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.
