The HR head design will improve the engraving quality of a thunder laser cutter to the same standard as the famous laser brands from USA. And this installing is quite easy. Just unplug the air assist and unscrew the standard laser head.

Then replace it with the HR head. Just a few minutes, then you will get a totally different engraving quality! Amazing, right?
