In this Instructible, I will tell you how to get the most out of your Dremel, from proper use of attachments, to safety and other various tricks I have picked up.
Step 1: Parts of Your Dremel + How to Attach and Detach Bits
By default, your Dremel will come fully assembled, minus a bit in the collet. However if you find yourself taking the parts off to clean them, you may want to know how to reassemble them. First screw on your rubber collar, this is shown in the first picture. Next insert the collet (Picture 2) and finally the cap (Picture 3). While this is still loose, insert your bit (Picture 4), hold down the shaft-stopping button and tighten the screw cap with the wrench.
Once the cap is fully tightened, you are ready to use your Dremel.
