The brief description of PDC drilling bits.
PDC drilling bits are one of the most popular drilling tools for a borehole drilling rig, this kind of drilling bit can be a steel body PDC drilling bit or matrix body PDC drilling bit. The full name of the PDC drilling bits is called polycrystalline diamond compact drilling bits and most of the time this PDC drilling bit is used for drilling an oil well but sometimes it can be used for drilling a water well borehole too. The cutting blades fixed on the cutting head of PDC drilling bits are called polycrystalline diamond compact, and that is why it is called PDC drilling bits.
The specifications of PDC drilling bits.
- PDC Polycrystalline diamond compact drilling bits are used for oil fields or for drilling a water well.
- The fixed cutter on the blade wings makes the PDC drilling bit more durable while drilling a water well borehole.
- The nozzles on the cutting head control the water follow.
