A new technology developed at Tel Aviv University will make the process of drilling through glass and concrete easier and cleaner.
By using microwaves to heat a material to over 2,000 degrees Celsius, it softens it up enough for a rod to be pushed through. In addition to dust-free concrete drilling, the tech is also effective in putting holes in glass without breaking it, not to mention being a pretty sweet upgrade to your standard power drill. The microwave drill can make holes between a millimeter and a centimeter wide, and is significantly cheaper than laser-drilling alternatives. Just be careful to keep the concrete-melting microwave beam away from any body parts you’d like to keep functioning.
