A Yemeni customer ordered a Core Drilling Machine for Sale. The unit was delivered, installed, and is now in daily use. The team reports high drilling speed and stable cores that meet project needs.
Customer Background And Purchase Process
The client works in infrastructure construction. They handle roads, bridge repairs, and public buildings. Their labs also test material samples from job sites. They needed a machine that could drill concrete for quality checks and also take rock cores for foundation evaluation.
The buyer searched on Google using phrases like “core drilling machine for sale” and landed on YG’s product page. After sending an inquiry, our product manager called to learn more:
What core diameters and depths were required?
What power supply is available on site?
How soon is delivery needed?
Based on the answers, we proposed a compact stand-type core drill for concrete and asphalt, plus a portable rig package for shallow rock coring. We showed torque curves, speed ranges, and real project photos. We also explained drill bit selection and water management. After a short technical review on video call, the client confirmed the order.
Core Drilling Rig Machine — Project Requirements In Yemen
The Core Drilling Rig Machine had to meet mixed tasks:
Take concrete cores from bridges, tunnels, and slabs.
Drill asphalt layers on roads for lab tests.
Extract shallow rock cores near foundations and slopes.
Work in hot, dusty conditions with stable performance.
Move quickly between urban and remote sites.
To match these needs, we configured a robust base, a high-torque motor, a three-speed gearbox, and wet drilling accessories. This solution kept the machine steady and cool during long runs.
