Roller Reamer

Roller reamer, also called drilling reamer, is very useful tool for drilling operation, especially used for the function of stabilization in drilling of the abrasive formation.

The Roller Reamer is an efficient Bottom Hole Assembly (BHA) reaming and torque reducing tool. It provides reaming action for improved borehole shape, size and quality. It also provides stabilization action by centralizing the BHA, minimizing down-hole vibrations, preventing the BHA from resting on the low side of the deviated hole, and minimizing BHA fatigue.

Roller Reamers are designed for reaming and stabilization in any type of formation. TOSI can manufature any size holes' roller. All parts of the tools are made of special alloy steel and heat treated for hardness.

Three types of rollers are available here for reamer body:

Type T: Narrow tooth is machined and surface hardened, which is used for cutting of hole wall, used for soft formation.

Type F: Wide flat tooth is machined and surface hardened, which is used for cutting and crushing of hole wall, used for medium hard formation.

Type B: The roller is cold inserted with tungsten carbide string and used for hard formation.
