XY Core Drilling Rig

Hydraulic Core Drilling Rigs / Geotechnical Exploration Small Water Well Drilling Rig Machine

Bore hole water well drilling machine is a kind of widely used portable drill machine. Water well drilling rig is suitable for drilling water well, geological survey, geological core drilling, small grouting holes, blasting holes of railway, water conservancy, bridges, dam foundation and other buildings. According to different strata, it drills by choosing different bits, such as, diamond composite films and alloy.


Main features
1. It improves drilling efficiency and reduces labor intensity with hydraulic automatic feeding mechanism
2. It can be achieved without stopping to change rods, easy to operate, safe and reliable with ball clip holding mechanism or hydraulic chuck.
3. It has hole bottom pressure gauge to be easy to master the situation in the hole
4.It also has advantage of compact structure,concentrated handle, small footprint, light weight, strong decomposition, easy to move. It can be operated in plains and mountain areas.
