The shift to only using carbide inserts for everything seems wrong to me
Most guys in my area swear by carbide for every job, but I still keep HSS tools around for certain materials. We tried running aluminum with only carbide and it just didn't work as well as the old high-speed steel. There's a place for both in a good shop.

Agree completely, aluminum just melts away better with HSS in my experience. Some jobs honestly call for the older tools. A good machinist knows to use what works best for the material.

Carbide beats HSS for aluminum every time.
