As noted, both of the answers about the crimp tool are incorrect. A tool with a hex die size 0.36" is needed. This tool works well:-

Use a standard two blade coax cable stripping tool, push the cable into the plug so the inner core protrudes from the end, then crimp the ribbed section of the plug. The result is a neat hex ended plug.
