Review on Tungsten Carbide Polishing Engraving Drilling by Richard Payne

This set surprised me. It turned out better than I expected. I only wanted 1 or 2 of the set but had to buy a set to get the ones I wanted. So I got them, I tried them and they are really good. I used them to modify the plastic frame. My next project is making a mold to glue/repair a broken binocular (instead of the eyepiece holder). buy them again. Beware, sometimes Chinese products are "modified" so they may be different now. I bought them on April 23, 2020 for $13.19.
