SEALED BEARING ROLLER REAMER

The ROSCHEN Oilfield Oil Sealed Roller Reamer is designed with industry-leading, field-proven roller reamer technology and wedge-lock cutter-retention mechanisms for use under harsh (drilling fluid and high temperature/pressure) downhole conditions, extended on-bottom run and both forward reaming and backreaming operating modes.
 

It delivers superior performance and reliability, to provide on-guage reaming action across changing rock type and well construction application. It is available for near-bit and string BHA configuration.
