RADIAL DRILLING MACHINES
BENCH-TYPE DoALL's DTR-28 bench-type radial drilling machine combines the sophistication of a radial drill with the simplicity of a drill press. It features an articulated radial arm and a large diameter motorized column which can be easily raised or lowered. A pneumatic locking system ensures rigid locking of column and head in any position. Because of this design it can take on complex multiple position drilling and tapping jobs and is especially useful where conventional drilling ma- chines are not adaptable enough or where drilling and tapping operations are required on a workpiece in the same position.
