Rhino XM
On-demand multiactivated reamer
Achieve more reliability with a truly on-demand hydraulically activated reamer—more reliable than third-party reamers.
Rhino XS
Hydraulically Expandable Reamer
Single ball drop activation
Reliable operation control
Dual reamer capability
Tandem undereamer BHA with dual Rhino XS
Multiple cutting structure configuration
Application specific cutter block configuration
Superior borehole quality
The Rhino XS hydraulically expandable reamer can be configured for a wide range of borehole sizes and borehole enlargement applications, including extended intervals drilled with advanced rotary steerable systems (RSS), extended-reach (ERD) wells, highly abrasive formations, and loosely consolidated formations.
Application-specific and robust construction
The single-piece body of the Rhino XS reamer enables a higher tensile- and torque-load capacity. The tool features a symmetrical, concentric arrangement of three PDC cutter blocks that improve ROP without sacrificing durability.
Cutter Blocks: 3D Innovations for the Best Performance
From the AxeBlock torque-reducing ridged diamond element cutter block to stabilizer blocks, our industry-leading family of cutter blocks combine the best cutters with a dynamically stable design for the best performance in a variety of formations—all in a variety of BHA configurations.

The Rhino XS hydraulically expandable reamer ensures proper activation and reliable underreaming.
How It Works
The Rhino XS reamer is primarily used with RSSs. Reliable hydraulic actuation is provided by the Z-Drive reamer cutter block deployment system. When activated from an activation ball dropped at surface, the Z-Drive system pushes the cutter blocks upward and radially outward to the fully open position, facilitating rapid cutout and ensuring a full-gauge, concentric borehole. When pumping stops, the cutter blocks retract. Dependable retraction of the cutter blocks helps avoid stuck BHAs.
Cuttings evacuation
Integrated jet nozzles and flow paths improve evacuation of cuttings while drilling. The reamer enables full flow through the BHA in both open and closed positions.
