That's called a crimping tool. They grow on trees. They're designed to achieve the correct amount of force to make a gas tight, permanent connection without destroying the contacts. All you need to do is select the correct connectors for the wire size you're dealing with and squeeze it.
Good luck with that. There are all kinds of crimping tools.
I watched a professional cable installer once crimp the coax F connectors on. I got the manufacturer and model number of it. It's from an outfit that only sold to professionals, and cost about $200. Since I was going to pull all the coax myself in my house, it was worth the money and I haven't had trouble with the results. The consumer grade crimping tools from the hardware store are terrible.
