They are fitted with Digga / Eaton bell motors with integrated pressure relief valve and input housing. The innovative design allows the gearbox to go down the hole to maximise drilling depth without extensions, eliminating downtime and minimises maintenance, optimising your returns. Digga planetary auger drives are specially designed for drilling and augering in most ground conditions.
