MOON GLOW DOTS appear to be laser cut, with very precise diameters. All 50 of the 1/4" dots I purchased fit perfectly in counterbored holes cut using a 1/4" brad-tipped bit. After gluing the dots in place, I used standard sand paper (180 to 600 grit) and a light buff to finish the pieces. Sanding works well, but don't use HHS cutting tools on this material, as it will dull your tools to a pitifully blunt hunk of steel in a micro-moment. With that one qualification, I like these easy to use and very attractive dots a lot.
