A portable magnetic drilling machine is faster and more portable alternative to hole making machines such as the drill press, and is more accurate than a hand drill. A portable magnetic drilling machine is used on steel or other magnetic materials. It gives an accuracy of 0.01 mm to 0.05mm in steel or other magnetic material.
The Schramm T685 WS truck mounted drill bored a 5.5 inches (14 cm) hole that, on 22 August 2010, was the first to break through to the 33 trapped men, confirming they had survived the accident.
