This set is wrong. The 1/4 shank bits fit my 1/4 collet fine but the 1/8in shank bits are too big. You can see in the photos of the Chinese bit (.153in) compared to my American made (.12in) cnc bit. Another problem are the labels on the bit tubes, they are all in Chinese. I use bits like this daily so I can typically recognize what I need by sight but this is ridiculous. Also notice the photo where it appears that the coatings on the bits are totally different. One is dark where the other is kind of gold colored. The dark colored bits honestly just look like they have paint on them. You get what you pay for. These are going back. Very disappointing

I have a CNC machine shop and we machine 304 stainless all day long. These bits outperformed Accupro bits (admittedly, Accupro is a low cost provider) which cost $20-40 per bit at MSC. Comparing to performance endmills, these are clearly not as good (about 3/4), but performance endmills can easily cost $100 each. It's very hard for us to justify using a performance endmill when these perform so well at a tiny fraction of the price.

I've only had the end mills for a couple of weeks but so far they have been cutting very well they've cut on some hardened steel and some softer metals and have done quite well. I do wish they had a better storage case than the little plastic containers they come in but overall happy with the purchase. They are extremely sharp and holding their sharpness quite well. Have used them at low speed and higher speed with great success just be careful with the smaller sized end mills they seem to be decent quality but you still have a chance of breaking them as they are very thin you must go slow when you cut.

Pretty good for Chinese mill bits. Made cutting through Hardened 4150 steel feel like brass.
