Generally, "laminate trim bit" and "flush trim bits" are considered to be the same thing. The only thing I'd watch out for is the shank diameter. Some bits sold as laminate trim bits may be designed for use in small laminate trim routers. And some of those may have funky shank sizes, special shafts, etc. If you buy something with a 1/4" or 1/2" shank, they're generally all the same.
