Product Features
1.Rapid removal of cuttings;
2.No use of drilling mud;
3.High penetration rate, especially in resistant rock formation ;
4.Easy soil and groundwater sampling during drilling;
5.Possible to measure yield estimate at selected depth in the formation;
6.Advantageous in unconsolidated formations with a high risk of caving .

Application Range
It is suitable for drilling water wells, geothermal wells, short mircopiles ,medium mini-type grouting hole of building,dam and harbour project.
1. When drilling starts , the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly
2. When the required depth is reached , rotation is reversed carefully, whereupon the reamer swings in , allowing the drill bit assembly to be pulled up through the casing.
3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
