Great bits nice assortment

These work great I am still learning using my CNC but these bits are awesome.

This is an interesting kit. After receiving it is more clear what each set of bits actually are. I have doubts that I'll use most of them, but I guess good to have some of them in case they do become useful

Products are good quality at a good price

These are not 1/8 inch shafts, they are 7/64 inch shafts. (2.9mm instead of 3.17mm). The bit diameters are also off, by about the same amount. Some bits that are supposed to be the same are off by 0.5mm from each other. The picture included is supposed to 2 of the same bit, they are not the same size. The manufacturer data available for download and import into Gwizard and Fusion360 has the incorrect measurements as well. It also includes a LOT of bits that are not in the package, so you have to sort through a bunch of mislabeled bits in order to find the bits that you purchased, and they're still not correct. Although these measurements are very small, and may bot be a big issue for some projects, they can really mess up detail work, and with how small some of these bits are, they could ONLY be used for detail work. I will be trying requesting a refund. EDIT: the seller reached out and offered a refund. They were understanding, prompt, and professional.

They work great so far

A big variety of bits to try. I was able The bits work great.
