133mm RC45 HD Reverse Circulation Hammer Drill Bit

High-performance drilling spare parts for rock drilling machines and DTH bits

Reverse Circulation Drilling Technology

Reverse Circulation (RC) drilling utilizes dual wall drill rods consisting of an outer drill rod and inner tube. The hollow inner tubes enable continuous, steady transport of drill cuttings back to the surface using compressed air, making this the preferred method for initial exploration.

Key Features & Advantages

Optimized internal structure based on extensive hammer experience, ensuring fast, smooth drilling with continuous sampling
Simple internal design with high-rigidity components for extended service life and easy maintenance
Integrative collection tube design allows replacement without disassembling the hammer, featuring carburizing treatment for superior abrasion resistance
Patented drill bit design enables drilling different hole sizes with the same hammer, preventing sample contamination
Effective performance in challenging conditions including loose soil, hard rock, and water-rich environments
