For 18 tpi (= 19 ppi) you can certainly use a 4 dbl x-slim, but I wouldn't use an x-slim 4" file.
You can get a 4" dbl x-slim Grobet from Pete Taran at vintagesaws.com, a 2" needle file from The Best Things, or a 4" needle from Joel at Tools for Working Wood.
3 squares are getting less useful even in the smaller sizes. The edges are flats and even the smaller sizes they have gotten as wide as the Grobet 4" dbl x-slim so there is actually a cost savings just getting the taper saw file.
The edges on the needle files above are nice and crisp. Either will serve you well.
Take care, Mike
