In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.

A typical hole cutter drill bit consists of a circular blade with teeth on the perimeter, a pilot drill bit at the center, and often a shank that connects it to the drill. The pilot bit helps guide the hole cutter, ensuring a straight and accurate cut, while the sharp teeth on the circumference do the actual cutting. The design allows for faster removal of material, reducing the time and effort required compared to other drilling methods.

The evolution of thread drill bits mirrors the broader trajectory of technological progress in manufacturing. From hand-cut threads to automated machines equipped with advanced drill bits, the journey has been one of innovation and refinement. Today, with the advent of computer numerical control (CNC) technology, thread drill bits have become even more precise and efficient, capable of producing complex threads with minimal human intervention.
