Drilling Diamond Bit PDC Drill Bit With Twin Wings
Product Description
Drilling drill bit/PDC roof drill bit/twin wings PDC drill bit widely used in all industries, such as coal mining, oil exploration, geological exploration, water and hydroelectric, railway and road, tunneling construction and so on.
Two-wing PDC anchor bits/twin wings PDC drill bit (semi-round standard type) is applied to the hardness not bigger than f8. The working life is 10-30 times of the ordinary alloy bits, and the efficiency could be improved by 60%. Besides, the PDC bits don't requires figuring, which lows the labour intensity and helps to saves cost.
