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.

High-quality stone drill bits are designed with durability in mind, as they are subjected to extreme conditions underground. They are typically made from materials such as tungsten carbide, which is known for its exceptional hardness and resistance to wear. This ensures that the bits can withstand the constant grinding and impact forces encountered during drilling, extending their lifespan and reducing the need for frequent replacements.
