Review on ⚙️ High-Precision HUHAO Spiral Degree Engraving Aluminum: Stellar Quality and Precision for Engraving Projects by Lawrence Crespo

Under the microscope they looked fine at first - some cut edges were chipped but high enough for a 0.005 engraving to be ok. But after doing the job with conservative settings I see that they are pretty terrible. I get better results in bronze, copper, and silver with standard circuit board cutters that are half the price. They may be suitable for softer materials but overall I was very disappointed in them.
