Jiayou sincerely appeared at the exhibition with APFXKSYS-S2 cylinder bottom drill bit:

       Construction method: The square head is connected with the rotary drill pipe. The bottom drill bit is sent to the bottom of the formed hole. The drill pipe is pressed down and slowly rotated, so that the reaming wing is slowly opened to the design size and reamed. Operation, when it is fully opened, quickly expand the reaming hole and clear the slag without pressing it in place. After a certain period of time, raise the drill bit at a uniform speed (at this time, continue to rotate). After the reaming wing is completely contracted, stop rotating and raise it When the bit reaches the ground, press the bit down with the pressure plate, the bottom plate of the upper pressure drill pipe is opened, and the rock powder is poured out.
