DFQ-100WA drilling and milling  machine is a lightweight,  high efficiency,  tractor mounted drilling
machine.  It can be applied into courtyard, indoor, greenhouse, underground car park, bridge opening, duct, tunnel and other strictly required working sites. This machine can be also used in water well drilling, irrigation wells, geothermal heat project and others. Especially suitable for the high efficiency required concentrated photovoltaic pole hole working.

This machine can drill in different geothermal conditions by compressed air DTH and mud pump. The drill tower lifting, drill pipes installation and uninstall, rotary, support legs, walking and other movements by fully hydraulic, which could decrease the labor intensity and increase the quality and efficiency of project.

 1. 30KW China famous electric motor, avoiding diesel engine's noice, air protecting, good to work in narrow space.
2. High strength DTH hammer drilling, specially powerful to drill hard rocks.
3. Adopt oil tank & chain structure, safe and reliable. Drilling pressure and speed an be adjusted to achieve the highest drilling efficiency and the longest lifetime of drilling bits. 
4.Four hydraulic support legs adjust the drilling machine to horizontal position quickly.
5. Air compressor equipped with high pressure air lubricator to prolong the DTH hammer's lifetime.
6.Compensated mode slide board protect the drilling pipe's screw thread when mount or dismount the drilling pipe and make the drilling pipe could be used for longer time.
7. Independent module design, allowing mounted on trucks to increase flexibility.

 Established in 1970s, Zhengzhou Defy has growned into one leading drilling rig manufacturer in China, specilizing in drilling rig technology R&D, manufacturing, etc. We spark on conventional rotary drilling rig, new pneumatic drilling rig and are inventing another drilling rig with performance same as pneumatic one, but with much less investment for users.
 
Our drilling rigs are widely used for water well drilling, irrigation well drilling, geothermal hole drilling, mining blast hole drilling, construction pile work drilling, air-conditioner hole drilling, etc.
 
DEFY Brand drilling rigs have been widely exported to Chile, Russia, Australia, Malaysia, Kenya, Tansanzia, Zambia, South America, Peru, Zimbabwe, etc.
 
Every customer is very welcomed to our factory for visiting driling rig,  talking onsite and details. ^_^

 How to choose a suitable drilling rig? 

1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?

2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more. 

3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.

4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one. 
C. Mainly hard rock, like granite.

Based on the above information, DEFY experienced engineers will help you recommend suitable machine and price. If you have special demands, please tell us ahead.
