One of the key advantages of FRP walkways is their non-slip surface. Regardless of weather conditions or exposure to oils and chemicals, the textured surface ensures optimal grip, thereby enhancing worker safety. Moreover, these walkways are resistant to corrosion, a trait particularly valuable in environments with exposure to harsh chemicals or saltwater. Unlike metal, FRP does not rust, making it suitable for marine applications or areas prone to dampness.

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.
