Generally, the bit depth for rotary bits is within 50-60m and the bit diameter is within 2m. Most domestic reverse circulation bits within 1.8m have a bit depth of 100m and a bit diameter of 3m. It's almost impossible to do that with a rotating bit. This is determined by the structure of the bit. When the hole depth increases, a longer bit must be used. The extension of the bit will inevitably increase the weight of the bit. Therefore, taking into account the balance of the whole machine, the cost of the equipment will increase. In addition, if the drilling is too deep, the drilling time will be much lower than the auxiliary time of drilling, unloading, and so on, thus greatly reducing the work efficiency. The bit depth and diameter of rotary bit have no advantages over the circular bit, but they have absolute advantages in terms of working performance, environmental protection, displacement, especially formation adaptability, which can solve the most common problems in basic engineering.
