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.

Nightmare of a purchase i bought the item in the picture dremel 4000 instead i recieved a worthless dremel 8100 which is battery operated and useless to me. You would think an easy replace or return right. Wrong! I call i get run around they try to plea bargen me into taking the 8100 and a discount off my purchase! Of course i refuse so they switch me back from hold to hanging up on me cause i wouldnt take the item. Call back go through the same get told to go to the store and then a silent hold and hung up on! I go to the store and they cant process a refund off the bar code! I get a manager she cant process the return cause the barcode return label wont scan. She calls up the phone people gets knowhere they ask to talk to me and go throug the same thing apologize say they will refund ask again if i want to take the lesser item then whem i decline yet again they apologize ask to talk to the manager to process the refund put her on hold and hung up on her! Then she tells me i have to come back to talk to some primary manager who isnt here. unbelievable!! Once i get the money that i have in points from sears because i made the mistake of purchasing a washer and dryer from i will never be a customer of sears again!! I spent hours on the phone and in the stores to get a refund for something they sent me that wasnt what i bought! Ive been told thats illegal sears should be charged i would press charges if this were the case i spent so much time just to get a refund for my purchase i wish i could file charges or sue!! I would in a heartbeat! Thats not even the end of it ordered two more items with the points that were returned from this finally by the manager and guess what. I go to pick up the item and they boxed a different items than what was on the box as a referb and tried to give it to me thankfully the employee noticed it just before handing it to me so now im waiting for the return of the points of that items still havent showed in my act that was 2 days ago i cant believe this ****!

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.

Powerful, versatile and comes with enough attachments to do a myriad of tas


Bought this Dremel to replace an older model that I've had for over 20 years (nothing wrong with the older one but got a good deal on the new one and can never have enough tools!)
