I have four Oneway Stronghold chucks. The latest one I bought used ,but in newly new condion. It was purchased new by a woodturning friend. My old keys have 11 cogs on the key and work well on all 4 chucks. The newest on has 12 cogs and doesn’t mesh well in any of the chucks including the one it came with. One rotation of the key and I have to to pull it out and reinsert it to rotate another rotation. The key was purchase with the chuck. Another one of my friends complained about the same thing. Does anyone have 12 tooth keys on their Oneway?
