Anyone have recommendations on a good thread file set (prefer US made)? was thinking it would be a good tool to ad to the collection and always look here for advise prior to making an investment. Thanks

I believe a lot of people have come to the conclusion that the thread restore set from Craftsman is about the best deal as it's not much more than the thread files cost by themselves.

The files by themselves can easily add up to more than the sale price of the set.
I've got several thread restoring files made by General, that I picked up for a buck a piece at the flea market, and an assortment of Snap On thread restoring dies, also of flea market origin. If I were in the market for new, I'd certainly consider this set.

The Craftsman set is made by Kastar/Lang, and the full set is online order only. They are the same OEM for the SnapOn and Matco sets. The warranty on the pieces varies with the branding FYI, so you'll want to pay close attention to that.

As for using them, I hardly ever do. I tend to reach for a small triangle file nine times out of ten.

You only need one: A 60 degree rat tail or saw sharpening file.

What I like about thread files over single files is you can keep a couple of rows of teeth in the good threads as a guide to keep you on coarse when reshaping the damaged threads. It helps when you are working on something in situ that, unlike bench top work, is difficult to reach or see.

For the life of me, I cannot understand the draw to a single edge 60 degree file.
A triangle file has THREE 60 degree edges. Yep, three for the price of not even one.

Though, now that I read the reviews in that Amazon like, I think I might understand.
One reviewer said that it is not actually a file, but instead forces damaged thread material back into place. So it's basically a 60 degree dull file. Interesting idea...
Like a sharpening steel for threads.

I like having thread files, thread restorers and taps and dies. Have never tried the 60 file but will certainly try one now. Its nice to have choices. Note, I buy most everything used so I can't comment on where to buy new.

Ive got a couple of the common 4-piece Nicholson sets that I bought on sale about ten years ago. They usually sell for ~$50 and cover the common standard and metric threads. On the rare occasion I need to fix an ultra-fine or other oddball thread I use a regular 60 degree file or one of my many dies. I dont waste time or room with thread chasers.

They can be very useful. If something is boogered up bad enough it won't do the trick. The thread chaser set I could see being useful, but I would rather use a tap and die. They all have a place and are good to have.

I tried one of those thread files^^^^^^and wasn't impressed. BUT, I only tried it one time so that is not a thumbs down by any means.
