Atlas Copco RC45, RC50 Button bits 130mm 143mm Drop Center Fast Drilling
REVERSE CIRCULATION PERFORMANCE TOOLING
Reverse Circulation (RC) drilling is used to collect rock samples quickly and efficiently using a large rotary drill and air compressor. The high speed and lower cost per meter of RC drilling makes it ideal for obtaining mineral samples in the early phases of an exploration project.
Features:
1. Using higher grade carbides for longer life;
2. Minimizes hole erosion in fragile formations
3. Drills faster through soft formations with less blockages
4. Drills straighter through consolidated and unconsolidated formations
