Water Well Drilling Rig
DR300
Features
One Rig for Different Hole Requirements
Different projects call for different borehole sizes. This rig can be configured for multiple hole diameters, allowing contractors to adapt the drilling setup to the required well design or installation task instead of relying on a single fixed hole size.
Efficient Drilling for Repetitive Hole-Making
The drilling system combines controlled rotary power with hydraulic feed to maintain steady penetration. This makes the machine well suited to projects where contractors need to complete multiple holes efficiently, such as water wells, planting holes and utility pole holes.
HStable Rotary Power Across Changing Ground Conditions
The rotary system is designed to maintain useful torque while the drilling conditions change. This helps the operator keep the drilling process controlled when the formation becomes harder or the resistance at the bit increases.
Easy Access to Challenging Jobsites
The machine combines a compact overall footprint with strong climbing capability, making it easier to reach jobsites with uneven ground, slopes or restricted access. This is particularly useful when drilling locations are away from paved roads or established infrastructure.
