I think you can find even cheaper ones on Amazon, the hook style ones are around $8US, and the same style you linked to can be had for as little as $11US. All with free shipping with Prime.
We normally use a hook style end on a torque wrench for tightening (to 90ft-lbs on ER40 collet nuts and 80ft-lbs on ER32), but use the style linked to below (with a cheater pipe for the ER40s) for removal. We have managed to rip the teeth off of a couple of them over the years. We also have a number of SYOZ-25 tool holders, they can only use the hook style wrench and can't take as much torque as the ER, but don't need it either with their steeper tapers. Todd Zuercher P.

Today the ER-32 collet set arrived. I no longer have an excuse for not completing my 4th axis driven by a real harmonic drive. (Well it is raining and can't cast). So I have drawn up the face plate adaptor and that looks to be a pretty easy LCNC project for the mill plus a bit of lathe work. However, I foolishly did not order a collet wrench. This seems to overall be a pretty easy CNC project with the exception of the 'teeth' that engage the collet. I suppose I could mill out the profiles in some oil hardening steel, then file the teeth to have straight edges. Finally harden it. Alternatively make it out of 1/4" or so steel plate (or even aluminium) and drill and tap holes for screws to protrude out where the teeth are. Turn down the screw ends to be smooth or even square and lock the screws in place. Looking for suggestions here. Don't really want to wait 2 months for one wrench with either low price and horrendous shipping or high price and low shipping. Cost ends up being the same at about $28.
