Product Description
DF-Y-2 hydraulic exploration core drills

I.General Description of DF-Y-2 Core Drilling Machine:
DF-Y-2 Core Drill is up-dated designed according to the development of geological works to meet the needs of 
users.It is a new type spindle core drill rig. It is applied for engineering geological exploration drilling, hydrogeology
well drilling and big-hole basic engineering drilling including core drilling with tungsten-carbide tipped and diamond
bit mainly. 
II.Characteristics of DF-Y-2 Core Drilling Machine : 
1. Light in weight, easy relocation. 
2. Adopting traversal winch, this will overcome the fault of wire arbitrary intertwine and quick wearing out of the 
winch laid in length ways. 
3. Belt transmission is adopted for the high speed level to make the drill soft in the uneven formation, and reduce
the damage to the components and other mechanical failure. 
4. In large spindle hole. 
5. With wide speed range and large torque moment in lower speed, it is suitable for engineering geological 
subterranean and water explorations. 
6. The rig is stable in relocation and firmly for position. 
7. Debuts F3L 912 diesel engine or 22Kw electric motor for your selection.
