dremel 8000 vs 4000

Differences Between Dremel 4000 and 8000 

From the get-go, the major specification differences are given below.

  • Variety

To start with, let’s consider the difference in variety. The Dremel 4000 comes in 3 size varieties, while the Dremel 8000 comes in the more famous 2 forms (from a total of 4 forms). 

Different sizes come for different purposes depending on the handyness, portability, and compatibility. To manage a small and precise art of work, you would need a small-sized rotary machine and for heavy-duty work, you might need a larger size.

The size variations of Dremel 4000 are – 6/50, 2/30, and 4/34. In 8000, they are a 03 and a 05. You can choose whatever size fits you the most, and apparently, the size of the rotary machine depends upon the projects that you deal with on a regular basis.

  • Cost

Since there are three size variations in Dremel 4000, the costing varies too. The 6/50 is costlier than 2/30 and 4/34. These three, when compared to Dremel 8000 – 03 and 05 versions, are affordable. Not too high or too low on the money bar.

Check out your budget and look if you can afford the one you need. Financial ability plays a vital role not just to buy stuff, but also to maintain that. You might need extra money to buy additional accessories if you need one.

  • Accessories

6 attachments and 50 accessories of the Dremel 4000-6/50 is a ‘power-packed kit. Next, the 2/30, just as the shorthand signifies, has 2 attachments and 30 accessories. And, lastly, with 4 attachments and 34 accessories comes the 4/34 type. 

Well, you can see how versatile it could be to work with these machines and their huge number of accessories. 

The two sub-versions of Dremel 8000 are at opposite ends of the spectrum. The 03 has 40 accessories, while the 05 has 0 accessories; they are sold separately. 

The function of the 8000 seems much different than the Dremel 4000 as you can see that no accessories mean that you have to buy all the accessories separately.

  • Proportions

For Dremel 4000 sub-types, there is not much dimensional difference, with only an inch or two. Whereas with Dremel 8000, there are no inch differences at all; both are exactly the same size. 

The dimensional difference can only affect the handiness and portability, which in these cases do not get affected much. So, the proportion is not much of a problem here. You can choose whichever you would feel like buying.

  • Voltage Consumption

There is a massive difference between Dremel 4000 and Dremel 8000 in this aspect. Although the subtypes have the same voltage use. Here, the difference is huge because of the corded and cordless features. 

Since the latter is cordless and battery-powered, it has to be operated on a low voltage depending on the ability of the battery that it has been equipped with.

For the former, the voltage used is as high as 120 V, and for the latter, it gets as low as 10.8V. If you have a voltage problem at your household or at your workplace and if you think that you might struggle with the voltage then go ahead and choose Dremel 8000 because of its battery dependency on low voltage. 

If you do not have something to worry about like the voltage or electricity and you are fine with a corded rotary machine then choose the one and only Dremel 4000.

  • Mechanism of Working

Dremel 4000 and its further classified types are all based on motor-based working. They all involve ball-bearing action, motor brushes, and other such parts that usually work in a motor mechanism. 

The work of a rotary machine is that it has to work fine, precise, and be fully functioning, be it the smallest and minutest of work or for heavy-duty things. Au contraire, the Dremel 8000, works on a non-removable, rechargeable lithium-ion battery. 

No motor workings involved. So, the effectiveness of work on your project would definitely change when you will use a non-motor device. It might not be as strong as the 4000 and could not be useful in every scenario.  

Similarities Between Dremel 4000 and 8000

  • Pace

The operating speed or tempo is the same in all 5 versions, including the 3 sub-types of Dremel 4000 and 2 sub-types of Dremel 8000. Hence, momentum-wise, they are incomparable because of their similarity. Here, we have the first similarity and it is one of the major factors which is the pace that a rotary machine would work. 

The pace is what keeps up with precision; if the machine has a good speed, it would work faster and also can work more accurately providing you a fine and stylish project work.

The minimum and maximum ranges for both types are 5000-35000 RPM. There is no difference in speed settings, even though there is a noticeable difference in voltage consumption. 

