1.Compact size and light in weight are easy to set up and transport on working plains and mountain area.
2.long diameter of vertical shaft,long distance of stand and good rigidity.
3.Kelly bar to ensure torque transmission.
4.high speed and suitable range of speed to meet varies need of small diameter diamond drilling or large
tungstem-carbide drilling.
5.feeding pressure and speed can be adjust to meet various stratum.
6.pressure gauge for obtain information abount hole bottom.
7.easy operation and maintance.
