Save barn tap and die sets.

can't actually see the bows, they are often the weak tool in sets of taps, but they give the impression they have sliding blocks in them - which is good, some of the cheap ones use the end of the threaded rod to hold the taps, and they don't hold the taps well at all = broken taps especially in the smaller ranges

the dies are split dies so are of a better quality than a lot of the sets you find

overall I'd snap then up at that price ( cos I have a couple of bows here that will do if their ones are of a lessor quality

Couldn't comment on the quality but those combined SAE and metric sets are going to be a bit of a compromise, they simply omit too many thread pitches. I was looking for one last year and was tempted by a few but ended up spending $300 on a very comprehensive metric only set which did all the more unusual pitches all the way up to M18 and another 100 on a fairly complete SAE job that was going to cover all I would ever do with it. I also use a small Ampro set at home which goes to M12 which is pretty good quality for the price, which again was about $100.

Have a serious think as to whether you will need the SAE parts of the set.
If not, look for an all metric one.

I just buy a smaller selection of quality taps and dies. i have 3/16 and 1/4 bsw. then 3,4,5,6,10mm. and 1/8,1/4,3,8 bspt taps then 6,10mm dies. seems to work so far. nothing worse than having a poorly tapped hole strip out.
