The problem is that Snap-on doesn't do cordless. The unaware don't realize they're paying $350 for what, by all accounts, is really a $100 drill.
Even if a company doesn’t manufacture the components themselves, it’s possible in some cases to take off the shelf parts, and tweak those parts to improve performance where necessary, and there are also low volume industrial tool manufacturers who have to do this as part of their business model.
I have a Trumpf cordless sheet metal nibbler.
Trumpf is top of the line when it comes to sheet metal cutting tools, but unlike many power tool companies, Trumpf isn’t a motor manufacturer.
They purchase quality motors, mostly from quality German power tool manufacturers, like Fein, AEG, Metabo, Suhner, etc. and adapt those to their cutting heads.
For cordless motors they used to use AEG/Milwaukee “motors” or at least the motor housings, but when I disassembled one to clean some leaking grease, it was not a regular factory AEG/Milwaukee motor.
The motor had been modified with a giant heatsink on the end to draw heat from the brush area.
All the bearing used where European made, and where likely higher wuality than what is usually used in the AEG/Milwaukee tools normally.
Trumpf is very specific about the grease used in the gear housing, and lists about a half dozen specific types by manufacturer and number, and all these grease types seem to be somewhat specialized.
The spiral bevel gears were also highly polished, but I don’t know whether that was from use or factory spec.
Basically though, off the shelf components can be modified to increase performance by manufacturers, something that a company like Snap-On could do if they wanted to, but which major power tool manufacturers might not bother with because they aren’t making tools for industrial users, and it’s just easier to give a new tool to someone with an issue than to repair a broken tool or spend the extra to performance enhance all the tools.
Also, Industrial power tools usually have crappy warrantees, because if they didn’t, industrial companies might use them day in day out for assembly manufacturing 24/7 over multiple shifts, and then just kerp asking for new tools or repair service. Hilti for instance only comes with a 2 year warrantee, and construction crews usually can’t work 24/7 due to noise restrictions.
