Gone are the days when drilling concrete was a dusty and noisy buisness because microwave drilling has been successfully demonstrated. These microwave drill soften and heat the material to 2000 ºC using microwaves and a rod of required size is pushed through the material. The drill bit is a needle-like antenna that emits intense microwave radiation. The microwaves create a hot spot around the bit, melting or softening the material so that the bit can be pushed in.
The main advantage of this drilling technology is:
- Noiseless operation.
- No dust is produced in the operation.
- Lower cost of operation when compared to the expensive laser drilling
Materials like concrete and glass can be used with this drill.
