It all comes down to the basic hardware status, and you will need to service it on a weekly basis. 

After a few years of usage, they go bad, and the collet ends up getting deformed, but there are some ways for you to tighten them up.

So, with the section below, we are sharing how you can tighten up the Dremel collet.


  1. First of all, if you are using the electrical Dremel, you need to disconnect it from the power connection by taking out the power cord. On the other hand, if you are using the cordless model of Dremel, you only need to hold the battery release tabs on the Dremel’s back and take out the battery from the unit
  2. When the battery is out, you have to press the shaft lock button and hold it for a longer time (it is usually available on the top of the Dremel). Also, this lock button is an on/off switch available in the form of a small button
  3. Now, you have to place the collect wrench around the Dremel’s collet nut. Also, the collet nut is defined as the knurled sleeve that surrounds your rotary tool’s collet
  4. Lastly, you need to turn the collet nut in a clockwise direction with the help of a wrench. Once the nut is tightened up, you can use it as you like. However, you need to be careful about the tuning of the nut because counterclockwise turning will result in a loosened collect, and you don’t want that. So, turn it in the clockwise direction

In addition, the collet wrench should be put around the collet nut to ensure you have a better grip on it.

In the majority of cases, the collet wrenches are provided with the Dremel tool, but if you don’t have it, you can also purchase your own wrench from the hardware store.

It all comes down to the availability of tools, and tightening up the Collet can be hard because of the collected gunk and debris when you ignore the maintenance.

For this reason, all owners are pointed towards keeping the unit fully maintained over the years. 

It will take a bit of time to get used to the maintenance cycle. However, you will need to put in this time and keep track of the system’s hardware to get an optimal response.
