Medium and low wind pressure DTH bits
Advantages of HFD dive drilling
The drill bit is made of alloy material, which has a longer service life and is higher than similar products, and the drill bit crushes the rock by impact and shear. HFD drill bits have strong wear resistance and are suitable for drilling in soft and hard(9-grade drillability of rock,hard rock drilling) , compared with normal bit, especially for drilling 6-8 grade rock the effect is particularly significant.
