ROLLER REAMER

Roller Reamer is used for straight and directional drilling applications, when reaming and side wall cutting action is necessary and/or for point stabilization purposes when drilling in very abrasive formations near the bit or further up in the drill string.

All parts of the tools are made of special alloy steel and heat treated for hardness. Each body by simply adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes. As formations and/or drilling requirements change, cutters can easily be replaced any part at rig site without the use of welding,cutting or special tools.

Three types of cutters for different type of formation is available:

> Type T: Soft formation
> Type F: Medium to hard formation
> Type B: Hard formation

Type T	Type F	Type B