It is not so believable that their speed is the same regardless of the voltage consumption, but you might see a difference in the power when you would deal with heavy-duty project work. 

  • Production Brand Name

Some of the rotary tools of Dremel have been copied or, instead, have been inspirational pieces for other companies. So, other competitive brand names indeed have manufactured similar-looking tools, with very close to original specifications, but of course, do not hold the originality.

Both the Dremel 4000 and Dremel 8000, belong to the brand name Dremel and have no other manufacturer. But always make sure to check up on the brand name because fake copies of the product are also available in the market, and they do not perform like the original one and create misunderstanding among the customers.

Dremel is an expert in manufacturing rotary machines and their accessories that provides you the best outcome. Their extraordinary and user-friendly machines also push you towards learning more and being creative throughout your projects.

The companies I’m talking about are not those with which Dremel itself has internal tie-ups. Please note this. This article is a review that is, in fact, based on the original Dremel 4000 and Dremel 8000, and no other versions or doppelgangers.

  • 360-degree Convenient Hold

Tools are often tricky to hold and even trickier to work with. This adds to the frustration of not getting the work done in a jiffy. 

Handling tools that work up on highly functioning motors can even be scary to someone and make them uncomfortable. Users usually have to get used to all these fuss.

But do not worry, these rotary machines are equipped with a 360-degree convenient hold, which is very helpful to deal with a lot of difficulties that you might face. Both Dremel 4000 and 8000 have none of the disadvantages that you have read above. 

Designed with the 360-degree grip zone with a soft grip for comfort and control, it gives you ease in handling, so that you can do your job being free of frustration.

Which one is Better and Why?

We are a little biased towards Dremel 8000 because of its advanced attributes that could take over a lot of problems and deal with some difficulties we might face while managing the project. Let’s hop into the detailed explanation:

  • Accessories available

The Dremel 4000 kit does not have a specific glass-cutting accessory tool. But not to worry; you can always buy a separate specific glass-cutting accessory tool from Dremel itself to avoid delays in the work schedule.

Dremel 8000, on the other hand, has 40 accessories which are still less than the first sub of 4000, but you can always buy extra accessories. It is available in the store. 

The other version of 8000 has no accessories because it is sold separately and has a lot of other specifications that might help you to be on the brighter side while choosing this.

  • Compatibility

If you think that it is more affordable than other models, it may be less functional performance-wise, then your assumption is wrong. Dremel 8000 is great for precision, pressure, and tip. Hence, low cost does not automatically mean low efficiency.

The fact that Dremel 8000 is cordless makes it big in the power tools, especially among the rotary tools. 

The constant twisting and needing to twirl it around every few minutes to avoid breaking the cord from the middle is an unyielding redundant action. Cordless makes it painless, using it at any length or distance.

  • Dremel 8000 is light in weight, so this solves your shaky hands’ problems. Now for an added advantage, it is the fact that you can use Dremel 8000 one-handedly, without fearing to drop or making a wrong cut. A win-win situation.
  • Dremel 4000 leans more towards orthodox functioning. The high-pitched grilling sound ignites the passion for doing your work in the best manner possible. With its innumerable accessories, the extra aid will indeed help you.
  • Charging and use

An LED battery indicator is one of its many pros. The Dremel 8000 comes with a three-light blinking signal that reminds you that your tool is in need of some glucose. 

If the machine ran out of battery and if it needed to be recharged, the LED lights would indicate, and yes, now you have to wait and recharge it. You can always put it on charge before they use it so that you will not have to charge it in the middle of your job.

Remember that the charging time is three hours, much less in comparison to other company tools. A lunch break with a short nap, and you are ready to get back to work with a fully charged Dremel 8000 at its highest capacity. 

But, it could be too much time for some people out there. You do not have to worry about that too, just go with the Dremel 4000 which is corded.

You may encounter some malfunctioning with the battery when you use it for the first time. Not to worry! Check the charging and also the current input, if it’s right or not. If you still face any problem, then you could contact the customer service.

