2. Drill bit shank - Wikipedia

   en.wikipedia.org/wiki/Drill_bit_shank

   The SDS bit was developed by Bosch in 1975 improving on the TE system introduced by Hilti in 1960. Hilti's original 10 mm TE-D and 18 mm TE-F shanks can be used in SDS-plus and SDS-max chucks respectively but not vice versa while the newer TE-C, TE-T and TE-Y are fully compatible. The SDS name is an acronym of German: Steck – Dreh – Sitzt!

   The connection end size is also related to the breaking energy of the tool. For example, the Bosch and Hilti 12 lb (5.4 kg) tools both use SDS-max, while the Bosch, Hilti, and Makita 65 lb (29 kg) tools all use 1+1/8 in hex connection. See hammer drills for more on electropneumatic hammering.

7. Bernoulli grip - Wikipedia

   en.wikipedia.org/wiki/Bernoulli_grip

   The flow of air causes a lifting force on the object, allowing for non-contact adhesion. A Bernoulli grip uses airflow to adhere to an object without physical contact. [1] ...
