Dremel is a rotary tool with various attachments and bits to allow you to do everything from sanding to drilling. The bit is the part of the Dremel that does the cutting. It needs to be changed regularly depending on the task at hand. Here we will show you how to change the bit on your Dremel.
How do I change the bit on my Dremel?
- Turn off and disconnect your Dremel from the power source. Unplug your Dremel tool if you have a model with a cord, but if you have a cordless model, take out the battery. That is done to ensure that you do not accidentally turn it on, thereby preventing accidental injuries or damaging the tool.
- Press down and hold the button on the side of the Dremel near the chuck nut, which is the outer metal part at the tip of the Dremel, holding the bit. There is a small button on the side of the Dremel near the chuck nut. Hold it down. The button is a security lock that loosens the chuck nut so you can replace the bit.
- Use a wrench to turn the chuck nut counterclockwise to loosen it. Dremel tools come with a small wrench that fits the chuck. You can use any other wrench that fits if you have lost the wrench that came with your Dremel. Loosen the chuck nut with the Dremel wrench and use your fingers to unscrew it. Pull the bit out.
- Remove the bit from the collet. The collet is the small metal part inside the chuck nut that holds the bit. Set it aside in a secure place.
- Put the new bit you want to use in the collet. Loosen or tighten the chuck nut with your fingers to adjust the collet to the size of the new bit. If the bit you want to use is too big or small for the collet in your Dremel tool, replace the collet.
- Tighten the chuck nut with a wrench to secure the new bit in place using a Dremel tool. Your Dremel tool is ready to use with the new bit. Changing a Dremel bit is similar to changing any drill bit. The way you release the chuck nut and loosen the collet differs from tool to tool, but the concept is the same.
How do I attach a Dremel attachment?
- Turn off the Dremel and unplug the power cord from the wall outlet to avoid injuries. Locate and hold the collet lock button with your thumb.

- Insert the shaft into the center of the collet until it seats into the Dremel. Twist the collet nut clockwise until it is hand-tight. Turn the nut another 1/4-turn with the wrench.
- Remove the nose cap on the front of the Dremel if your accessory requires attachments such as grout removal, chainsaw sharpening, and a multi-purpose cutting guide.
