Twist drills, with their helical cutting edges, became the standard for 75mm drill bits in the 1960s. These drills cut by shearing the material and ejecting it through the flutes, resulting in cleaner holes with less material buildup. The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels The development of twist drills also led to the refinement of drill bit geometry, including the addition of secondary cutting edges and better chip evacuation channels75mm drill bit.

  • FRP ducts, primarily composed of glass fibers embedded in a polymer resin matrix, provide exceptional mechanical properties. The glass fibers lend tensile strength while the resin provides rigidity, making these ducts highly resistant to impact, wear, and tear. This resilience makes them ideal for use in harsh environments where exposure to chemicals, extreme temperatures, or corrosive substances is common.
  • Advances in technology have led to the development of more efficient and durable rock drilling tools. For example, the use of diamond-tipped drill bits has improved the speed and precision of drilling operations, while the development of automated drilling rigs has reduced the risk of human error and increased productivity.
