"EP" & "SP" series drills have innovative drilling system giving the roation and vibration to drill bit simultaneously and offer remarkable drilling efficiency compared with hydraulic percussion drill in consideration of neighboring environment thanks to its low noise creation. These drills are capable of high speed sampling to collect undisturbed samples without the use of circulation fluid, furthermore, can conduct the sampling and drilling of monitoring well at same time by means of dual tube method.
SONIC drill has an innovative drilling technology providing the rotation and vibration with drill bit. Compared with conventional rotary method, DTH hammer method or rotary percussion method, remarkable high speed drilling is realized.
