WATCH: Metal Disintegration Machine vs. snapped-off tool part stuck in cast iron

In this video, a broken tap is removed from a heavy cast-iron machine part: "A Metal Disintegration Machine (MDM) or Electric Discharge Machine (EDM) was used to successfully disintegrate the broken tap saving the customer thousands of dollars. The broken tap didn't have a chance!" [via]

If you just want to see the magic spell being cast, jump to 5m in.
