Product Description

The Roller reamer is designed for any reaming operation and particularly for stabilization purposes when drilling in abrasive formations. According to the different hardnesses of formations,you may separately select sharp-fanged roller,wide-fanged roller or tungsten carbide compacts roller. In addition, each body, by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes. 

MDX Roller Reamers have a heavy duty design based on a wide range of operating experience. They can drill in any condition, be it soft, medium or hard formations. The reamers are built to maintain the necessary hole gauge when drilling straight or deviated holes. They consist of cutter, bearing pin, cross pin, lower block, upper block, secondary locking bolt.
