Numa Drilling

What Is Numa Drilling?

Numa drilling refers to a high-impact, large-diameter Down-The-Hole (DTH) drilling system widely used in:

• Mining (iron ore, gold, copper etc)
• Water well drilling
• Foundation piles & bridge caissons
• Oil & gas pre-drilling
• Geothermal wells
• Quarry blasting holes
• others

NUMA systems are known for:

• Massive energy output
• High airflow capacity
• Extra-large bit sizes (10"–32")
• Superior penetration in extremely hard formations

In simple words:

👉 If the job demands BIG holes, DEEP holes, or TOUGH rock-NUMA drilling tools stand out.

Key Features and Advantages of Numa Drilling

1. Versatility Across Many Drilling Applications

NUMA drilling is favored because it performs consistently across:

• Boulders
• Basalt
• Granite
• Sandstone
• Limestone
• Mixed formations

Operators love its adaptability: fewer bit changes, fewer delays, better consistency.

2. High Penetration Rates

NUMA-style hammers deliver:

• Large piston mass
• High impact frequency
• Optimized air pathways
• Superior energy transfer efficiency

---

3. Durability in Rugged Environments

NUMA tools are engineered for environments where:

• Drilling shocks are extreme
• Abrasive formations wear down carbide aggressively
• Large compressors run continuously

Leanoms' NUMA hammers use:

• Heat-treated alloy steel
• Heavy-duty internal components
• Wear-resistant guiding surfaces
• Precision machining

This results in extended hammer life and predictable performance.
