Patent Pending Lock Mechanism
The mass balanced, concentric design of the cutter blocks and
mandrel piston minimizes vibration.
Strategic positioning of the PDC cutters disperses work rates more evenly across all stages of the cutter block.
Gauge trimmers control cutting depth during each
rotation.
RipTide’s cutter block patented locking
mechanism reduces vibration and increases
stability

Controller
• The RFID R&D is a Weatherford – Marathon JV.
• Application & Benefits:
– Multiple & selective “open / close” actuation
– Dual RipTide drilling reamers in the BHA
– No affect on bit, RSS, or MWD/LWD hydraulics
