    en.wikipedia.org/wiki/18650_battery

    An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.

    en.wikipedia.org/wiki/Lithium_polymer_battery

    A lithium polymer battery, or more correctly, lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly, and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Highly conductive semisolid polymers form this electrolyte.

    A hand-held corded electric drill A lightweight magnetic-mount drill. A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver chuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use.

  6. Drill bit shank - Wikipedia

    en.wikipedia.org/wiki/Drill_bit_shank

    Large drill bits can have straight shanks narrower than the drill diameter so that they can be fitted in chucks not able to chuck the full diameter. Such a drill bit is called a reduced-shank or blacksmith's drill. For example, this allows a 1 ⁄ 2-inch (13 mm) bit to be used in a pistol-grip drill's 3 ⁄ 8-inch (9.5 mm) chuck.

  7. Deep reactive-ion etching - Wikipedia

    en.wikipedia.org/wiki/Deep_reactive-ion_etching

    This is known as the chemical part of the reactive ion etching. There is also a physical part, if ions have enough energy, they can knock atoms out of the material to be etched without chemical reaction. There are two main technologies for high-rate DRIE: cryogenic and Bosch, although the Bosch process is the only recognised production technique.
