Just read this post and my recommendation would be either Öbergs or BACHO. Öberg as 1st chioice.
Mine are all BACHO or Öberg.

I don't doubt that if they're Chinese, they're crap. Although I've found a few good things from there, I generally expect low quality when considering a purchase.
With that out of the way, consider your use and care as well. You mention "gumming up", which may have more to do with the material you're filing, the match between file coarseness and material hardness, the cleanliness of your file, and perhaps speeds and pressure too. The latter seems to have more effect on premature dulling and chipping though.
Generally the harder the material, the finer the file. The softer the material, the coarser the file. Mix this up and you'll always be loading up your file with material.
Think of what kind of surface speed the file teeth are experiencing in use. You probably want to be in the HSS range or lower for whatever material you're working with.
Try slowing things down a lot, keeping your files cleaned and chalked, and you may find that you get more life out of a cheap set.
Sorry if any of this seems seems obvious to you, but I've watched even experienced machinists murder a file due to ignorance.

In all fairness Neo knows when some things crap.
Wont say how good I was but certainly currently in the top 50 filers worldwide and never read a book in my life or had tuition.
Cant say I never chalked a file, I tried it then no more.
Best advice is like most things 'get a feel for whats happening' Once learnt you will find any individual irregularities on each stroke, whether its cutting or not or more to the point whether its picked up and lodged debris in its teeth without looking. Soon as feel it picking up, change direction which should do any way, simple. Changing direction dislodges you just don't use a file in a forward stroke only such as a dovetail, no body told you.
Want to remove metal give it some no pussy footing around use a 3 square bastard 12", use the length of the file in one swoop diagonally at 50 to 80 rpm often changing directions barely moving feet. Some of us worked for a living anything less than around 30 full on 12" strokes a minute you were out the door, a files nothing comparatively to labour and overhead costs and usually the part making.
Mill scales the worst for knackering files up. Used to keep previous two of that type of file for similar situations.
Done some checking up seems all Bahco files are made in Portugal since 1992 owned by Snapon since 1999.
Do have a Bahco organiser for thread cutting inserts. For me to recommend I would have to personally see how they cut but are available every where cornering the market.

It was quite some time now, but I found them at a Sjörgens/Tools store at the time. Some of the items are not always on stock so these ones had to be ordered from central warehose somewhere.
The big ones in my collection are all 250mm/10" Bacho but the 100mm/4" ones are Sandvik & Öberg. The large ones work very well. Try to get a course variety (bastard) as that one will be good for initial work and then the standard medium or fine files will do the rest. The course one(s) may well be quite long for long effective strokes as well. I am on the lookout for a 12 to 14" medium-course.
Just checked the Tools product range and they also have Nicholson files which I also have quite good experience from. Would be interesting to know from others about the Nicholson range.
