Another benefit of a long flexible drill bit extension is its length. These extensions can vary in length, but typically they are designed to reach depths that standard drill bits cannot. This is particularly useful when working on projects that require drilling through walls or reaching into tight spaces This is particularly useful when working on projects that require drilling through walls or reaching into tight spaceslong This is particularly useful when working on projects that require drilling through walls or reaching into tight spaces This is particularly useful when working on projects that require drilling through walls or reaching into tight spaceslonglong flexible drill bit extension. The added length of the extension allows you to drill deeper and further than you could with a regular 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.
