Would that help? I live in the metric part of the world, and most of my tools are metric. I bought a set of ER11 metric collets from Aliexpress, but I’m using the standard nut supplied with the Nomad. Are nuts for metric and imperial collets different?
BTW, I noticed that the ER11 collets I bought do not support the bits on the rear end, like the collet shipped with the Nomad does. Should I look for better ones?
