HDD Rock Reamer An HDD Rock Rea mer is one of the most versatile tools for drilling holes in HDD drives. It can be used to open up six-inch holes, as well as larger sized ones. These tools have a wide range of applications in oil well drilling. A 600mm HDD Rock Reamer comes with five pieces of 81/2" 217 cutters. A variety of different sizes and cutting structures is available for different applications. An HDD Rock Rea mer is also called a Horizontal Hole Opener. It is used to drill a pipe of varying diameters. It is not used on very small pipes, which are too thin to drill with. Once the drill hea d is removed, a larger tool is attached to the drill string. Back reaming is a process that s mooths out the borehole walls, reducing the risk of voids or settlement. Using a HDD Reamer in this way helps prepare the borehole for the product pipe. An HDD Rock Rea mer costs $250 to 15500. A standard model can reach up to a diameter of 12 inches. They can be used for a ny size of pipe, depending on the diameter. Once the drill head is removed, the larger tool is attached to the drill string and can be used to open pipes of different dia meters.
