We are joined by master jeweler Jeffrey Appling to discuss ultrasonic technology in the use of cutting and shaping stone. Jeffrey has been using an ultrasonic drilling and coring machine to cut, drill, and shape even the hardest of stones and jewels with ease. The bit of the machine does not spin, the ultrasonic vibration simply allows the bit to sink into the stone, so it is possible to core out shapes that are more complex than a simple circle, and do it in minutes with relatively little work.
