At first glance - the 4200 is a very good deal, taken into consideration all the items that are included with the kit compared to individual cost of each included accessories.

Unfortunately - in actual real world use - the EZ Change system proves to be the the weakest point of the design.

Product Features

Most powerful and versatile rotary tool in the Dremel line ( TRUE - but not by much, only 5,000RPM / 30 to 35K difference)

EZ Change system-change all Dremel accessories without the wrench or collet lock (not TRUE, in fact, you need 4 sizes of collets (Dremel 4485) / and the worst part, you need a long nose plair to change them which completely defeats the purpose)

Cooler running with 20-percent more air flow in venting design (YES- TRUE, but i dont like it, when i set the unit to max power, its like a blower and the air is vented underneath)

Variable speed of 5,000 - 35,000 RPM with electronic feedback (TRUE - but not all attachments can be used at 35,000; in real world use, mostly- you will be using 15-25,000RPM)

Includes 6 attachments and 40 accessories for maximum versatility (NOT TRUE - this is very misleading - when they say 40, they are actually counting each individual item, like 4 sanding wheels, 6 cutting wheels, 2 brushes, 4 buffers, etc.) - also, the nomenclature included with my 4200 unit was wrong - it listed all the accessories of DREMEL but the 4200 was not listed (what the hell)

~ Also, the DREMEL 4486 Chuck will not work on the EZ change and so far to date - they are not offering any connector/attachment to let you use it.

If you plan to buy this - IMHO - you are better off buying the Dremel 4000-6/50 or any 4000 series combos.

Size: 47-Piece Vine Customer Review of Free Product ( What's this? )
I use Dremel rotary tool and scroll saw for hobby work and not household jobs. Only reason I don't use Dremel Rotary tool for larger jobs around the house is that I have other power tools for that kind of work and I like to keep my model building tools separate.

Glad to review this latest 4200 version of the Dremel Rotary tool as I hope it will replace my old 380 model that has lasted me a very long time....

If I want to drill any holes other than 1/8" diameter I'll either have to use my Flexible Shaft accessory #225 or my old Dremel tool to do it as this new unit out of the box will only use 1/8" shanks in the EZ change chuck and no way to use my old collets to change sizes as they are different and will not fit.

Dremel shows that they have collets for smaller bits available for the 4200 so will have to buy those separate. Don't see a "set" available. Really seems they should have included the collet set with this tool.

EZC481 3/32" Collet
EZC482 1/16" Collet
EZC483 1/32" Collet

Included with the tool is the EZC480 1/8" Collet

Need to use needle nose pliers to compress the three ears of the collet some, hold the regular EZ change levers down and then pull collet out of the 4200 EZ change head. Collets can be pushed back into place while holding the EZ change levers down while doing it.
A bit of a pain when you are used to the old way, (unscrew end and collets fall out) but hope to get used to new way as I always use several sizes smaller doing precision detail work at slower speeds.

I do like the keyless locking system they added to this one , very stout spring inside requires that you pull levers on both sides at once to change bits.

the ez change collet is a great idea, BUT it only works on one size (1/8") bits. when i bought mine, the tech service promised me the other collets would be out by march. he even gave me the item numbers ezc481 and ezc482, so i could finally use my 3/32 and 1/16" bits.

i searched and waited and finally called back again today. they told me they are not making the collet, and have no plans to at this time. she reccomended i buy one of any other tool they sell, since all the others work with multiple bits.

this is ridiculous. they market this as an improvement, then after you buy it, after you are past your 30day return period, they tell you that it wont work after all, the way the promised.

the only possibility is ordering a different collet for the flex shaft, replacing it, and using the shaft each time. however, now you completely defeat the quick change option that is the reason people are buying this in the first place.

someone really dropped the ball.

of course, otherwise, this is a decent tool. like most tools this size, it doesnt have the power to do everything it claims to do... at least not in a decent time frame. if you only one to use 1 size bit, and you want all the contraptions (though i doubt anyone will), this may be a decent buy. not for me.

I've been a Dremel rotary tool user for over 20 years. As a general hobbyist, I'm very pleased with Dremel tools. When my old rotary tool finally wore out (in the middle of the Pinewood Derby season), I opted to upgrade to the 4200. The 4200 is noticeably larger than my old Dremel. But it doesn't get in the way. The best feature of the 4200 is the EZ Change feature. No more need for the small bit wrench, and switching bits is super fast. All the accessories that comes in this set is also a big plus.

Warning though, I guess they don't make 'em like they used to. On 6/17/13, I was unable to remove the circle cutting attachment from the threaded collar. The threaded collar somehow managed to become loose from the housing and now spins freely, thus preventing removal of the attachment. I called it in to customer service, and they were great about it. I referenced diagrams in the user manual to explain the problem, and they understood right away my dilemma. 5 stars for customer service. I am currently waiting for my replacement unit as I send in the broken one. I would probably rate this a 1 star for the quick tool failure. But the customer service outshines the material defect. Way to go, Dremel!

I will update once I receive the new or repaired unit.
