In the mining sector, rock drills play a pivotal role in the extraction process. They are used for both surface and underground drilling, facilitating the creation of blast holes for explosives. The precision and speed of these drills significantly enhance productivity, reducing overall operational costs and increasing efficiency. Their ability to drill deep into the earth's crust allows access to previously unreachable mineral deposits, thereby expanding the scope of mining operations.

A taper bit's unique design sets it apart from conventional drill bits. It features a gradually narrowing cutting edge, which allows for a smooth transition from a larger diameter at the base to a smaller one at the tip. This gradient can range from a subtle angle for furniture legs to more dramatic tapers for musical instruments like guitar necks. The percentage indicated as 'taper%' refers to the rate at which the bit tapers, usually measured over a specific length.

Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
