REVERSE CIRCULATION BITS
Roschen range of high quality Reverse Circulation RC drill bits were specifically designed to work with our RC Hammers. Because of our drill bit sealing mechanism, sample contamination problems are not an issue. Using our unique 12 spline shank design, these RC Bits provide outstanding performance and reliability.
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
