DTH Drilling Tools

According to different places of use, down-the-hole drilling rigs can be divided
into two categories: downhole and open-pit. Downhole drilling rigs can be divided
into self-propelled and non-self-propelled according to whether there is a
walking mechanism. There are many open-air down-the-hole drilling rigs in China,
most of which are self-propelled. 2. According to the different diameters, down-
the-hole drilling rigs can be divided into light-duty down-the-hole drilling rigs
(aperture of 80~100mm) and medium-sized down-the-hole drilling rigs (aperture of
130~180mm) Heavy-duty down-the-hole drill (aperture 180~250mm)
