I'm not familiar with AliExpress but I agree with what ^^^^^^Ryan and Degen are saying. Carbide is the way to go in most cases.
Not sure what % cobalt is in AliExpress HSS stuff but if you could give us the size endmills you are currently using and toasting we can give you a good alternative in carbide which will save you money. In time spent alone your saving with carbide, never mind the frustration your dealing with what your destroying the cutters on.
Are you in Ontario by chance Paul?
