Wasted $150 on fancy end mills I didn't even need
I bought a set of those coated carbide end mills for aluminum because the forum said they last longer. Turns out my old HSS bits cut just fine for what I do at my shop in Cleveland, and the carbide ones chipped on the first pass when I hit a clamp I forgot to move. Anyone else buy expensive tooling only to go back to the cheap stuff?

Those carbide bits are brittle by nature, so they punish you for one mistake while HSS just gives a little and keeps cutting.

punish you for one mistake" is a bit dramatic, I've snapped plenty of HSS bits just being careless.
