Used this to make a detent notch in an AK brake (AK detents are 4mm) that didn’t have one. It cut through the nitriding (60-70 HRC) and left a great surface finish on the underlying 17-4PH. After cutting a few notches its still very sharp and has a lot of life left.

Quality product at a reasonable price. Next day delivery and as advertised. Mill cuts well in a tough material and is showing no signs of wear after making several parts.

For some reason, I thought this was a 1/8" end mill I could use in my Dremel. It's a little big for the Dremel, so I'll have to get a bigger chuck. Seems like a nice bit!

Endmill cut through a hardened steel like a champ. Cut a keyway 6" long in 45-50 HRc chrome steel. Looks brand new still.

Only using for plastic but for the price a very clean cut if you watch your feed rates.

Used it to mill plastic and recently experimented with aluminum to see how it’d do. Both materials cut easily and stayed sharp
