Very tough and sharp.
I have used these to cut wood, plastic, aluminum, hardened steel, and stainless steel. So far they have worked very well and are still sharp as new. Haven’t burned up any of them yet. I like ‘em!!

Great little corn cobs
The 1/8 cob cut bits are monsters, Love 'em, wish I could buy them in a stand alone pack. I just sit like a cave man and watch them granulate steel. I've always thought that chips were the way to go but these little guys showed my something different. I thought that these were more for wood and such and only grabbed it off my shelf out of desperation but they cut well. I had to feed it a slow cutting speed (.001 or so per sec at 900 rpm) but it worked like a charm on 1045. I chewed one up after about an hour, but I had gotten a little impatient and dinged the very tip up. The flutes kept cutting! The price on these is good, like I said, just wish I could buy the 3mm in multi packs by themselves.

Update, to 4 stars
The smaller bits are not very durable. Seem to be brittle and prone to breakage. I thought at first it was just me pushing it to fast but reducing the the speed did not help. Update, Customer support supplied me with replacement bits and these are working much better.

Smaller bits are not durable
small bits lasted 1 pass then broke. I was even cutting MDF. I adjusted my feed rates and pass depths accordingly for the small bits. The larger bits do cut, but i feel they do not cut as cleanly as a standard spiral up or down bit. Price is cheap, so i gave them a shot, but i wont purchase these bits again and i have put them aside for now.

Actual dimensions are all over the place.
The largest is in fact very close to 3.175mm, and the smallest close to 1.5mm, but other than that they seem to be placed at random sizes, nowhere close to representing the dimensions shown in the photo. I also got two identical 2.4mm bits, which is not a huge deal for me, but I was consider using the 2.2mm for something and I didn't get one. So they're cheap and good for things that don't require a specific width dimension.

折れにくい。
結構タフで折れにくい。CNC3018で12ｍｍ厚のプラスチック（ポリアセタール）から切り抜くのに使っています。アルミはちょっと苦しい。鉄はやめた方がいいです。

Great quality but the sizes are not as advertized
These bits are great! However, my set didn't come with all the sizes listed in the description. The bits I received are 1.5, 1.6, 1.8 (x2), 2.0 (x2), 2.4 (x2), 3.175 (x2). Not a big deal for me, and I am happy with that assortment, having 2 bits of the most sizes. But be aware if it's important for you to have all the listed sizes.
