Thirty tons of burrowing, tearing might, powered by a nuclear reactor – that's the Mole, the amazing drilling machine invented by Brains. The Mole has brought succes to many rescue operations where trapped disaster victims would have perished if it had not been for this machine.
A tracked trolley carries the machine to the drill site where it is tilted for vertical drilling with its Formula C30/1 drill bit which can cut through any known metal. Caterpillar tracks on its side allow for its return to the surface when the rescue is complete.
