Processing Customized Coal Mining And Drilling Hole Diameter JM
Cone Roller Drill Bits
Describe
It is important to understand the type of formation to be drilled
when selecting a drill bit. The TCI melamine cutting head in the
middle layer has corrosive tungsten carbide cutting blades in the
heel row and inner row. This design provides fast drilling speed
and increases the durability of cutting structures with medium to
medium hardness. HSN rubber O-rings provide sufficient sealing for
bearing durability.
