Composite bit is also called polycrystalline diamond composite bit
At first, composite bits could only be used in soft shale
formations because hard interbeds could damage the bit. However,
due to the emergence of new technology and structural changes, the
composite bit has been able to drill hard interlayer and long hard
rock formation.
Composite bits are more and more used by people, especially with
the continuous improvement of the quality of the composite bits.
Now, the composite chip bit products can be used in areas that
could not be used before, such as harder, more abrasive and
variable formations. This expansion to the new field has a great
impact on the balance between diamond (fixed cutting teeth) bit and
cone bit.
Composite bit is suitable for soft to medium hard rock strata. Now
some new composite chips developed by some manufacturers can be
applied to rocks with grade 10 hardness. More and more composite
bits are used in domestic coal mining.
Quartzite, basalt, solid granite, quartz porphyry, firm
conglomerate, strong sandstone, limestone, etc. can be used
