- Tungsten carbide, an alloy composed primarily of tungsten and carbon, is renowned for its exceptional hardness and wear resistance. It is these properties that make it the ideal material for manufacturing mining button bits. The 'button' refers to the protruding segments of tungsten carbide that are brazed onto the drill bit, creating a robust cutting edge capable of withstanding the intense pressures and abrasive conditions encountered deep within the earth.
- The tapered drill string is characterized by its gradually reducing diameter from the top to the bottom. This reduction in size not only optimizes the weight distribution along the string but also enhances its flexibility, enabling it to navigate through challenging formations with ease. The smaller cross-section at the bottom end lessens the drag and torque, which is particularly beneficial in horizontal or directional drilling where friction can be a limiting factor.
- One of the key features of tunnel bench drilling bits is their durability. These bits are manufactured using high-quality materials that can withstand the extreme pressures and temperatures encountered during drilling. This durability ensures that the bits can effectively penetrate through tough rock formations without wearing out quickly.
two types of fiberglass grating (FRP): FRP Molded Grating and FRP Pultruded Grating.
