These bits have held up well enough so far. I've only used them with aluminum, and manual machining. They cut well, seem to hold their edge fairly well, the make nice small chips, so no big strings of aluminum to get caught on anything. I've been happy enough with them, haven't broken one yet.

At a price of just less than $10 each for a carbide end mill, it seemed worth the risk to give these a try.I'm manual machining, not CNC but do work on some odd parts with harder steels.These actually seem to be doing fine - the cut is quite good and they had no problem making typical depth cuts.The marketing is a little confusing - end mill - spiral router bit - I'de say these are typical of a four flute, center cutting end mill but I know they can cross over depending on your situation.These do have a chamfer on the corner - which is fine for what I have used them for.Overall, seem like decent end mills - I have't pushed one to see just how much abuse they can take but they are cutting well and leaving a nice finish -
