A superior Roller Reamer

Reservoir Group have developed a superior Roller Reamer to provide enhanced run life with a unique and robust retention mechanism, allowing dependable reliability. An innovative stationary pressure equalisation system ensures that the seals within each roller cartridge, and the sealed journal bearing they protect, enjoy a greatly extended life, complimenting the premium grade carbide that retains full gauge.

Two important advantages

More Info

The WedgeTail™ Roller Reamer has two important advantages. High-grade specialized steel and an innovative stationary pressure equalization component developed by Reservoir Group giving the cutters an extended life, while the patented Taloc™ locking mechanism in the WedgeTail™ Roller Reamer means that cutters can be safely replaced in as little as 30 minutes.

Main purpose

More Info

The Roller Reamers’ main purpose purpose is to smooth the wall finish, maintain full gauge hole size, improve bit performance and bit life, reduce torque and vibration, and to ream out dog legs, key seats and ledges. The WedgeTail™ provides this and much more. 

Simple usage

More Info

 The WedgeTail™ is simple to redress, easy to maintain, and has never cracked in the pocket due to its design; historically, the Roller Reamers major problem over the past 15-20 years.

The patented ‘Taloc®’ locking mechanism 

The patented ‘Taloc®’ locking mechanism utilises two opposing tapered conical wedges, which focus the locking forces along the body of the tool. This allows a narrower pocket, for increased Flow-By area, but creates much higher locking forces that ensure full roller retention; yet the simple design facilitates safe cartridge replacement in a matter of minutes. The longitudinal locking mechanism also places less stress on the radial pocket design, and XDT® have never had a WedgeTail crack in the pocket…ever!

Features & Benefits
  • One piece roller cartridge for ease of maintenance, safety and security
    Self locating, self orientating to a truly neutral alignment
    No residual stresses prior, during or after dressing
    Extremely easy to maintain
  • Unique longitudinal locking mechanism: stronger retention, narrower pockets
    Greater fl ow-by area
  • Shorter upset length
    Reduced hole choking
  • Greater carbide efficiency – carbide positioned in helical pattern around cutters
    Constant 3 point wall contact, for better surface finish on hole
  • Bi-directional rollers as standard
    Allow constant back reaming
    Allow 90% of premium carbide to be placed on gauge diameter
    Ensure forces are transmitted equally over the centre of bearing shaft
  • Advanced stationary pressure equalisation
    No moving parts ensure 100% reliability
  • Stress relieved body profile to enhance flushing and cooling of cutters
    Allows body fl ex, for reduced fatigue
    Allows communication of fl ow-by areas
  • High temperature rating of seals and grease to 220°C
