Their operation is straightforward as well. They are commonly used with a drill press for accuracy and stability, but can also be employed with a hand drill, albeit with less precision. The central point guides the bit while the flat edges cut away the material. However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonry However, due to their size and design, they are not suitable for drilling into harder materials like metal or masonryflat drill bit.

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.
