Viper RockReamers
The new Viper RockReamer is designed in part
to alleviate the epidemic of split-bit reamers
catastrophically losing cutters down hole. The
Viper provides added strength and the best
possible down-hole cutter security in addition
to longer hours, smoother rotation, and better
penetration rates.
V8: 8-1/2″ Min. Pilot
