There is no fixed tooth shape and bearing for the hole opener bit, so it is necessary to select appropriate tooth shape and bearing structure according to different stratum structure. It adopts the palm back tilt, cold inlaid anti - ruin gold design, with the roller anti-peeling structure, mainly to prevent the roller falling off after the roller bearing is damaged, resulting in the accident in the hole. The hdd rock reamer is suitable for horizontal directional drilling construction, with high design strength, good wear resistance, long service life and good safety performance. The reaming size is 220~1600mm.
