Cordless or Corded Dremel: Which One to Choose?

The Dremel rotary tools can be very useful whether you are a hobbyist or professional. No matter what you need them for, it can be really confusing to choose between the cordless or corded dremel options.

There are a lot of models of Dremel rotary tools in both variations available. The corded ones operate on electricity, and the cordless ones get power from their batteries.

Both the corded and cordless Dremel tools have their perks and drawbacks. But at the end of the day, it comes down to what kind of work you do, how much, and of course, your convenience and personal preferences.

Below we are gonna compare both of them to help you make a pick among them.

Cordless vs. Corded Dremel

Cordless or Corded Dremel

Let’s compare both of them feature-by-feature.


Corded Dremel tools have much more power than cordless ones. The cordless ones are relatively weaker as they have to depend on a battery for power.

That said, some cordless models can be more powerful than older corded ones. Of course, it all depends and varies among the models.


Corded Dremel tools work better on some materials, such as steel and glass, than the cordless ones. But for some other materials like wood, the difference is not very noticeable.

Uninterrupted Work Time

The corded one won’t die out in the middle of the work, no matter how long you use it for. They are perfect for frequent use for unlimited periods of time.

On the same note, if you want to get a cordless Dremel, make sure you find out how long that specific model works on a single charge.

Project Type

The corded tool works best for small quick projects like craft or hobby type projects or minor weekend projects. They are also suitable for the occasional touch up around the house.

Although you do have to be in a hurry to finish your work with the cordless one. And if it does die in the middle of your work, wait until it is charged to get working again. The cord on the corded tool does limit how far you can go from the outlet.

It also somewhat restricts the way you can move the tool. Nonetheless, for heavy-duty projects, there are no questions about their suitability.

Wait Time

Corded one is always ready for use. There is no need to charge or recharge. You simply plug it into an outlet, and your tool is ready to go.

You have to charge the battery of the cordless one regularly, depending on how frequently you use it. Often times, you might find the battery to be low or dead, which means you have to wait for the thing to charge before you can start your work.

The battery of the corded Dremel is also known to drain after months of inactivity, so you would have to charge it anyway, even if you charged it previously before storing it.


Since the corded Dremel tools do not depend on a battery for their power, their durability is not restricted by the longevity of their batteries.

For the battery-operated ones, the battery will start to wear out eventually, as all batteries do. Even if you do not use the tool often, lithium-ion batteries deteriorate over time anyway.

Also, think about if the company stops restocking the battery for your model of Dremel. Then you would just be left with a paperweight after a few years.


Both cordless and corded Dremel tools are quite portable. But if you are going to be working in a place with no electricity supply, having the cordless option will come handy.

Ease of Use

Cordless ones are relatively heavier due to the batteries inside. This can make intricate works like engraving a bit hard and awkward. Your hand muscles can also get easily tired from holding it for too long. On the other hand, the corded Dremel tools are lighter and easier to work with.


There is only a small price difference between the two variations with similar specifications. But the corded one is relatively cheaper.


If the thing you are working on has no electricity outlet near it, your cordless rotary tool will come to the rescue.

Often times, you might find the cord getting in the way of your work, especially if you do detail work or crafting projects that involve a lot of elements. The flexibility of being able to move the tool any way you want without having to maneuver around the cord is what many people like.

For corded tools, the cord can come in the way of how you can or cannot grip the tool too. Sometimes it can even tug on the tool, making moving the Dremel tricky or difficult.

Dremel Cordless vs. Corded: Which One To Select?

All things considered, we think the corded Dremel wins over the cordless one. Unless you specifically need the ability to work without the cord, there is no need for you to go for the battery-powered one.

While we are at it, try to get one with variable speeds. It can make a significant improvement in your work, and give you a lot of flexibility.

We love having our eyes intact, and we assume you do too. Always remember to wear safety glasses while working with your Dremel. It’s a common thing to have bits and pieces of material flying towards the eyes, and safety glass can potentially save you from injuries.
