The single roller bit is used as an accessory, which is installed on the barrel drill alternately. It is mainly used in the pile foundation construction of municipal bridges and buildings, and is mostly used in coastal areas.

The rock-breaking principle of the rotary barrel drill is to form a broken ring by alternating inner and outer roller bit, then break rocks through extrusion, shearing and impact. Finally, break the rock core in the middle of the barrel bit by oscillating the barrel bit, and form the holes required for the construction after the rock core is taken out.
