Dremel 3000 vs 4000 – Which one is better?

Dremel 3000 vs 4000 – Which one is better?

If you are confused between the Dremel 3000 and the Dremel 4000, you have good reason to be. Both are extremely popular, great quality tools that do many of the same things and even sell at prices that are not too different from each other. So, what exactly is the difference between Dremel 3000 and 4000? That’s what this post will discuss. By the time you are done reading this post, you will have a better idea of which one of these Dremel tools will make sense in your garage.

Let’s quickly get down to the most important differences between the two.

 

The motor

The Dremel 4000 uses a 1.6 amps motor that is also used in the higher end Dremel 4200 rotary tool. The 3,000 series uses the older 1.2 amps motor. While 1.2 amps is still plenty of power to get most grinding, cutting, cleaning and sanding jobs done, a 1.6 amps motor is simply more powerful. Both motors have a commonality in the fact that they are both variable speed motors. Speaking of variable speed brings us to the next difference between these two popular Dremel tools, discussed below.

Variable Speed

The Dremel 4000 has an adjustable RPM range between 5,000 and 35,000 while the Dremel 3000 has an adjustable RPM range of 5,000 to 32,000. The difference isn’t all that much on the higher end. But, it can make a difference for a few people who need very specific speeds for certain tasks.

However, most grinding, cutting and sanding tasks are best performed at about 20,000 RPM. 20,000 RPM is considered the sweet spot for any rotary tool.

Variable Speed Adjustment

Both the Dremel 3000 and the 4000 allow for variable speed adjustments. But, the Dremel 4000 lets you fine tune RPM to an exact level that you need while the 3000 lets you choose between pre-set variable speeds.

In other words, it might be possible for you to exactly select 23,000 RPM on a Dremel 4000 while you can only jump from 22,000 to 24,000 RPM on a Dremel 3000, without being able to specifically apply a 23,000 RPM setting. Again, this is a rather small gripe for the 3000 but it might be of significance to some people.

Feedback control for consistent speeds

The Dremel 4000 features feedback control. What this essentially means is that the motor can work a little harder or lesser to give you accurate RPM based on the feedback of the drill. In other words, if the motor is set to run at 20,000 but the pressure you are applying is making the motor vibrate and under-perform, the circuity is smart enough to ramp up the RPM just a little, so you can work at a true 20,000 RPM.

The Dremel 3000 does not have this feature.

Number of attachments

The Dremel 4000 comes with 4 different attachments. They are as follows; a multipurpose guide for cutting, a sanding/grinding guide, a circle cutter (also known as a straight edge guide) and a handle or grip that allows for detailed workmanship.

The Dremel 3000 on the other hand comes with only a sanding/grinding guide and a cutting guide.

Please note that Dremel attachments are sold separately and that attachments bought from Dremel will fit on both the 3000 as well as the 4000. However, there are some high-performance attachments that will only fit on the Dremel 4000 and not on the Dremel 3000. So, if you have a particular attachment in mind that you want to use on these two tools, we suggest that you look up Dremel’s website specs to see if it will fit on the 3000 as well as the 4000. With the 4000, you can be assured that it will fit whereas there is a chance it may not be feasible with the 3000.

Number of accessories

Now, please note that both the Dremel 3000 and the Dremel 4000 are sold in differently priced kits that come with a different number of accessories. For the sake of comparison, we will only compare the basic kits that these rotary tools are sold with.

The Dremel 4000 comes with a 34 accessory kit with the following breakup; 2 engraving accessories, 6 cutting accessories, 4 grinding/sharpening accessories, 6 cleaning and polishing accessories, 12 sanding accessories and 5 miscellaneous accessories like a mandrel, wrench and nose cap.

The Dremel 3000 comes with a 28 count accessory kit that feature the following; 3 accessories for cutting, 4 sharpening and grinding accessories, 8 cleaning/polishing accessories, 6 accessories for sanding purposes and 4 miscellaneous parts like screw mandrels and a wrench.

As you can see, the Dremel 4000 gives you a lot more sanding options than the Dremel 3000. On the other hand, the Dremel 3000 gives you more polishing options. Of course, all this is irrelevant if you can buy the accessories separately. Based on what you will use the rotary tool for, the Dremel 3000 vs 4000 decision will come down to your personal preference.

That’s all for the differences in this Dremel 4000 or 3000 post. Now, let’s look at prominent features that both these great tools have in common.

EZ Twist system for quick accessory changes

Both the Dremel 3000 and 4000 use the Dremel EZ Twist system, which features a nose cap that can be unscrewed and used like a collet spanner. The idea here is to eliminate the use of a spanner that can break your workflow and creativity.

You just unscrew the nose cap, push it up to the collet and then tighten the collet and drop it back down as screw it back on as a nose cap. It works pretty well once you figure it out. With this system, it will take you about 5 seconds to swap out an accessory. If you have used a rotary tool without such a feature, you know how it can easily take you at least about a minute to remove an accessory and put a new one back one.

Great for multiple uses

Both the Dremel 3000 and 4000 will satisfy most of your carving, cutting, cleaning, polishing and sanding, sharpening and grinding needs. Dremel sells a whole host of accessories with very specific purposes and chances are that both the 3000 and 4000 are equipped for any rotary saw task, if equipped with the right accessory.

You might find the accessory in the kit that came with the Dremel tool. If not, you can always buy it separately as and when you need it. Dremel’s designs allows for the 4000’s accessories to be used on the 3000 and vice versa, thus making that angle of your buying decision easier to analyze.

So, if you think the 3000 will be good for you but are worried about one task it does not perform out of the box, chances are that an accessory will negate that shortcoming.

So, which one should you choose between Dremel 4000 Vs 3000?

Now that you know what each tool can do and cannot do, it will all boil down to what you are looking for in a rotary tool and how much you want to pay for it.

If you can afford it, the Dremel 4000 is a no brainer as it does all the things than the 3000 does, and then some. But then, if you are in need of a basic rotary saw that still gives you high end performance, without some bells and whistles, the Dremel 3000 is still an excellent choice. There is a reason why it continues to still sell very strongly, despite 4000 and the 4200 replacing it several years ago. And like mentioned before, the 3000 can always be made more useful by buying more accessories and attachments, should the need arise.

Arguments for the 4000 are that it is has a more powerful motor and a more precise variable speed control. Another big difference is the feedback mechanism in the 4000 that will give you as close an RPM as you set, while the 3000 will work at RPM that will not always be true to your setting, depending on impact feedback.

Another point to note is that the Dremel 4000 is sold in more kit variations than the 3000. The 4000 is sold in 28, 34, 30 and 50 piece kits, at very competitive price points. Depending on your needs, you might be able to pick up a kit with accessories enough to last you a very long time. Buying something like the Dremel 4000 with the 50 piece kit can help you save money if you total all the separate costs for accessories. For example, the Dremel 4000 with the 50 piece accessory kit includes the flex-shaft attachment that alone sells for about $25. The 3000 has kit choices as well, but you only have two kit options to choose from. One is a 24 piece kit and the other is a 28 piece kit.

They both come in a nice carrying case, with a 6.5’ corded power cable and a retractable metal clip for easy hanging. Both tools are solidly made, with enough rubber padding to dampen vibrations and give you a tool that feels great in your hands.
