Dremel is the standard in the rotary tool market for a reason. It sets itself apart by providing best-in-class tools that can be used for several purposes.

For example, your Dremel is useful for a wide variety of hobbies or crafts. The company has been in the rotary tool market for a long time, and those that use their tools often stick with the Dremel brand.

The Dremel 4000, like nearly all of its rotary tools, includes several different attachments which will make things much easier as you go along. This easy to use device doesn’t require much knowledge or training beforehand. Open up your manual, follow the instructions, and have at it!


You’ll discover plenty you like about the Dremel 4000 as you use the device for various projects around your home. But what features does it have to offer? Let’s take a look at some of the benefits of owning a Dremel 4000.

It’s Electric

You won’t need batteries to get your Dremel 4000 up to and running. It works using electric power, which is much more convenient than needing to change the batteries every few weeks. It only requires 120 volts, so you’re not going to need a ton of power when you’re using your tool.

Included with the Dremel 4000 is your power cord, so you can plug it in anywhere you have access to an outlet.

Adjustable Speeds

The Dremel 4000 has a variable speed option that opens up at 5,000 RPM. If you like to live on the edge, you can push the tools all the way up to 35,000 RPM. It’s this type of adjustable speed that makes the Dremel 4000 a very popular tool among those who require this type of device.

Having the ability to change speeds with a rotary tool is critical, especially if you work on hard surfaces that require the consistency associated with Dremel tools. High speeds help to enhance the performance of the tools itself.

Additionally, variable speed control gives you the control you need to adjust based on what type of project you’re working on. Even though you can crank the tool up to 35,000 RPM, you don’t have to worry about burning the motor up, which is something other rotary tools can’t claim.

Power Switches

The on/off switch on the Dremel 4000 gives you the granular control you need when you’re working on an important project. You’ll also find a switch which controls the speed, so you can find the perfect setting for the type of work you’re doing.

Lightweight and Compact

Of course, when you’re working on things around the house or making the perfect gift, you want a tool that doesn’t weigh a lot or take up a lot of room. The Dremel 4000 meets both those requirements, checking in at a little over four pounds and measuring roughly nine inches in length.

With a lighter tool, you can spend more time focusing on the project at hand without getting tired. Plus, you can easily carry your Dremel 4000 from one place to another. Just pack it in its carry case and take it wherever you need it.

360-Degree Grip Zone

Arguably one of the best features available with the Dremel 4000 is its 360-degree grip zone. With this feature, you have the comfort you need when using your rotary tool. It allows you to grab your device and turn it any way you need it for hours on end.

With its 360-degree grip zone, you’ll have the control you need to turn the Dremel 4000 in various directions and positions. Plus, having a strong and 360-degree grip will help reduce the chance of injuring yourself as you use your Dremel 4000.

EZ Twist Accessories

It can become frustrating if you need to switch out your accessory, but it takes five minutes just to remove one and connect the other. With the Dremel 4000’s EZ Twist feature, you use the included nose cap wrench to quickly and easily change out your accessories.

Answer: You can use the Dremel 4000 for a wide variety of projects and purposes. It will work for polishing, drilling, brushing, sanding, grinding, and many, many other uses.

Question: How many accessories come with the Dremel 4000?

Answer: The rotary tool comes with two attachments and around 30 different accessories. With that many accessories, you can be sure you won’t have any problems getting the job done.

Question: Do Dremel accessories work with all Dremel rotary tools?

Answer: While some Dremel accessories are interchangeable with other Dremel devices, the company has developed a universal adapter that allows it to work with a wide variety of tools. However, keep in mind that there are some Dremel accessories that have speed limits.

As a result, you can use your Dremel accessories with other rotary tools, including those available through Bosch, Fein, Ridgid, Rockwell, Craftsman, and Masterforce.

Question: Can you use Dremel bits in a regular drill?

Answer: Unfortunately, you cannot use your Dremel accessories in a cordless drill. Additionally, you cannot use your drill bits with your Dremel 4000, as the bits are too wide to fit into the device. 

Question: What are motor brushes and what do I need to do with them?

Answer: The motor brushes for your Dremel 4000 behave in much the same way the oil in your car does. You’ll find them in the brush holder, which is under the brush doors on both sides of your Dremel 4000. If you’re having trouble finding them, just pull out your manual for more information.

You’ll want to check your brushes every 50-100 hours. If they measure less than 3mm, you’ll need to change them out. If you do wind up changing out the brushes, be sure to let the new ones get seated properly by letting the Dremel run for 5 minutes with no load.

Question: Why does my Dremel 4000 get hot when I use it?

Answer: There are several reasons why your Dremel 4000 could get home when you use it. There are also a few things you can do to help prevent it from happening. The first thing you want to do is to be sure that the vents are open and unblocked.

Air running through the Dremel 4000 as you use it needs a place to escape, which it does through the vents. Be sure your hands aren’t blocking the vents as you use it. Doing so would cause the device to quickly overheat.

Most people hold their Dremel like a pencil. If you do, use the Detailer’s Grip so you have more control. It also keeps you from covering the vents.

Additionally, if the task your performing is labor-intensive or requires you to run the Dremel at 35,000 RPM, you could be causing the motors to heat up. Plus, using materials like metal that easily get hot can also result in a lot of heat.

Question: Is there a way to make my accessories last longer?

Answer: While some accessories for your Dremel 4000 are going to last longer than others, the thing to remember is that they all work on speed. Neither torque nor force comes into play when it comes to accessory longevity.

If you discover that you have to push an accessory as opposed to guiding it, then you might not be using the accessory meant for that material or use. The Dremel 4000 has plenty of accessories that are capable of a wide variety of uses.

As a last resort, you may want to check out the Dremel FAQ section on the company website. It will offer tips and tricks on how to get the most out of your accessories.

Final Thoughts on the Dremel 4000
