The description of a water well borehole PDC drag drill bit.
A water well borehole PDC drag drill bit, a type of fixed head drill bit, is used for drilling a water well borehole, and it is now one of the most popular drill tools for a water well driller in the market. A drag drill bit is called a water well borehole PDC drag drill bit because the cutting head is made of polycrystalline diamond compact and most buyers use this drag drill bit to drill a water well borehole. There are four cutting blades PDC drag drill bit and three cutting blades PDC drag drill bit in the manufacturer, the buyer can choose according to the requirements.

- Normal Diamond PDC drag drill bit can drill F＜10 soft middle hard rock layer
- Reinforced diamond PDC drag drill bit can drill F=10-12 middle hard rock layer
- High reinforcement diamond PDC drag drill bit can drill F＜18 rock layer.
- The diameter of the diamond PDC drag drill bit can be customized according to the requirements.
The features of a water well borehole PDC drag drill bit.
- The service life of the water well borehole PDC drag drill bit is long and able to drill through complex rock formations in the earth.
- The high hardness of the diamond cutter makes the water well borehole PDC drag drill bit more durable and more efficient when drilling through rocks.
- The special design of the cutting blades cuts the rocks evenly and the big gaps between the cutting blades improve the drilling speed.
- The structure of a water well borehole PDC drag drill bit is simple and the price is cheaper also.
The usage of a water well borehole PDC drag drill bit.
The water well borehole PDC drag drill bit can be used for engineering drilling rig equipment, such as water well borehole drilling rig equipment, hydraulic drilling rig equipment, core drilling rig, etc. It is can be used for drilling an oil borehole, geological exploration, the building of a railway, and building a tunnel.
