Roller Reamers

Technical Summary

We manufacture, sell and rent Roller Reamers in 3 Point and 6 Point configurations. Another versatile downhole drilling component, Roller Reamers complement our broad range of downhole stabilization products. They can be used in straight and directional drilling applications when a side wall cutting action is necessary and/or for point stabilization near the bit or further up in the drill string.

Our Roller Reamers make the difference downhole when used to maintain hole gauge, wipe out key seats and smooth out rough and troublesome ledges which will cause the drill stem to stick and bind. Our Roller Reamers also help to reduce drill stem torque in highly deviated (horizontal) boreholes and can greatly assist the operator in maintaining drill stem stability.

You have the flexibility to use the style that suits your drilling needs best and provides you with the maximum reaming and side wall cutting action. Combining 3 or 6 point stabilization with reaming keeps the hole to size, the bit on track, and ensures smoother drilling operations.

  • Available in Soft, Medium, Hard and Smooth
  • Available in 3 Point and 6 Point configurations
  • Cutters can easily be replaced on rig floor

Heat treated and machined with precise dimensional control, our Roller Reamer parts are inspected in the pre- and post- manufacturing process phases and checked again for conformance to interchangeability needs and requirements.

Sealed Bearing Roller Reamer

Reacting to feedback from clients and in order to produce a more cost effective and longer lasting reamer, out technical department has modified the cutters currently used in the standard Model 60 reamer. Using the same body and decades long reliability of the tool we have placed O-rings at each end of the cutter to seal off the bearing section and that has allowed longer runs and greatly reduces wear and damage to the body. With the improved reliability of the sealed bearing cutter and using the compression fit blocks this has helped with side loading of the tool and also the high shock placed on the reamer during drilling. Adding the seals to the cutter has allowed us to extend tool life without the high cost associated with current sealed bearing reamers in the market place.
