A. Range of application
(1)Geological exploration; engineering geology investigation and kinds of survey hole in concrete structures.
(2)Diamond bits, hard metal bits and steel-shot could be selected to different layers.
(3)The drilling depth which is 100m or 180m must be suitable for the final hole dia 75mm 0r 46mm. The drilling depth can? not exceed its 110%.

B. Feature of the drill
(1)Easy operation and high efficiency as the hydraulic feeding be taken.
(2)As the ball type chuck and the driving rod, it can complete no-stopping rotating while the spindle relift.
(3)The pressure indicator of bottom hole can observe and control the well conditions easily.
(4)Close levers, convenient to operate.
(5)Compact size and light in weight are easy to set up and transport on working plains and mountain area.
