HF-30 portable sampling drill is a full-automatic sampling drill which combines various drill features and is improved all the time. The power source of the drill is gasoline engine, its rewinding is driven by hydraulic pressure, then the cylinder adds pressure to satisfy large range of load change and reliable running.

According to various geological conditions, you can choose diamond, alloy or steel particles drilling bit for drilling. You can also practice drill pile feeding as non-stop then the efficiency will be high. Centralized handles make operation easy. Compact structure, small volume, light weight, easy to disassemble and move lets it fit to work in flat and mountain areas. Its reliable function, complete coring and flexible operation are fit for field work, then improve the efficiency and decrease the sampling cost, which has reached international advanced grade.

Applications
HF-30 portable sampling drill is mainly used in drilling and borehole sampling projects like geochemical prospecting &sampling, areal geological mapping, ore vein survey in shallow surface and sap, geophysical prospecting epicenter hole construction, geotechnical engineering and so on.

Main features
(1) Employ gasoline engine as power, fit for sampling & drilling as no power outside
(2) Rewinding driven by hydraulic pressure, meet loading change in a large range, reliable running
(3) Smart and light, good disorganization, move easily, fit for wild field long distance traveling
(4) Simple operation, easy to study and master, practical and reliable.
