How are you supposed to know what crimp tool to use for a given connector?

There is a dizzying array of crimping tools available on digi-key, mouser, and other distributors. But they nearly always just say they're for specific wire gauges, without reference to what type of connector they're meant for--and just today I came up against a problem where a crimping die I'd paid $50 for turned out to not work at all for the terminal I was trying to crimp onto the wire; even using the 6 AWG hole didn't fit (it's 8 AWG wire with an ordinary uninsulated brazed-seam lug). How are you supposed to know which tool to use for which type of crimp? I'm aware that manufacturers usually list a specific tool to use, but I can't afford to pay$3000 and wait out a ten-week lead time just to get a few terminals crimped onto some wire.

It'd be greatly appreciated--and hopefully of use to others as well--if someone could give a run-down of different types of common crimp connectors and what sort of tool they're intended to be used with.

• @DKNguyen I'd prefer to not spend \$50 on a crimp die just to find out it doesn't work, though! Dec 5 '20 at 1:40
• And every crimp tool I see does say what type it is meant for. I compare the shape against the official crimper. Dec 5 '20 at 1:40
