The Dremel 3000 VS 4000: The Devils in the Details

Now that you see all these 2 have in common, it’s time to take a closer look at what sets them apart. There are 3 main differences between them, which we’ll examine by category to make it easier.


The 3000 and 4000 both have variable speed control, but the 4000 takes it a step further with a separate on/off speed dial to control it. The ability to switch speeds instantly and without interfering with a project gives the 4000 a distinct advantage. You can speed up or slow down mid cut, elevating designs and finishes to a professional level. Those who do delicate etchings or complicated swirls and woodwork will appreciate the added control.

Electronic Feedback

With the 3000 you need to use your judgment when it comes to the right speeds and pressures, which may cause a few mistakes for newbies. The 4000 eliminates this issue by providing electronic feedback as you work. It will let you know when your speed is off or you’re grinding too hard, for improved craftsmanship. Makes it more friendly for beginners and gives a higher level of control and manipulation. For instance, if you’re new to using a rotary tool and want to buff some old family heirlooms, the feedback function will help you to do it right and not wear out the piece.

Motor Size

The 4000 has a larger motor, 1.6 versus 1.2 on the 3000, giving you greater range in your work. You can work with more materials and mediums without sacrificing comfort since the 4000 is still pretty lightweight. For those who need to cut through dense materials, or want to do bigger projects, the added power will be a big help and eliminate the need for additional tools.

Rotary Tool DIY Projects

For those planning to buy one of these machines, here is a fun project you can use it on, courtesy of Dremel.

Homework Tool Box

Cute and pretty easy, you can use the Dremel 3000 or 4000 to make this homework organizer. Here’s how:

Materials/Tools: Dremel 3000 or 4000; Dremel Saw-Max; various paints, small wood boards, nails, dowel.


Start by cutting out the sides and bottom of the kit using the Dremel Saw-Max and the SM500 Wood & Plastic Wheel. You need 5 pieces in all, here are the measurements:• Bottom: 12″ by 4″ • 2 Long Sides: 10 1/2″ by 4 1/2″ • 2 Short Sides: 8″ by 6″.

Next, cut the top corners of the 2 short side pieces at an angle. Draw the angle lines by marking an inch and 1/4′ in from either side on top; make a small mark 4 1/2″ from the bottom. Then, join the top marks to the bottom mark and cut using the SM500 Wood & Plastic Wheel.

When you’re done cutting, nail the sides together; you can use wood glue before nailing the sides if you want added support. Then, pre-drill holes for your handle in the top of the side panels using the Dremel 3000 or 4000.

Next, take your dowel and cut it to 12′ to make the handle and attach it. Finally, paint whatever colors you like, and you’re all set!

After comparing the Dremel 3000 versus the Dremel 4000, it’s pretty clear that both these machines are a great addition to any professional or beginners toolbox. Both models deliver in terms of quality and efficiency, with the 4000 being a slightly better value for your money thanks to its upgraded motor and improved technology.

It comes down to your personal preference and the projects you plan to do. Just know that whichever one you choose, MacGyver is just a show- so choose your projects wisely!
