The wrench fits perfectly on my 1.5kW spindle, and I don't have to worry about my hand slipping with the comfortable grip.
I recently purchased a CNC machine and it was furnished with a set of wrenches for the ER20 spindle. I spotted the PwnCNC wrenches during a web search and ordered them. I am very happy with the replacements for fit and feel.
The 22 mm collet wrench that came with my Makita trim router is thin and uncomfortable to use, and I worried about high contact pressures damaging the wrench or collet nut. Standard combination wrenches are too long, requiring care to avoid overtightening the collet. So I set out to buy a 22 mm stubby combination wrench. Good luck finding one of those at a reasonable price! Then I found this PwnCNC collet wrench, and it was just what the doctor ordered. The head is 5 mm thick, vs 3 mm for the Makita wrench. The length is just right for a collet wrench. And with a comfortable molded-rubber handle, it's a pleasure to use.
