(More customer reviews)I purchased a different brand, but it appears to be identical.
The valve tool is smaller than I expected, only 1¼" tall, by 1¾" wide. It consists of 4 tools 1) valve removal/installation tool, 2) a die for repairing the outside threads, and 3) a tapering tap and a 4) non-tapering tap for cleaning or cutting the inside threads.
The die and taps are of fairly good quality, probably not suitable for cutting new threads in hardened steel, but adequate for repairing threads in a brass valve.
Because the thread pitch (18/inch) is rather fine, great care should be taken not to cross-thread the die or taps, which is difficult because the tool is so small. I suggest using an adjustable pin-vise to hold the tool when cutting threads--the length of the handle makes it easier to be sure that the tool is perfectly aligned (and remains aligned) as you cut. It may be hard to find a pin-vise large enough, but they do exist. I made up my own pin-vise with a Dremel adjustable chuck and a hex extention which I just happened to have lying around.
If the threads are badly damaged (or in my case, never properly cut in the first place), you should be cautious in recutting them, cut at most a half-turn at a time, then back off 1 turn, repeat, repeat, repeat as necessary. Oil the tool and the valve before cutting (ideally using 3-in-1 oil). After cutting several full turns, it is a good idea to remove the tool completely and clean off any metal shavings, add more oil, repeat as necessary. If cutting the inside threads, you may wish to swab out the interior with an oil-soaked Q-tip--you don't want metal shavings to jam up your new valve.
If you are cutting the inside threads, don't over-cut the threads it with the untapered tap--you need a tight fit, and you don't want the valve to be too deep when you reinstall it. I suggest NOT using the tapered tap unless you are certain when and how to use it--it is too steep and probably very difficult not to accidentally cross thread.
Even though the tool is small, it can get in its own way in tight spaces. Fortunately it is easy to disassemble it with a hammer. Soak it in penetrating oil (or WD-40) for several hours in advance. Place the tapered tap in a hole (ideally in hard wood or plastic) at least 1½" deep. Then tap on the other end, with a hammer, protecting the untapered tap with perhaps a penny.
