I'm using it to drill out carburetor jets, so precision isn't so important as each bit being slightly larger than the last, and this set does not seem to do that. I get one that is a tight fit, and the next three are identically tight fits.The problems are the accessories. The case holding the bits starts out as nearly impossible to slide, I had to remove the top and shave the bump down a bit(clear plastic in picture, the bump is to the right of the brass piece).For the actual holder, it includes a brass piece with two slots to allow it to expand to hold the drill bit, with a collar clamp to tighten things up. The problem with this is that the brass piece(pictured with one of the bigger drill bits there), is still too narrow to get the drill bits in there even doing some widening with a razor blade(because not much else is thin enough to fit in there). The slots are also visibly off center.

I should have read the reviews on this one. The drill bit set was a good value for the money. However, the pin vise was not. The mandrel in the pin vise was not centered like many of the other reviews on here, so it is basically useless.

Quality is so-so. As an hobbyist, this will be fine for occasional use. There's enough drill bits to make it through most any project. At the price I am ok if the kit has limited use.

Love this product used it way more than iv expected I purchased a carb for my custom motorcycle and I got a jet kit and it still didn’t get enough fuel so instead of buyin more jet kits I got these and drill my own with the spare jets I have from the kits I already have and it works so great for brass jets haven’t had one issue no breaks no dullness no nothing they are very small so be careful they can only be made so strong at there size they are tiny case works great seems durable I would recommend 10/10
