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.

The hard carbon aerogel can maintain the super-elasticity in harsh conditions, such as in liquid nitrogen. Based on the fascinating mechanical properties, this hard carbon aerogel has promise in the application of stress sensors with high stability and wide detective range (50 KPa), as well as stretchable or bendable conductors. This approach holds promise to be extended to make other non-carbon based composite nanofibers and provides a promising way of transforming rigid materials into elastic or flexible materials by designing the nanofibrous microstructures.
