NQ 1000M UN1000 Underground Core Drilling Rig With Max Torque 1650Nm

The UN1000 Tunnel Core Drill Rig by SINOCOREDRILL is an advanced, highly reliable hydraulic drilling system designed as a superior alternative to imported tunnel drilling equipment. Engineered for both underground tunnels and surface exploration, the UN1000 is capable of handling a wide range of drilling applications, including core exploration, ventilation drilling, dewatering boreholes, grouting operations, and multi-angle geological investigations.

With cutting-edge hydraulic control technology and an operator-friendly design, the UN1000 significantly improves drilling efficiency, reduces operational risks, and enhances equipment lifespan. It is the ideal choice for contractors seeking powerful, durable and cost-effective tunneling equipment.

Outstanding Control & Safety System

The UN1000 integrates a synchronized power head chuck and rod holder, ensuring fully coordinated operation and eliminating drill pipe dropping accidents caused by human error.

A single operating handle allows the operator to easily complete:

• Thread make-up

• Thread break-out

• Rapid feeding

• Rapid retraction

The system is equipped with an automatic floating mechanism to protect drill rod threads during make-up and break-out, significantly lowering rod consumption costs.

Three Intelligent Drilling Modes

To meet different underground drilling needs, the UN1000 features three coordinated operation modes:

1. Drilling Mode

2. Rod Feeding Mode

3. Rod Retrieving Mode

All three modes achieve automatic cooperation between the power head chuck and rod holder, effectively doubling working efficiency and improving safety in confined tunnel environments.

Bidirectional Pressure Feeding System

The UN1000’s main hydraulic cylinder applies pressure in both pushing and pulling directions, making it suitable for:

• Highly fractured ground

• Squeezing rock strata

• Upward and downward angle drilling

• Long borehole stability

Unlike traditional drilling rigs that rely on single-direction pressure adjustment, the UN1000 eliminates complex weighting procedures, reducing operator workload and improving construction efficiency.

Key Features of the SINOCOREDRILL UN1000
