The design of a thread drill bit is a marvel of engineering. Its point angle and flute design are optimized for chip removal, ensuring a clean hole while preventing the bit from jamming or clogging. The cutting edges are precisely ground to produce the desired thread pattern when the drill bit is run through a material at the appropriate speed and feed rate. The result is a thread that is accurate, consistent, and ready for immediate use without additional finishing processes.

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.
