Used to swear by HSS end mills, switched to carbide and now I get it

Honestly, I ran HSS for years because I thought carbide was too expensive and brittle for my little Haas mill. Then I had a job in stainless steel, 30 parts, and I was swapping tools every 3 pieces. Buddy loaned me a single carbide end mill and I ran all 30 without a change. The cycle time drop and surface finish sold me right there. Anyone else have a tool material conversion like that?

Damn, that stainless job was the exact same thing that converted me.

Got a nice set of Wusthof knives a few years back after using cheap ones forever and it's night and day, even just chopping onions feels different. That moment when you realize the tool was holding you back the whole time really sticks with you.

Tbh it's actually wild how that pattern plays out everywhere, not just in machining. I noticed it with my kitchen knives too. Used cheap stamped steel for years, thought "good enough" until I got a single decent carbon steel chef's knife. Suddenly everything sliced cleaner, held an edge way longer, and I wasn't sharpening every week. Same thing with my drill bits at home. Once you feel that difference in hard use, you can't unsee it. It's like our brains are wired to accept the default until something forces us to try better.
