About This Product
When introduced in 1993, it was the largest model capable of reaming with a maximum diameter of 4750 mm. In order to take advantage of the high power of Bigman BM600A, we have developed a φ6m reaming bit. He is still active in various fields.
■Basic procedures for reaming and digging
A Big Man is installed on the bedrock above the shaft, and a thin vertical shaft is usually dug toward the shaft to pass the Big Man's special rod. This is called pilot digging. After penetrating the lower shaft, remove the pilot drilling bit that has penetrated and connect it to the reaming bit installed in the shaft. The large-diameter reaming bit is pulled up by a big man and excavated.
