Hi: I don't own a hitachi router, however most of the companies supplying router adapters make them to accept a Porter Cable guide bushing. PC guides fit into a 1 3/16th hole in the base plate or adapter. The guides are threaded and have a lock ring that fastens them in. If you buy a set of PC style guide bushings, buy the brass ones,
PC puts out a steel set but steel don't lock down well enough with hand tightening only. And should a brass guide come loose it won't damage your router bit.
Hope this helps.. Woodnut65
