• MHD


    The MHD series delivers maximum productivity, fast set-up, quicker drill cycle times and a low operating cost through our customer-inspired designs and top of class power. Equipment life is long thanks to our completely hydraulic design and focus on using the highest quality components. This combination of the hydraulic design and easy maintenance means more hours of reliable, low-cost operation. The MHD series is available in standard mast or short mast configurations with either square bars or round, interlocking Kelly bars. We also offer both track and truck mounted versions.
