HY-F40 Flush Drill (Mini Drill)

Specifications are subject to change without notice.

The drilling machine is a kind light type drilling machine which used in soft ground, rivers, farmland, swamp area. The drilling machine drills holes by manually operated, the swivel weight is very light, not more than 20 kg. Centrifugal type pump provide mud flushing supporting the drilling. With the advantages of quick transportation, low cost, it is suit to mass production for 2D seismic operation.
