One of the most versatile tools in current use is the MHD5, known for its robust power class of 20 kW. This unit is designed for larger reaming diameters, reaching up to 127 mm, making it ideal for substantial rock clearance. For those requiring a more compact solution, the MHD100X offers a lightweight alternative at 53 kg, perfect for smaller drill holes between 22–45 mm without sacrificing the impact force needed for hard strata.
Furthermore, the HLX5 remains a staple in heavy-duty sectors, providing high penetration rates that directly correlate to reduced project timelines. When managing an underground hydraulic drifter, operators must prioritize the percussion rate and pressure levels. The MHD106, for instance, operates at a percussion pressure of 100–180 bar, ensuring that energy transfer to the drill bit is maximized while minimizing internal wear. By selecting equipment that offers a wide range of hole diameters and power classes, mining sites can ensure they remain competitive and efficient.
