Whenua's earthshock drills could bore through any substance known to Matoran.
Whenua could activate his earthshock drills to spin at high speed. They could bore through virtually any substance, even at low speed. However, they had another feature: when in use, they produced a loud hum. When spun fast enough, this hum went from painfully loud to ultrasonic, able to cause structures nearby to crack, although this put strain on Whenua himself too.
