- 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

Narrow opening grating also means that tools are less likely to fall through the grating if the operator drops them while maintaining the site.
This also adds to how flexible FRP grating is, as its lightweight nature makes it flexible and easy to cut. Because of this, it is simple to customize this grating to fit the project.




In the future, the joint laboratory will also develop a variety of high-performance lightweight composite products and technologies, serving the automotive, aerospace, industrial machinery and other industries.
