The do it all tool!

I use this Dremel for just about everything. I do custom engraved signs on the side, so the plunge router attachment works great for that, along with the huge selection of different bits to choose from. I use the polishing kits for buffing and polishing small items around the house. The cutoff wheels work great in small tight areas that a normal grinder can't get into. Many other uses too. I like this model with the different speeds so much that I bought a second one. i have hundreds of differnet bits I can use at anytime.

The second time ever using it, the motor blew.

I would think purchasing a new, updated, top of the line Dremel 4000 would be a wise decision and would make a great tool, but I was wrong. The second time EVER using the tool, sparks came out of the back and I quickly shut it off. I tried turning it back on and what do ya know, the motor blew. I was only cutting some wood around nails at medium speed when this happened. I take it back to Sears because there was a warranty on mine and they said I have no records of any purchases what so ever. I've been buying tools from them for how long? They tried to help me but for some reason I have no records of any purchases and Dremel cannot do anything about it. Awesome. Now I just wasted money on a broken tool that I got to use twice. But hey two times is better than none right?

Mixed feelings


I have had a Dremel 395 Type 5 that I have had for a long time. It's really nice as 1. I am a small person, and it is a small and easy to hold tool and 2. There are a lot of house repair and crafty things you can do with it. I still use my 395 a lot, but I needed a Dremel, and it was simply too expensive to get my original Dremel sent to me. (Long story). Anyway, I got this, and had a few of my bits and accessories mailed to me so that I could work on a project.
I feel like my 395 is more stable speed wise when the tool is not under load. Out of the box, the 4000 would pulse somewhat when not under load. Most of that went away after I broke in the brushes (run it for five minutes on maximum speed with no load), but it still does that a little. When under load, however, the 4000 seems to be more stable speed wise. It also seems to have somewhat more torque than the 395 has. That makes it a little easier to control. I really like that the switch and the speed control are separate. I can set the speed and turn it on and off as needed. I also like that the speed control gives an approximate indication of the speed of the tool. All you need to do is multiply the number by 1000 to get the approximate speed. I also like that the switch is right at the head of the tool so that it is easier to turn it on and off. I have mixed feelings about the rubber coating on the body of the tool. The 395 I have does not have that. The rubber coating seems to make the tool easier to grip and dampen some of the vibrations though which is nice. I have mixed feelings about this EZ twist nose cap which has an integrated wrench. I use a keyless chuck on my Dremel, so I can easily change bits. The nose cap cannot loosen or tighten this chuck. You will need the regular wrench for that. The EZ twist nose cap only works with the collet nut. I do like that the new collet nut has four faces to make it easier to use this EZ twist feature, but while I do have a full set of collets, and they can be useful in some circumstances, I don't use them as often because I have the chuck, and when I do use them, I prefer to just use the wrench because I only use collets for more heavy duty work, and I need them to be tighter than the EZ Twist can get them. Also when the EZ Twist is used, it just seems really fiddly. It isn't as positive as the wrench is when it is tightening the collet. It just seems to me to be a kind of gimmicky feature that could be good in an emergency, but kind of clunky in day to day use.

The accessory and bits provided are kind of a fascinating selection. You get a random sampler of cut off wheels, a few small sanding discs which, even years ago, didn't really seem too useful. They are tiny, and they don't do a lot. You might be able to get more done hand sanding than using the little discs. The drum sander is useful, not necessarily for sanding, but for shaping and carving wood and some plastics and metal. There is also a small wire brush which can be very useful, two small grinding stones for sharpening, a cutting bit, and a small cutter. It really is a tiny, but random selection. I'm not entirely sure what the bit kit was made for. I also wonder about the choice of the Fiberglas reinforced cutoff wheels. Those are cutoff wheels I use a lot, but I use the EZ Lock version. The kind provided in the bit kit tend to eat up mandrels for lunch. I went through a number of mandrels until the EZ Lock version came out. As for the accessories, they are quite interesting. There is a circle cutter and sanding/grinding guide. I haven't found so much use for them. They seem kind of niche use accessories. In all the time I have owned a Dremel, I have seen these accessories in the store, but they were never on my list of things to get. My 395 came with a flex shaft, and that was one of my most used accessories. I even got a new one when my original one stopped working properly.

I really like the manual pack that came with this tool. The regular booklet is a lot like the one that came with my 395. I think a lot of the warnings are exactly the same. The quick start type guide was quite nice and eye catching though. It was also easy to read and understand. The manuals for the accessories (circle cutter and sanding/grinding guide) were included too, and that was helpful.

I have mixed feelings about the case. I love how small and compact it is compared to the one that came with my 395. I also love how everything including accessories such as the circle cutter and sanding/grinding guide slots into place and doesn't fall out or move around. There is even a slot for the flex shaft. The case of my 395 has a tray where you can store all your bits. This one doesn't really come with that. This new case can only hold three 1/8 shank bits and one 3/32 shank bit. One thing I like in this new case though is that you can snap in a small case of accessories. They include one of these with it. The small case has partitions, and you can arrange small parts and some bits neatly inside. I would worry about bits hitting each other and getting chipped or dull, but I do like the way the small case holds all the small parts and keeps them organized. The case of my Dremel 395 had a small place on the bit tray where you could put small parts, but if someone bumped into you, the small parts would end up everywhere no matter how neatly you arranged them before closing the case. This small case is so much better for these small parts. I no longer have to worry about random cutoff wheels and sanding bands and disks floating around randomly in my case. I also don't have to find small tins and containers to put them in so that I could put them somewhere so that they wouldn't get lost. One thing I have mixed feeling about the case though is that the case uses living hinges for everything from the two clasps in the front to the hinge on the back. The case for my Dremel 395 has actual hinges made of plastic on the back of the case and clasps that are not hinged, but are springy and don't have to bend like the living hinges do. I wonder if it will last as long as the case for my 395. I don't feel like the living hinges are very confidence inspiring.

In all, this tool seems quite nice. While there are some things that give me mixed feelings, overall, it seems quite good.

Powerful and Compact


When changing the thermostat on my '97 Jeep Grand Cherokee, I broke off one of the bolt heads. After failing to remove the frozen bolt with other drilling solutions, I took the advice of an auto parts dealer and purchased a Dremel and a hard rotary file bit. The slim profile and variable power of the Dremel allowed me to access the bolt and drill the hole needed to successfully remove the bolt. I'm looking forward to using this tool for many other diverse projects. I purchased the corded model to make sure I wouldn't run into any issues with fading battery power. I'm really happy with this product.

have it

Why didn't I buy this sooner?


I am still learning how to use this but I am surprised about how handy this really is. I'm practicing on things so I can become more skilled before I ruin something nice.
