I love my tap and die set, super useful and paid for itself multiple times over, but the design of the adjustable tap wrench has always confounded me. It’s just strange. I understand the need for wider and dual handles for leverage and balance, but why do both sides need to be threaded? And why is the part you apply force to when tapping also the same part that loosens jaws? Couldn’t you just have stationary handles, and then a separate thumbscrew 90 degrees to the handles to lock the bit in place? One side always comes loose while turning it, the tap slips out, falls on the floor, or the jaws loosen and the wrench slips around the square tap, rounding it over. Or why not just mill the tap top a standard 1/4″ hex and call it a day? Why couldn’t they thread it just a little finer so it stays tightened during use, or put a lock washer in there? All it’s doing is compressing the jaws.
Even super expensive ones have the same exact design.
