Roller Reamer is designed for various reaming operation, but particularly for stabilization purposes when drilling in very abrasive formations. It will fit hole sizes ranging from 6"to 28".In addition, each body by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.
Huaxin develops and produces Roller Reamers with oil pressure sealing. Its simple and reliable structures make its service life longer, which can be used at least 200 hours. In the actual working, it can reduce horizontal vibration when drilling accordingly improving drilling efficiency and decrease frictional resistance and torque to enhance the wall quality.
Three different types (T,F and B) of cutters are offered:
Type T: Milled, machined with hardfaced sharp teeth for soft formations.
Type F: Milled, machined with hardfaced flat teeth, for medium hard formations.
Type B: Equipped with pressed-in tungsten carbide buttons, for hard formations.
