Pneumatic Column Drilling Machine
A power unit drilling machine, which uses high-efficiency spiral drill rod and carbide drill bits to work.
Widely used in detecting, discharging gas and water in drilling work. Its rotation direction is reversible, It adopts independent motor with powerful feed force and a little malfunction. The feeding speed is regulated by controlling the air volume. Operation panel is separated from the main frame, which means that it can be control led in a far distance. The special double silencer makes the lowest noise, The Main frame, bracket and operation panel is easy to remove.
