The gear box is made by ourselves with high precision, low noise, less worn out so have a long service life. Rock bit is like cone shape, with sharp rock teeth, it has strong drilling and it 's easy to dig into the ground, suitable for some hard soil, such as frozen soil and hard soil. For the tungsten bit, it is like a fish tail shape, and the tungsten teeth are flat, and easy to move earth. It is suitable for some relatively soft soil, such as loess, clay, backfill and so on.
