I definitely recommend these bits.They do a wonderful job for what they are -- inexpensive bits in a bulk size number. The small ones are a bit fragile as is to be expected -- make sure you're using an RPM and feed rate calculator and you know the specs of your machine to avoid damaging these. Obviously if you run your 1.0mm bit against a rather elevated rise of bloodwood at 2000mm/min, yeah, it's going to snap like a twig -- this is user error though, not manufacturer error.The quality of cut with these bits is superb. With the 2mm and a clever bit of g-code tweaking after spitting out my post process from Fusion 360, I was able to get tolerances on my model in the sub 0.05mm range on a bloodwood stock. I'm already planning to buy a whole second set, just to replace the 1.0mm and have extras -- can't argue with it for the price really.These don't really replace higher end bits. Don't expect to get away without buying the occasional necessary role-specific bit at significantly higher price points. But to get started, get good results, and have a wide selection, this set is a great choice.I do recommend though if you're going to buy one of these sets, go ahead and put the money down for two of them. This way if a size you need breaks, you have the spare right there. This is especially so if you're still learning your machine and relevant techniques.

Didn't look exactly like the pics with a gold portion so not sure I got exactly what I ordered but they got the job done well. Ground off portions of a steel PC case easily, no visible degradation on the bit afterwards.

Bought this set to replace a busted carbide Dremel burr for a project I had grinding steel. These replacement bits certainly did the job, and then some. The carbide Dremel burr broke on the first piece, these however literally stopped the tool when they got stuck. The bit looked unused when I finished. Good stuff.

Muy bueno. Los uso para tallar madera e higuera

Some have too much runout, they become hardly usable for fine work.

I’ve only used one of the bits from the kit so far but it has held up cutting slots into 20 pieces of 1/16” steel so far.

I liked its size I get All I need at one time but I always asked to do a review but I don't get anything for free to try like the people on YouTube

These 1/8 inch bits work better than I expected,for their price.
