Ridgeback™ Blasthole Bits are the industry’s most innovative roller cone product for blast-hole applications. These products feature the patented Ridgeback feature, a bit body geometry which allows efficient evacuation of the drilled cuttings, improved drilling rates and extended bit life. The bearings and cutting structures of Ridgeback bits are optimized using mathematical models to ensure they deliver the lowest possible total drilling cost (TDC).Pilot Hole Bits
Varel International’s oil field and mining experience provide a selection of sealed bearing journal bits designed for drilling the most demanding raise bore pilot holes, blind bore pilot holes, and underground drill and blast holes.
