Rotary Borehole Drilling Rigs
Rotary borehole drilling rigs are used for efficient water well and groundwater drilling through soil, clay, weathered formations and other suitable ground conditions. Depending on the project, rotary or rotary-cum-DTH configurations can be used to match changing geological conditions. Riggers International manufactures and supplies rotary borehole drilling rigs for agricultural, commercial, industrial and water development projects. Rig selection depends on drilling depth, bore diameter, ground formation, circulation method and site access.
Rotary Drilling Technology
Rotary drilling advances the borehole through continuous rotation of the drill string and drilling tool.
In mud-rotary applications, drilling fluid circulates through the borehole to help carry cuttings to the surface and support the hole during drilling.
Where formations change from softer ground to hard rock, selected rotary-cum-DTH rigs can provide additional flexibility by supporting both rotary and DTH drilling methods.
Types of Rotary Borehole Drilling Rigs
Compact Rotary Drilling Rigs
Suitable for smaller projects and restricted-access locations where machine dimensions and manoeuvring space are important.
Truck-Mounted Rotary Rigs
Designed for contractors requiring easier road transport between commercial and groundwater drilling sites.
Tractor-Mounted Rotary Rigs
Practical for farms, irrigation projects and rural drilling locations where tractor-based mobility is suitable.
Rotary-Cum-DTH Drilling Rigs
Combine rotary and DTH drilling capabilities for projects where ground conditions may change during drilling.
Rotary Water Well Drilling Rigs
Suitable for water well and groundwater projects in soil, clay, weathered and other compatible formations.
Applications of Rotary Borehole Drilling Rigs
Mixed Formation Drilling
Rotary-cum-DTH configurations can be considered where drilling progresses from softer formations into harder rock.
Commercial and Industrial Boreholes
Used for groundwater projects at factories, commercial properties, construction sites and industrial facilities.
Geological and Investigation Drilling
Selected rotary rigs can support suitable site-investigation and subsurface drilling applications.
Residential and Community Water Wells
Suitable for groundwater development serving homes, villages, schools and community facilities.
Agricultural and Irrigation Wells
Used for farms, plantations, irrigation systems and livestock water-supply projects.

How to Select a Rotary Borehole Drilling Rig
Mounting Configuration
Truck-mounted, tractor-mounted or other configurations should be selected according to transport, terrain and site-access requirements.
Rotary-Cum-DTH Requirement
Where harder formations may be encountered, a combination rig can provide flexibility to change drilling methods when suitable.
Mud-Pump Requirements
Where mud rotary drilling is used, the pump should provide suitable circulation for cuttings removal and borehole conditions.
Ground Formation
Soil, clay, weathered formations and mixed ground may require different drilling tools and circulation arrangements.
Drilling Depth and Bore Diameter
Required depth and bore size influence rig capacity, rotary torque, drill rods and supporting equipment.
Rotary Torque and Speed
Torque and rotation speed should match the drilling tool, bore diameter and expected formation.

Frequently Asked Questions
1. What is a rotary borehole drilling rig?
A rotary borehole drilling rig uses continuous rotation of the drill string and drilling tool to create water wells and other boreholes.
2. Is a rotary drilling rig suitable for hard rock?
Standard rotary drilling is generally used according to the formation. Where hard-rock sections are expected, a rotary-cum-DTH configuration may be more suitable.
3. What is the difference between rotary and DTH drilling?
Rotary drilling mainly uses continuous rotation, while DTH drilling combines rotation with pneumatic hammer impact at the bottom of the borehole.
4. Does a rotary borehole drilling rig need a mud pump?
Mud rotary drilling commonly requires a suitable mud pump for drilling-fluid circulation and cuttings removal.
5. Can rotary drilling rigs drill different borehole diameters?
Yes. The available diameter range depends on rig capacity, rotary head, drill rods, drilling tools and circulation system.
6. Can a rotary rig be tractor-mounted?
Yes. Tractor-mounted rotary rigs can be suitable for agricultural and rural drilling projects where tractor mobility is practical.
7. What affects rotary borehole drilling rig price?
Price depends on drilling capacity, rotary torque, hydraulic system, mounting configuration, mud-pump requirements, drill rods and additional equipment.
8. What information is needed for a rotary rig quotation?
Provide the required drilling depth, bore diameter, ground formation, project location, preferred mounting type and whether mud-pump or DTH equipment is required.
