I had to take them out of the box. Hand extraction can be dangerous for your hands as most attachments are quite sharp. The clear plastic inserts were too tight, so I greased them with vegetable oil to make the bits slide out easier. The box is quite stable and well made. I will attach a picture of a tailor with an attached insert. Now I need to design a router table on my Dremel workstation so the router will cut the tree from above. We also hope this will prevent dust and chips from getting on the rotating tool so it will last longer.
