All endmills are excellent quality and delivered before they were due.

Great endmills and a great price. I use them on hardened tool steel and had no issues.

Bought these for a hobby. Received them and like that they are packaged individually, thus helping keep them sharp. Used them on a firearm building project and only eneded up using one. But stayed sharp and met the needs of what I was using it for. If your are a hobbyist and looking for some high quality milling bits with out having to pay a premium these are the ones to go to.

they are a bit brittle. If the cutting head moves (shudders) they will chip.

Held up very well cutting 304 stainless even under sub-optimal feeds and speeds, which were the limitations of my CNC. I tried another (different brand) popular carbide end mill on the same job / stock subsequently for comparison. The other end mill ground itself into a needle due to intense heat. But this Speed Tiger came out of the same job intact and still sharp.

I wasn't expecting to much out of these end mills due to the price. Let me tell you these .25 end mills are worth more. I used 1 endmill and ran it nonstop on my Bridgeport for 9 hours straight. After the piece was completed I checked the endmill and it was as when I first put the endmill in. I will be buying A LOT more of this brand. Now to test their .375 roughing bit tomorrow.Update: These end mills are way better then I ever gave them credit for. I had to make a few die molds for our production line. Material was 4140 for the tie downs and D2 for the actual dies. I was able to cnc mill everything with a single end mill. I used only air to cool the work piece and clear the path.

The design is a good one, but the execution is superb. I got the pkg. of five ⅛ in bits. I immediately tested it on the door latch for my new front door dead bolt. The strike plate already there meets the highest safety standard, which is done by the use of certain steels, their thickness, and the means by which they're attached to the door frame.The problem turned out to be that it was slightly off and it got in the way of the bolt extending. I spent a half-hour hand filing that thing to get it to work. When the bits arrived, I decided to see if I could use my Dremel tool with this bit to even everything off. Wow! What a great purchase. After juxtaposing the hand filing with the use of the bit, separated by less than 24 hrs, I'll never forget I have it when it can be useful and I know I'm going to be glad I do. This is a piece that is overkill for us mere mortals. It's meant for CNC gods.

UPDATE: I upped my rating from 2 tp 4 stars. Customer service was very helpful and responsive. They actually contacted me when they saw my original review. I found that my spindle speed was too slow. Obviously it depends on the material but these bits have to be spun pretty fast and the depth and feed rate must be shallow and slow as well. My mill only spins at max 2800rpm. So I spun it at 2800rpm and took a more shallow cut along with a slow feed rate and these things cut pretty decently. I assume they would work better at an even faster spindle speed. They are still very brittle and will snap if you apply to much side pressure. Overall they did the job I needed them for.Item came packaged well and they looked good. I ordered the 1/16th size and these things snap at the slightest pressure. I almost messed up my project so I had to discontinue using them due to them snapping so easily. I tried another set I had and had no issue.
