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.

The concept of gas rock drilling, commonly associated with hydraulic fracturing or 'fracking,' has revolutionized the global energy landscape. It involves the use of specialized drills that can penetrate hard, impermeable rock layers such as shale, sandstone, and coal seams. These rocks, often rich in hydrocarbons, have long been considered inaccessible due to their tight structure. However, with advanced drilling techniques, they now hold immense potential as energy sources.
