20K Ultrasonic Driller/ Ultrasonic Corer (USDC)
The Ultrasonic/Sonic Driller/Corer (USDC) is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the material. A prototype of the drill was first released by NASA in April 2000, which weighed 1.5 lb. (.7 kg) and had the capacity to drill half-inch holes into granite using only 10 watts of power, whereas the modern household half-inch drill requires 750 watts. The USDC was originally designed to be able to drill through very rigid rock surfaces that would otherwise be damaged by a rotary drill, but has also shown potential usefulness to the field of medicine. It is the specific characteristics of the drill that make it ideal or practical for certain situations.
