Dremel 4000 vs 8220 Rotary Tool: Which One’s Best?
Both the Dremel 4000 and 8220 are perfect for engraving, sanding, and polishing. These two tools are very similar, with the primary difference being that one model is corded while the other uses battery power. Both use the same collet system for changing accessories like drill bits so you can interchange them between tools, and both have motors that output about the same power. In this article, we will look at all the differences to help you make an educated choice between the two.

Overview of the Dremel 4000
The Dremel 4000 is the corded version of the rotary tool kit capable of sanding, polishing, and cutting a wide range of surfaces, including glass and wood. It has variable control that you can adjust between 5000 and 35,000 revolutions per minute (RPM), and the speed control is separate from the on-off switch so you will not need to reset the speed each time you use it. A ventilation system helps keep the tool a little cooler, and the 360-degree grip is comfortable and easy to hold, even after long sessions. The high RPMs are possible thanks to the powerful 1.6-amp motor, and it is lightweight at 1.3 pounds. You can get to work at once with the four attachments and 34-piece accessories. It also comes with a 2-year warranty.
The primary downside to the 4000 model is that it gets a bit hot while you are using it, and sometimes it is better to stop and let it cool. It’s also not as portable, and the cord can throw off the balance of the tool, especially if you are at the edge of its range.
Overview of the Dremel 8220
The Dremel 8220 is the battery-powered version of the versatile tool. It uses a 12-volt battery to reach up to 30,000 RPMs. You can set the variable speed anywhere between 5000 and 30,000 RPMs, and the speed control is separate from the on-off switch so you can set it and forget it. It has a LED headlamp, so it’s easier to see the surface you are working on, and it also has a battery level indicator light to let you know when it needs a charge. It weighs 1.6 pounds, which his slightly more than the corded tool. The 360-grip is the same as is the two-year warranty. Purchase includes the battery and charger.
While the 8220 is much more portable than the 4000, you need to keep it fully charged or you will not get very much work done. Using this tool at higher RPM settings will cause the battery to lose its charge in just a few minutes.
The primary difference between the Dremel 4000 and 8220 is how they are powered. The 4000 uses a cord to deliver consistent power while the 8220 uses battery power to provide you with total portability. The 4000 can reach 3500 RPM and keep them there while the 8220 can only get to 30,000, and the RPMs will constantly fall as the battery dies with the 8220.
We give the performance award to the Dremel 4000 because it can reach a higher RPM and maintain it longer.
The price of these two units is almost the same. The difference in price between the two is less than $5.
Ease of Use
We award the ease of use award to the Dremel 8220. There is no fighting with the cord while working, and the LED headlight makes the surface easier to see.
What the Users Say
We’ve checked Amazon and any other online store we could find that sells these tools to see what other people are saying, and this is what we found out.
Both tools are extremely versatile, and it is not hard to think of 20 projects you can do with one at any given moment. Both are extremely capable, and the deciding factor comes down to how you intend to use it. If you are an artist or work in a shop that will use it every day, we recommend the Dremel 4000. The cord is a pain, but you will be sitting in the same place every day, so it’s not hard to work something out. The consistent power will be a huge advantage over the continuously diminishing power of the 8220.
If you intend to use it intermittently to touch up blemishes or other small jobs, we recommend the Dremel 8220. As long as you keep it charged, you can often use it to cut a bolt before you could plug the other model in, and the small job won’t suffer from RPM slowdown. You can use it under the car or in the tree stand without worrying about an extension cord.
