John,

Darren is correct, they are good. Especially if you are fitting an imperial cutter that won't automatically hold in the collet while trying to tighten up (usually a three handed job). You can screw them up enough by hand to hold the cutter, then bring the spanner in. Not normally possible with a standard nut, and worth every penny for that alone, the other things are bonuses.

Just two problems, you have to get them while available as he doesn't have them all the time, and they are also a bit tight initially getting the collets into the nose of the nut, but that soon disappears when you get the hang of it.

This is one for your size.

BTW, I use that seller for a few bits of my tooling, always good quality and reasonable in price.
