These bits cut well and seem to cut smoothly. I will update if I have any issues or life of them.

These 5 packs of carbide ball nose 1/4" shank/diameter CNC router bits were made for metals. They have an AlTiN coating to reduce friction and extend their bit life. The cutting edges are nicely formed, sharp, and consistent with the better bits in this price range. I am successfully using them on my CNC Sherline mill and 3030 Pro Max Genmitsu CNC router to mill aluminum. The shanks are marked with the bit’s specifications, and the bits come individually packaged.I am pleased with their performance and plan to order again.

Very sharp bits. They come well protected in very nice individual cases that are great for storage. These will be very handy for my woodworking projects and I will update if there are any concerns that arise later.

I have a mini-mill (cant recall if its a Sieg C3 or C4) but it weighs around 300 lbs... so a light weight in terms of mills.I use this in a er32 collet. The feeds/speeds vary depending on the material... so far wood, plastic, aluminum. It seems to be sharp and produces descent surface finish quality. I have not plunged it deep yet so I cant say how this will do roughing something like a 5 mill cut on steel but I suspect you will be playing pachinko in your shop if you push these really hard.I like that I can use these like a router for sign making pretty easily.
