Feature:

• Conical Rock Auger Pilot Design
  The pilot provides accurate positioning, while the conical structure enables efficient penetration into hard rock and tough ground conditions during rotary drilling.

• Double-Cutter Design for Stable Drilling
  The double-cutter configuration provides uniform cutting force and improves drilling stability, helping reduce hole deviation during rock drilling.

• Double- and Single-Spiral Design
  The double spiral efficiently carries excavated soil and rock cuttings. For cohesive soil conditions, the single-spiral design makes spoil discharge easier and more efficient.

• Cast Pilot with Rock Drilling Bits
  The cast pilot is equipped with high-strength rock drilling bits, providing excellent wear resistance and reliable performance in rock drilling applications.

• Staggered Rock Drilling Bit Arrangement
  The rock drilling bits are arranged in a staggered pattern to improve cutting efficiency, optimize rock penetration, and extend drilling tool service life.

• Designed for Various Rock Conditions
  The Conical Rock Auger is suitable for medium-weathered rock, bedrock, weakly fractured rock, and other challenging geological conditions in foundation drilling and piling construction.

Advantages:

1. Optimized Drilling Tooth Angle

The optimized drilling tooth angle improves cutting efficiency and penetration performance. Our Conical Rock Auger is designed to provide stable and efficient rock cutting during rotary drilling and foundation piling applications.

2. Heavy-Duty Rock Drilling Teeth

For hard rock, rocky terrain, and hard soil conditions, the auger is equipped with reinforced rock drilling teeth. These heavy-duty teeth are manufactured from wear-resistant materials to withstand high impact, abrasion, and demanding rock drilling applications.

3. Hard-Facing for Enhanced Wear Resistance

Hard-facing strips are integrated into the rock drilling auger to provide additional wear protection. This design significantly improves wear resistance and extends the service life of the rotary drilling tool when working in abrasive rock and tough ground conditions.

4. High-Strength Tungsten Carbide Drilling Teeth

The drilling teeth feature high-strength tungsten carbide materials for excellent hardness, wear resistance, and rock penetration performance. A forged round holder and center-positioning design provide reliable tooth support and improve the overall durability of the rock auger drilling tool.

5. Double-Spiral Conical Structure

The double-spiral conical structure provides excellent guidance, stability, and spoil transportation during drilling. It helps maintain drilling direction and improves soil and rock removal efficiency, making the Conical Rock Auger suitable for rotary drilling rigs and foundation drilling.

6. Advanced Manufacturing and Quality Control

With a modern manufacturing workshop, advanced production equipment, and automated robotic welding technology, we maintain strict quality standards throughout the production of our rotary drilling tools. Advanced manufacturing processes ensure high precision, structural reliability, and consistent performance for rock drilling and piling applications.
