Why don you include the collet nut and collet with the Flex-Shaft?
We include the driver cap. Remember, the driver cap is the nut with the square hole. You can see the square hole when you hold the nut up to the light and look through the opening. You need the driver cap to “drive” the cable of the Flex-Shaft. If you have a rotary tool, you already have a collet nut and collet. It comes on the end of the rotary tool. To make the Flex-Shaft work, you need to remove the housing cap (the threaded part of the nylon housing), the collet nut and then the collet from the rotating end of the rotary tool. The chuck cap and collet will be put to use on the end of the handpiece. The driver cap (nut with a square hole) goes on the end of the rotary tool where you removed the collet nut, collet and housing cap.
