Inventors at the Tel Aviv University have developed a microwave drill that can bore through concrete or glass without major problems. The technology works by preheating the material to be drilled by using microwaves. The material can reach the 2000 degrees Celsius, and then the drill can work without dust, noise or major delays. The drill bit emits intense microwave radiation creating a hot spot around the bit, melting or softening the material so that the bit can be pushed in.
One of the main advantages of this microwave drill is the cost. Despite heat is not a new idea to enhance drilling, Laser drilling is too expensive hence the microwave drill became a cheap alternative to industrial use.
