4.Feature
Compared with tungsten carbide, PDC roof drill bit has the following advantages:
The PDC roof drill bit has a service life of 85-300m in the drilling of rock hardness f= 4~8, while the average footage of the tungsten carbide roof drill bit is 4.5m, the difference between the two materials are dozens of times.
