How to Change a Dremel Collet
One of the beauties of the Dremel rotary tool is the large number of accessories it can use. Some accessories, however, may have a different size shaft that others. This means you may have to change the collet at the top of the tool to best fit your chosen accessory. Changing the collet is easy to do and ensures the accessories fit properly for your safety. Does this Spark an idea?

Disconnect the power source. Unplug your Dremel, if it is electric. Remove the battery, if it is battery operated. Press the buttons on either side of the battery and pull out the battery while the buttons are depressed.

Pick the collet you want to use. Choose from one of four collet sizes that fit standard Dremel rotary tools. Make sure it is the size collet that fits the size of the attachment you wish to use.

Take off the collet nut. Press the shaft lock button, located right below the neck of the Dremel tool. Unscrew the collet nut, which is the large nut around the collet. Loosen it by turning it in a counterclockwise direction while the shaft lock button is pressed. Use the collet wrench that comes with many Dremel or another small wrench to loosen the collet nut if it is tough to budge. Remove the collet nut altogether so the existing collet is fully exposed.
