone drilling apparatus has a drill support frame (1, 7) with a portable electric drill (2) moved towards and away from a stone slab (P) by a rack (4) and pinion (5) controlled by a hand wheel (6) support frame bars (7) forming runners for drill motions. A screw mechanism (12, 13) operated by a hand wheel (14) moves the drill (2) over the slab (P). The drill is mounted on a column (3) fixed to the slab by suction cups (19). The column (3) pivots w.r.t. its base (16, 19) permitting angular drill orientations with the pivot (17) locked by a lever (18). A single lever (20) controls operation of the suction cups.
