Many people may be wondering if they should get Dremel 4000 for their holiday gifts and have been looking for detailed reviews so here is my contribution.

I received my Dremel 4000 a month ago and so far used it for moderate work with cutting and shaping sheet metal (soup cans etc) and very light work with drilling and shaping plastic. So far it's been working great. 4000 works fine with all the speed setting as they advertise. It seems like they solved the problem with the lower speed setting. The speed changes in a little increments rather than smooth transitions. In a way, it feels a bit like digital but I see no problem here.

My only complaint is its size and weight. Probably it's OK for rough work but for detailed work it strains my hand after some time (my hands are small). It probably makes sense to invest on flex shaft and foot pedal if you are going to do a lot of detail work with this machine. The engraver's handle that comes with this particular set adds more grip options but it's a bit flimsy so it's only good for very light work.

4000 is a really big machine. It's thicker than XPR and way longer than any previous models I've seen. Probably the speed feedback circuitry and new cooling system required this added size. The balance is quite a bit awkward when I hold the machine like a pen to do detail work. The engraver's handle does not really solve the bad balance either.

In the higher speed, it is quite loud. It gives off high pitch sound like you are in dentist's office even without any tool attached on it. I can stand it but for some people it can be quite annoying. I recommend having earplugs handy. It also blows a lot of air from the vents- I guess it's a good thing for keeping the motor cool.

I have used Dremel tools for more than 10 years. I have never used any other rotary tool, as I have never had any major issues with Dremel. Below, I will provide some pros and cons, based some experiences I've had with different types of work (only things I've done with the 4000 model). When I say attachment, I mean the pieces you attach to the tool itself. When I say accessories, I mean the bits you insert in the top of the tool (drills, discs etc). Just to clarify.

First, I got the Dremel 4000-5/36 kit from Home Depot and then ordered some extra attachments and accessories from Amazon.

From personal experience, I can tell you right away, get the flex shaft attachment. It will make everything easier. Almost everything you can do with the rotary tool itself, you can do with the flex shaft, only more precise. Plus, it is much easier on wrist and hands. Be sure to check regularly if it needs lube though, if you use the tool a lot.

The rotary tool itself
- Very, very versatile tool. Can handle many different types of jobs around the house.
- Works just as well for many types of hobbies. Such as carving, engraving, jewelry making and much more.
- The rotary tool is very well built and durable. No issues after 6 months of continuous use for me.
- The speed is variable. From 5000rpm up to 35000rpm. You can adjust speed by 1000rpm at a time, giving you 31 different speeds. Great since all jobs require different speeds. DO YOUR RESEARCH ON THIS SUBJECT! Don't ruin your accessories or material by using to high or low speeds on some projects.
- Has lots of ventilation, keeping it cooler.

My old dremel finally bit the dust after 30 years of service so I needed a new one. After reading some of the negative comments I was a bit worried about this one, but decided that I would give Dremel my business again since the last one had last so long. I also wanted the flex shaft attachment and the right angle attachment [and that German unit did NOT have a right angle attachment for sale and people really trashed their flex shaft attachment]. Well, so far so good. It is actually quieter then my old one, and I have already used and fallen in love with the right angle attachment - wished I had bought one years ago]. I also wonder how many people that complained about the flex shaft did not run it for two minutes in a vertical configuration before usage each time? Manual says to do that and it helps to work the storage kinks out of it and likely keeps it running cooler with less issues. And the case was built to hold all of that stuff, so I now have it consolidated into one box, even with all my old parts.

Dremel has a keeper here. Oh, and I use mine for making fine details in hard wood, cutting tiles and metal, cutting the occasional lock that has lost its key... etc. A little bit of everything which is what these things can do.

This thing has so many uses, and is powerful and reliable. You might see some competitor's products at lower prices, but they just aren't worth it when you compare the power, versatility and reliability of the Dremel. The RPM range is quite large, and even the side handle is engineered smartly with a ventilation channel to allow for cooling. Case is very handy and has several slots for various items and attachments/bits. Even the cord snaps in to the case. You can put the tool away with most accessories on it and not worry about the case not closing.

Also, for most accessories you don't need to mess with the little wrench to tighten them, there is the quick tool already installed on the dremel at all times, you just loosen it, and there's your tightening wrench :)
