A mining services company based in Saudi Arabia was struggling with a familiar problem. Their existing drilling rigs could not keep up with the demands of a large quarry project in the western region. The rock was too hard. The penetration rate was painfully slow. Breakdowns were frequent, and each hour of downtime meant lost revenue and delayed blasting schedules.
The company needed a solution that could handle the extreme conditions – ambient temperatures often exceeding 45°C, abrasive dust, and unrelenting basalt formations. After evaluating several options, they brought in a YGS350 down hole drilling equipment unit from YG Machinery.
The change was immediate. Penetration rates increased by more than 30% compared to their older machines. The contractor completed the quarry development two weeks ahead of schedule. The site manager later told us, “This is the first time we haven’t worried about our drilling rig shutting down in the middle of a shift.”

Three Challenges That Make Saudi Arabia A Tough Place To Drill
The Saudi contractor’s experience highlights three challenges that are common across the region’s mining, quarry, and construction sectors.
Extreme Heat and Dust
Summer surface temperatures in Saudi Arabia regularly exceed 50°C. Fine dust penetrates every opening. Standard drilling equipment overheats, hydraulic fluids break down, and air filters clog within hours. The result: constant unscheduled maintenance.
Hard, Abrasive Rock Formations
Much of Saudi Arabia‘s geology consists of dense basalt, granite, and metamorphic rock. These formations chew through conventional drill bits and put extreme stress on rotation systems. A down hole drilling rig that performs well in soft soil will struggle here.
Remote Job Sites with Limited Support
Warries and mines are often located hundreds of kilometers from the nearest service center. When a machine breaks down, waiting for a technician can cost days of lost production. The equipment must be robust enough to keep running without frequent professional attention.
These are not minor inconveniences. They are the difference between a profitable project and a financial loss.
Why The YGS Series Down Hole Drilling Rig Is Built For Saudi Conditions?
The YGS350 down hole drilling equipment used by the Saudi contractor was designed specifically to address these extreme conditions.
Heat-Resistant Components
We equip each drilling rig with high-temperature hydraulic seals and oversized cooling systems. The 73.5kw YC4DK100-T304 engine maintains stable power output even when ambient temperatures exceed 45°C. The 225L diesel tank reduces refueling stops, which matters when the nearest fuel station is two hours away.
Heavy-Duty Drilling Power
With a maximum drilling diameter of 165mm and a horizontal hole height of 3.5 meters, the YGS350 punches through hard basalt that stops lighter rigs cold. The 8-ton weight provides stability, reducing vibration that would otherwise wear out drill pipes and couplings.
Simple, Field-Friendly Maintenance
Air filters use a two-stage cyclone design that throws out most dust before it reaches the filter element. Grease points are grouped in accessible locations. The electrical system uses color-coded wiring and labeled components, allowing a site supervisor with basic mechanical knowledge to handle minor repairs.
The Saudi contractor’s team learned the daily maintenance routine in one morning. They have not needed a factory technician on site since the rig arrived.
Real Results From The Saudi Quarry Project
The numbers from the Saudi project tell a clear story.
- Penetration rate: Increased by 30% compared to the contractor’s previous down hole drilling equipment.
- Downtime: Reduced by more than half. The YGS350 completed three months of continuous operation with only scheduled maintenance stops.
- Fuel efficiency: The 225L tank allowed two full shifts of drilling before refueling, compared to three refueling stops per day on the old rig.
- Project completion: The quarry development finished 14 calendar days ahead of the original schedule.
The site manager’s feedback was direct: “We have tried three other brands. None of them lasted a full month in this environment without a major failure. The YG rig is still running like the day it arrived.”
Another operator on the crew added, “The controls are straightforward. I was productive after two hours of practice. The dust collection system keeps the cab clean, which never happened on our old down the hole drilling rig.”
Ready To Upgrade Your Drilling Operation?
The Saudi market does not forgive weak equipment. High temperatures, abrasive dust, and hard rock separate reliable machines from the rest. The YGS series down hole drilling equipment has proven itself in exactly these conditions.
YG Machinery has shipped drilling rigs to contractors across the Middle East, Africa, Southeast Asia, and South America. We provide specification guidance, operator manuals in English and Arabic, and a stock of common spare parts for fast shipment.
Do not let another project suffer from slow penetration rates and unexpected breakdowns.
