Well Cleaner® RCB

Reverse Circulating Bit

Introduction

Well Cleaner® RCB (Reverse Circulating Bit) integrates both a rotary bit with a suction system to provide the combined benefits of both in one powerful tool. This design breaks through hard packed debris and recovers the generated cuttings with suction into the integrated bailers. In one run you can crush mineral deposits like cement and remove them from the well to prevent further associated problems.
