I was needing two 32mm open end wrenches to work with my wood lathe, found some single wrenches but at quite a bit of money, especially since I wanted 2 wrenches. These were close but a little too small but with a little filing to enlarge the opening they were soon to the right size.Very sturdy and well made. I like the rubber grip, much more comfortable to use, especially in a cold unheated shop. They also are thin (but not so thin such that would make them weak, these are NOT weak) so that they can fit easily on the headstock spindle and faceplates, etc., just the right thickness since some wrenches are TOO thick, for example adjustable wrenches are too thick to work in a narrow space.I'm very satisfied with these even though I did have to spend a little time getting them to the right size. With that in mind, they were a perfect pair for an excellent price.

Nice comfortable wrench for ER20 collet nut.It's the correct size. Good fit and thick enough that it grips the nut well

For you hand loaders out there that use RCBS Dies. This fits Perfectly. I looked a long time for a reasonably priced wrench. This fits the billet. We all know how much the RCBS factory wrench sucks. To be CLEAR i can NOT speak for other Die Manufactures. This does work on all my RCBS locking rings. It is pretty rugged.

not a big deal, it's a tool -- but for the price & being brand new -- the black coating was very noticeably scratched on the face of the wrench in multiple places

This wrench was fine, but I wanted more leverage on my CNC spindle for easy bit changes...

Good fit and finish with a comfortable grip. Avoids the need to use a full size 30mm wrench to tighten an ER20 collet holder. I would definitely purchase again.

Fits the hand nicely and allows for easy cinching, and loosening.

I was using my 2 adjustable wrenches for making bit changes which worked but was inconvenient when I needed those wrenches for another task. This along with a 21mm wrench have freed my adjustable wrenches for higher purposes. If you have a CNC with an er20 collet this will serve. Nothing earth shattering about it, but you can change bits with it.
