How to choose a drill pipe? According to the actual situation, choose a suitable drill bit. If the geology is relatively hard, then the rig is relatively high. You must choose a drill rod that is as strong as possible and the drill bit is not so large. The idea is to choose a larger drill bit. The larger the bit, the larger the contact surface during drilling. The larger the drilling pressure under pressure, the more reasonable the bit should be. The bit should not be too large to meet the needs.
的 The hardness of the drill bit is the most important index to measure the quality of the drill bit. The higher the hardness of the drill bit, the easier it is to drill, but the more difficult it is. Therefore, we must choose a high-quality drill bit produced by a large company to ensure the drilling efficiency and the drilling efficiency.
