The white collar internet loves to blindly fetishize "quality" tools but professionals are always trying to strike a balance because every buck spent on overhead is a buck you're not getting paid and having breadth of tools is often more important than quantity since having the right tool matters a lot more than having a nice tool and if you don't buy nice tools you can afford to have the right tool more often. For secondary "luxury" tools that just make a job faster (like a ratcheting box wrench) many people buy the cheap stuff whereas tools you only use when you really need them (like flare nut wrenches) tend to be higher quality.
I still buy some Harbor Freight tools, especially if I only need it for a one-off job, but the higher-end tool names are often genuinely better, not just higher priced.
Whether a fancy ratchet is worth it depends a lot on how much you use your impact wrench. People tend to buy high end versions of the tools they use the most. There's plenty of professional roofers who have a $400 nail guns that weigh nothing and a couple clunky old HF framing guns on the truck. An electrician probably has a pawn shop or harbor freight hammer drill. The plumber probably has a nice hammer drill.
But if you're a young guy just getting started in a trade, and you can choose between a cheap socket set plus two dates with your girlfriend, or a premium socket set? 9/10 guys would choose the former.
It's usually either American, Taiwanese or Chinese, and a reputable shop like Angle Repair, for example, absolutely will not touch a Chinese torque wrench, and might only ever touch a Taiwanese torque wrench if it's a warrantied item on one of their supported brands, and probably only with some arm twisting on the part of the vendor they're doing warranty work for.
I don't know how much this is fetishizing versus simply having different priorities.
White collar tech people using tools are more likely to be doing so for hobby or recreation. They have spare money and their goal is a maximally enjoyable experience. With those priorities, it makes sense to buy better tools than you could justify economically.
That certainly wasn't my intention. My last roommate was an auto mechanic, then later a SnapOn dealer. He and the techs at the shops he serviced had massive rolling carts that cost $20k+ filled with another $30k in tools.
Certainly there were some cheaper tools in those carts, but as far as I could tell, they were mostly SnapOn or Mac.
There are some specialty tools that are sufficiently rare or expensive they'll get at trade-specific supply houses. Plumbers in particular can do the job either with a $5 saw and a bottle of glue or a $500 PEX expansion tool, depending on material.
The exception is something like high-end finish carpentry or furniture-making, which is high-precision, and does reward having professional tools and taking care of them. They have brands like Festool, which are available at specialty retailers.
I called my plumber late in the day and he stopped by on the way home from another gig. He didn’t have the tool on him, so instead he spent about 15 minutes forcing the handle of a socket wrench into the PEX so he could manually cram in a connector. It was remarkable, like watching someone tear a phone book in half. PEX is tough as hell.
If the sockets were this way, I would also expect that to be the same across the things like wrenches as well. The great thing about SnapOn is that truck. They will show up without the need for you to go somewhere. Their warranty wasn't any different than Craftsman's life time warranty, except you had to find a Sears.
Kind of beside the point, but you don't really even see pneumatics in construction much anymore. The _only_ pneumatic tool on my current project is my framing nailer. Every single other power tool is electric (mostly battery). Some companies are even making battery powered framing nailers now, and my corded worm drive saw finally broke after 15 years so I think I'll be upgrading to a battery powered saw in the near future. In a few years, I expect I'll be able to frame a house with entirely battery powered tools.
Shop equipment used to be done by trade show, not sure how it works these days.
Good stuff largely comes from wizard stores. They're mostly locally owned or small, regional chains with a few national chains most muggles haven't heard of. Electrical stuff comes from Needco, Rexel, and Graybar where I live. I bought some Klein screwdrivers at a Rexel, because Klein (and maybe Wera) are the last ones making decent screwdrivers generally and cabinet-tip screwdrivers specifically.
They were $9-$10 a piece instead of that much for a set, but they're made right, and they're readily available if you know where to look.
My handheld power tools mostly come from lumber yards or local hardware stores. And I happily pay more for Makita over DeWalt, Milwaukee, Rigid, etc from the box stores. Not looking to start a flame war over who makes better tools, but the Makita stuff is consistently excellent and priced fairly for the quality.
I've probably used a wider variety of routers than any other type of tool, and it's true that you get what you pay for, especially for plunge routers. The plunge action is just smoother and more precise as you go up in price. Bosch also makes a pretty good one, for what it's worth.
Though I build furniture, not houses, I end up shopping at a lot of the same places as carpenters. You consistently see Festool for handheld power tools (and I do own a Domino), Stabila for levels, Freud, Whiteside and/or Amanda for router bits, Freud or Forrest for saw blades, and Tajima for a wide variety of layout and hand tools. Tajima makes an outstanding chalk line and the nicest caulk gun I've ever laid my eyes on.
You might see Freud router bits at a box store, but never the selection that a wizard store stocks. You'll pay more, but the sales people know their stuff, and you can get it today, not tomorrow. That's worth a couple bucks if time is money. Incidentally, Freud also makes the Diablo saw blades that you find at box stores, and they're excellent value for the money.
Tools truly specific to furniture making are usually a specialist supplier. You can buy an approximation if a combination square or marking gauge at a box store, but it'll be less irritating to just take your money and light it on fire. Woodcraft and Rockler both have decent stuff if you're near a brick and mortar location. If you aren't, they sell online as does Highland Hardware, and a bunch of other vendors.
How do you know if you're in a wizard store or a muggle store? Wizard stores usually keep hours that reflect the fact that most of their customers are there during their workday, not on their time off. If a store closes by 5:30 and aren't open on the weekend, guaranteed they're a wizard store.
Mechanics (auto, airline) don't normally go to HD or Lowes - they buy from SnapOn, Cromwell, or Mac - all three send salespeople in large box trucks full of tools to work site. And all three offer credit and payment plans. And when tools break, those trucks come by with replacements.
