Pdc Core Bit - 75mm Outer Dia, 53mm Inner Dia, 150mm Height | Super Long Life, High Drilling Speed, Low Pressure Operation, Good Gage Protection, Cost-effective For Geological Exploration

Features of Drill Bit:
1. It has a super long life. The grinding/consumption ratio of
PDC is 20-40 times that of tungsten carbide bit and 10 times
that of diamond bit.
2. It had high drilling speed.
3. It can be operated with low pressure and low speed.
4. It has a good gage protection.
5. It can be used widely, more suitable for drilling in the
stratum with formation
6. It has a low cost
