Description

Introduction Hunan Feiray has developed a new kind of PDC pick, and it has got several patents. The tip of this kind of pick uses PDC insert instead of CARBIDE insert. Around the tip, the pick has CARBIDE inserts to make the gauge protection. This kind of PDC pick has excellent wear-ability and gauge protection, and it has a long useful life. Usually, its useful life is 6 times up than the CARBIDE pick. This kind of pick can reduce the replacing frequency, improve the development efficiency, and it can be widely used for mining. Testing We use the pick of U**5 to test the development machine EBZ**0C, the rock strata is limestone(with little quartz), the hardness class is 7~8. After **6 working hours, the useful life of the PDC pick is 6 times up than the CARBIDE pick. Parameter Table Hunan Feiray is a manufacturer of PDC tools, we can produce the PDC picks of U*6. U*2. U*4. U*5. U*2. U*4. U*5. U**5. U**0 and so on, the detail is as follows: (We can also make the PDC picks according to your drawings.)
