So I must have sprained my sore wrist again taking these bits out of their holders. They are literally glued there by the reaction of a rubber retaining ring and a metal shaft. Wow it took me 20 minutes to really tighten, twist etc etc etc Finally I cut out the little tabs at the bottom that hold the bits in each rubber septum ring. Then the last 3 came out easier because I had to remove the rubber ring, pull, twist, etc. Don't forget to wear rubber gloves so you don't cut yourself. I'm hoping to actually use them with my new CNC router after I've healed my new sore wrist injury. After loosening the rubber rings, push them out and continue without pushing the shaft in too far. Documentation for each bit is also pretty sparse. FREUD, what have they done to you. 😒🤔😜
