Here we have discussed 5 easy steps to change the Dremel bits.

  • Step 1: Turn Off and Disconnect the Dremel Tool
  • Step 2: Press Down Shaft Lock Button
  • Step 3: Unscrew The Metal Collet
  • Step 4: Removing The Plastic Housing
  • Step 5: Remove The Metal Collet

Let’s discuss each step in detail.

Step 1: Turn Off and Disconnect the Dremel Tool

Obviously, you know that, but again, you MUST make sure to disconnect the Dremel tool from any power source before removing it a bit. If your Dremel rotary tool is a corded one, make sure that you have unplugged it. If you are using a cordless one, make sure to remove any batteries before you start to fiddle around with it.

Like we said, if you are an experienced power tool user, then this is all going to be reasonably common-sense stuff. Still, it’s always better to remember the safety precautions, especially when you are working with power tools, as they can hurt severely. 

Step 2:Press Down Shaft Lock Button

The foremost thing that you need to do is identify the shaft lock button. You can find it near the front part of the tool.

It can be different in color from tool to tool. In some models it is blue, on some it is silver. But it is easy to locate as it is the large button right near the front end. Please press the button down and hold it, and that will loosen the bit.

Step 3: Unscrew The Metal Collet

You will find at the front of the tool the metal collet, which keeps the bit in place. Use your free hand to start slowly unscrewing the collet at the end while holding the shaft lock button pressed firmly. 

It should come off without much of a hassle.  But depending on which state your tool is in, you may need to put in a bit of elbow grease. Even if it seems funny at first, keep going at it, and eventually, it will come loose.

Step 4: Removing The Plastic Housing

You will find the housing cap at the front of your Dremel tool. This provides an area to grip the tool and provides some protection for the internal parts of the tool. Nevertheless, when you need to change the tool’s bit, you have to remove it. Thankfully, the task is a straightforward one. Much like with the metal collet, you just have to unscrew it with your hands.

Step 5: Remove The Metal Collet

After the plastic housing is gone, you can entirely slip the metal collet off of the tool. Once the metal collet is away from the tool, ensure to put it into the metal collet nut. This is very vital.

Attaching A Dremel Bit

When attaching your new Dremel bit, you kind of have to work backward. But there are some modifications, and we will highlight those factors. 

Step 1: Putting The Bit On

In the last section, we talked about putting the metal collet into the metal collet nut. And, the next step is to attach the bit that you want to insert into your Dremel tool onto the end of the collet. DO NOT FORGET to make sure that it is securely attached.

Step 2: Reattach the Plastic Housing

There were some variations when you attach Dremel bits. The most important one is that you do the plastic housing first. Reattach the plastic housing that you unscrewed in the earlier steps. In addition, you have to resist your base instinct to tighten it. You will reattach the housing and don’t tighten it just yet; you will do it later.

Step 3: Inserting The Collet Nut

Insert the metal collet nut into the shaft of your Dremel rotary tool. You can begin to tighten it by hand. When you feel that the bit is placed securely, press the shaft lock button we mentioned at the beginning of the article. Remember what we said; you have to push, not hold. 

Step 4: Tighten The Housing

Alright, your bit is back into place, and now you can tighten the plastic housing. Ensure that it is very tight and very secure. Congratulations, you have successfully changed your Dremel bit.
