Review on 🔧 Milton S-445 Multi-Purpose Valve Tool by Nathan Kumar

The valve tool is smaller than I expected, only 1¼" tall and 1¾" wide. It consists of 4 tools: 1) a valve removal and installation tool, 2) a male thread repair bit, and 3) a tapered tap and 4) a non-tapered tap for cleaning or cutting female threads. Fairly good quality dies and taps, probably not suitable for cutting new threads in hardened steel, but suitable for repairing threads in a brass valve. Punch or tap, which is difficult because the tool is so small. I suggest using an adjustable vise to hold the tool while threading - the length of the handle makes it easy to ensure the tool is perfectly aligned (and stays aligned) as you cut. It can be difficult to find a vise that is the right size, but they are available. I made my own pin vise using an adjustable Dremel chuck and a hex extension I accidentally had laying around. Be careful when re-cutting, don't cut more than 1/2 turn at a time, then back 1 turn, repeat, repeat, repeat as needed. Lubricate the tool and valve before cutting (ideally use a 3-in-1 oil). After a few full turns it is recommended to completely remove the tool and remove the metal shavings, add more oil and repeat if necessary. If you're cutting internal threads, you can wipe the inside with an oil-soaked cotton swab - you don't want metal shavings clogging your new valve. When tapping internal threads, don't overdo it. - Cut the threads with a non-tapered tap - you want a tight fit and you don't want the valve to be under seated when reinstalling. I recommend NOT using a taper tap unless you are sure of when and how you use it - it's too steep and probably very difficult not to accidentally cross threads. . Luckily, it's easy to take apart with a hammer. Soak in penetrating oil (or WD-40) for a few hours beforehand. Insert a cone tap into a hole (ideally hardwood or plastic) that is at least 1½ inches deep. Then tap the other end with a hammer and protect the non-tapered tang, maybe with a coin. > Click 'stone' just below the product name to see my other reviews or leave a comment to ask a question.
