Maybe we are doing something wrong? Does anyone have any tips or tricks to making it easier?
Our set has a small flat on the top away from the cutting edge and we just use a set of channel locks or a wrench to break them loose. Very much important to wait for them to cool down before doing this as that makes it easier too and prevents burns from touching a hot cutter. We typically just grab the arbor in a vise and then break it loose so we can finish removal by hand.
