The Characteristics of RC hammer and bits

The RC bits are the tool cutting rock. SHANDIKE RC DTH bits are made of superior quality alloy steel and T.C carbides.

Advantages of the RC system

1. Reverse Circulation Technology
– Utilizes a unique air/fluid circulation system that transports cuttings upward through the center of the drill string, ensuring clean and uncontaminated samples.
– Minimizes hole deviation and improves drilling accuracy in fractured or unstable formations.

2.High-Performance Design

– Carbide Button Configuration: Strategically placed tungsten carbide buttons for maximum impact energy transfer and extended bit life.

– Optimized Flushing Channels: Ensures efficient removal of cuttings and reduces balling in sticky formations.

3. Durability & Adaptability

– Manufactured from premium-grade alloy steel with advanced heat treatment for exceptional wear and impact resistance.

– Compatible with a wide range of rock types, including hard, abrasive, and highly fractured formations.

4. Easy Maintenance

Modular design allows for quick replacement of worn components, reducing downtime and operational costs.

Technical Specifications
– Drill Bit Diameter: 90mm to 350mm (custom sizes available).
– Connection Type: Standard API or custom thread options (e.g., R32, COP, etc.).
– Operating Pressure: 15–30 bar.
– Impact Frequency: 1,200–2,400 blows per minute (BPM).
– Material: High-strength steel body with tungsten carbide inserts.

Applications
– Mineral Exploration: Achieves high-quality core samples for accurate resource evaluation.
– Water Well Drilling: Efficiently penetrates hard rock layers while maintaining borehole stability.
– Geotechnical Surveys: Ideal for soil and rock sampling in complex geological conditions.
– Blast Hole Drilling: Enhances productivity in quarrying and mining operations.

Advantages Over Conventional DTH Bits
✅ Higher Penetration Rates: Optimized energy transfer ensures faster drilling.
✅ Cleaner Samples: Reverse circulation minimizes contamination for precise analysis.
✅ Reduced Air Loss: Sealed design prevents air leakage, improving energy efficiency.
✅ Extended Service Life: Robust construction reduces wear in abrasive environments.