Dremel 4000 works on 120/240V. Other voltage numbers are available according to the place you live in. If you are in a different country, then you will need to buy either a different model which supports your place’s volt or buy a convertible adapter to use the available ones. 

We hope that it is clear that Dremel is a USA-based company, but if you are gonna buy it to use it in a different country then you might have to look upon all the voltage things.

FAQs (Frequently Asked Questions)

  • What is a Dremel 4000 Used for?

    There are a lot of ‘ing’ functions it performs. The list goes like – carving, engraving, cutting, cleaning, polishing, grinding, sharpening, and sanding.

    Among these, there are sub-divisible functions that you can also perform. However, the accessory tools used will vary, be different, and not be included in the kit. Separate purchases will need to be done.

  • How many Amps is Dremel 4000?

    1.6 Amps is the current utilization of Dremel 4000. Compared to other similar rotary tools, using 1.6 amps is very apt for the amount of function it performs, implying less current and more work is the equation.

  • Is Dremel 4000 Loud?

    A simple answer would be yes. But, it is also essential to understand the reason behind why it is so. Since, unlike the battery working model of Dremel 8000, the mechanism of working in Dremel 4000 is ball-bearing-motor-brush involving, it is natural that it produces a loud noise.

So, if you have low tolerance levels, then, by all means, you are free to buy Dremel 8000 instead of Dremel 4000, but remember the difference in features also when making the swap.

Things to Keep in Mind before buying a Rotary Tool

  • Durability: A two-year guarantee like the Dremel 3000 and 7760 is feasible. But before the guarantee card is to be focused upon,  the material used in the making should hold to its name.

No doubt, the conditions on how you use and handle/store the device influence the durability, but its natural ability must hold true to its promise.

  • Power Point: Two types of power sources are identified and functional. They are corded and cordless. The Dremel 3000 and 7760 are corded and cordless, respectively. Similarly, the other models also have divisions of such type. 

Therefore, look at the one according to your choice, whether you want to go wired or wireless.

  • Motor or Battery: Different versions have varied running types. One may use a motor, such as the Dremel 3000, that works on a ball-bearing mechanism, while the Dremel 7760 uses a rechargeable battery.

Also, the motor and battery use different voltages too. To avoid any short circuit incidents, it is crucial to look for the current source the device works on and the one you have at your place.

Only when both are compatible must you go ahead with the purchase.

  • Accessories Count: When buying a Dremel, you will have various accessory number options with different rotary tools. A primitive, simple model may have fewer accessory tools, for example, 10.

An advanced, more high-value function will have more accessory tools, for instance, more than 25. So depending on the range gap, look at your requirement; if you want multiple supportive tools, a minimum set will be enough.

  • Weight: Long hours are required, and your hand has practically paralyzed; not a great working condition to be in. Weight matters in tool handling.

Yes, a heavy-duty rotary tool will naturally have a heavier hold, but it must be so performance-wise too. Otherwise, the pain isn’t worth it. 

And if the tool is lightweight, it is easy to handle and should not fall short of its performance. A balance between the two is the solution.

  • Alignment: Spending bags of money to get a rotary tool, only to discover that the alignment is messed up. Every time you drill into a surface, the hole formed is an inch or a cm above/below/left/right from the marked point.

Hence, alignment is mandatory to be precise and accurate. No mm differences should be detected.

  • Grip: The hold over a tool is as important as the working of it. If it keeps slipping from your hand each time you hold it, then no matter how fast or perfect the performance, you will not be able to see it practically.

Thus, the grip must be solid and sturdy, preferably made of rubber for better grasp and clutch.

Final Verdict

All in all, the final decision is definitely yours to take. So, my strong recommendation would be to weigh and look at all your choices, work out the thought process as far as possible in your imagination, and then take the final plunge. 

There are both advantages and disadvantages for both of these products like the corded and cordless, power, cost, and proportion, etc. All these need to be properly checked and analyzed so that you would buy the best that suits your work style.

I hope that you like the article Dremel 4000 vs 8000, and it would have helped you in every way possible. We would still recommend Dremel 8000 based on all the specifications discussed above, the rest is up to you. All the best and happy tooling!
