Review on Exquisite Polymer Jewelry Set in Assorted 0.1-1mm Random Pieces by Jarod Berthelson

The grip is fine for the most part, but the collet seems to be a bit off-center, making it a bit difficult to use. The biggest disappointment is the drills themselves. More than half of the standard nozzles have only one cut. They are essentially raw steel drills, not drills. If you need smaller sizes, buy something else as that includes all smaller sizes. I suspect these are more expensive to produce so they just added something to make the description technically "accurate". actually a drill, one. On the plus side, the packaging was quite nice. Lol Everything was organized, bits sorted into three packs and they came with a nice strong soft plastic PCB bit holder. All in a neatly sealed box. Although the circuit boards are fine. If you just want to save some money and buy them without add-ons or spend a few bucks more for a better set.
