What are collets?

There are four different sized collets available for the rotary tools – 1/8″, 3/32″, 1/16″ and 1/32″. A collet is a slim aluminum tube with small slits in the sides and an outer end, which is slightly larger than the shank that can be used with each collet. When the chuck cap is threaded onto the end of the tool, over the collet, the fingers of the collet (slots) close around the shank of the accessory and hold it into place.
