Explore the four main types of drill rigs: rotary, percussion, auger, and core. Compare their operating methods, sampling capabilities, and limitations, then learn how to choose surface, heli-portable, or underground core drilling equipment for your geology, access conditions, and project requirements.

Compare hard rock core drills and standard core drills for competent formations. Learn how geology, diamond bits, hydraulic control, core recovery, and cost per accepted meter shape equipment selection—and what to ask CORTECH when specifying a fully hydraulic wireline diamond core drilling system.

Who manufactures drilling rigs depends on the drilling purpose, geology, and required sample quality. This guide explains how to evaluate core drilling rig manufacturers, compare surface, heli-portable, and underground drilling solutions, and select a reliable full-hydraulic wireline diamond core drilling system from CORTECH.

This article compares permafrost drilling and tropical exploration lens, explaining how extreme climates affect rig selection, hydraulic performance, logistics, safety, and core recovery. It includes a side-by-side comparison, practical checklist, CTA, FAQ, references for content enhancement.

Closed-loop and open-loop hydraulic systems both play important roles in core drilling machines, but they solve different problems. This article compares their structure, performance, maintenance demands, heat behavior, and best-use scenarios for modern core drilling rigs.

This article examines how diesel-hydraulic and electric-hydraulic rigs power modern core surface drilling projects in 2026. It compares fuel and electricity cost structures, operator experience, and site scenarios, then outlines a practical framework and monitoring approach to help drilling fleets match rig architectures to specific project conditions and achieve more predictable cost per meter.

China has become a global hub for hydraulic core drilling equipment thanks to mature industrial clusters, competitive costs, and strong export capacity. This 2026 guide explains key supplier selection criteria and profiles 10 core drilling equipment manufacturers in China, including CORTECH, to help buyers secure reliable OEM/ODM partners.
