Pdc drill bit

We are offering pdc drill bits:
new products with super long life, high efficiency and wide application.
1) super long life-as 10 times as cemented carbide drill bits under the same condition.
2) high efficiency-times of lifting the drilling machine could be reduced sharply, and the average time efficiency could be increased more than 2 times.
3) wide range of application-it could have a penetration of rock formation with f ≤12,especially for the rock formation with f=5-10.
1. Pdc drill bits (non-core bits)
application for penetration of gas hole, water-discharging hole, and grout hole under coal mine.
size: dia 48-dia 270mm
