The description of a diamond PDC rock drag drill bit.
A diamond PDC rock drag drill bit, a simple and durable drill bit for drilling a water well borehole, is also called a PDC drag drill bit. In the market, there are three wings of Diamond PDC rock drill bit and four wings of Diamond PDC rock drill bit. This PDC drag drill bit needs a mud pump to work, the water will be injected into the water well borehole to cool down the diamond PDC rock drag drill bit and wash the cuts out of the water well borehole.
