 Yes, unlike so many items we buy today, Dremels are fixable. And still not horribly expensive. If you have a broken one, fix it, don't toss it. Too often that's not an option these days.

HOLY MACKEREL;  yours truly has TWO Dremel 395s, which bit the dust over the years!  Better take down those 800 numbers, get busy and get 'em fixed! THANKS SO MUCH for this very timely post! TTFN....Old Tom aka papasmurf in NH

  A few years ago I needed a part for my Model 2 (a 1956 model) .  Called Dremel and the nice young lady I spoke to said that this part was no longer in stock and had not been for some time.  I asked if by chance there was an old guy there, who had been there  forever, that might know.  On hold for a couple of minutes, when she came back on, they had found the part I needed.  It was the very last one.  Asked for the price with shipping and was told there would be no charge.  Whoever she asked had enjoyed using their knowledge, instead of what as on screen.   Sometimes you just have to ask the right questions.    I have had other dealings with Dremel and they are just  a great company to deal with.    Steve

Hi!

Dremel is one of those companies that puts out a solid, reliable, useful product and stands behind them providing readily available parts and service.   

I have a corded one purchased in the late '70s that has seen heavy use and still working just fine.   I also bought a cordless one (w/ extra battery) that has proved to be even more useful.

 

ENJOY  !

I had one which was probably 10 years old go bad on me, sparks happened inside and it quit.  I sent it in and they repaired it free of charge.  It has worked ever since - variable speen type.  Must be they have a long or life time warranty.

 Probably wore the brushes completely out if you had it 10 years and used it a lot. Last little nub got sucked out of the brush holder, spring followed, shorted - sparks. Glad to hear they fixed you right up. I've always felt Dremel tools were a quality and worth the extra over a 'generic' version and this thread only reinforces that.

It had the *poof* problem when i was living in Texas around 1985 and I don't think I had had that Dremel more than 4 years by then.  It is coming up on 30 years old and I've used it far more since it had been repaired than prior.  Why it sparked and died is probably not from heavy use.

Dremel motor tool repair - Older Model 395 output nylon coupling
Posted by chutton01 on Wednesday, May 18, 2011 10:03 AM

I am bumping this thread, as I just had an issue w/ my older model 395, that was kind of a pain to find info about (eventually found it on a aircraft modeler site), but which is easy to resolve once you know what to order, so figured I'd share the info.

Inside of an older Model 395, there is a plastic (nylon?) coupling between the motor armature and the output shaft/collet. The idea behind this coupling is that if the output shaft becomes stuck (the grinding wheel or drill bit or whatever), this coupling will twist and shear rather than have the motor stall and spark/melt.  This idea was so good that all later model 395s dispensed with the plastic coupling and have a direct metal shaft between the armature and output (and this configuration is what you will find most exploded view diagrams of the 395 are on the web, which confused the heck out of me at first). 
Of course, being of plastic, eventually the coupling becomes brittle and...well, my Dremel first made an odd rumbling noise, and then the output stopped spinning even while the motor continued to rotate.  Upon taking the Dremel apart (fairly easy, 6 screws altogether), well you get the idea (which was several yellowed nylon spline fragments between the 2 metal shafts)

The part you will need is called a Flex Spline Coupling by the Demel Service center - I contacted the one sort of closer to me: Dremel Service Center: 1-800-437-3635 (Racine, WI) - there is an Authorized Service center in Palm Springs, CA: 1-800-275-2052. Contact info on their website (www.dremel.com)

Couplings are 1.25 apiece, so I ordered a few just in case...

The thing is it hadn't gotten used all that much over that 10 years, I'd used it more since the repair.  Maybe metal shavings got in and shorted something out?  I'll never know but they repaired it free of charge.  Its the older model from the late 70's and still a good work horse.  Hasn't gotten much use in the last 10 years because my layout was torn down when my marriage went *poof*

 I had one go easier then that. Bought one of their kits with all the do dads etc. in it from Home Depot. After a while using it the thing got hotter then a $2.00 pistol and the lock that holds the chuck quit working.

Walked in to HD didn't even have the receipt the nice lady looked said got your receipt , nope took it back no questions asked gave me store credit, walked over and picked up another one a knock on wood haven't had a problem yet. Whole deal took less then 10min.

Just my 2 cents worth, I spent the rest on trains. If you choked a Smurf what color would he turn?

Forgot to mention, you need a T10 Torx to remove four fasteners to open the tool.

 Dremel is a solid company selling a good product line, IMO.

I'm glad you have had good experience with Dremel.  I will keep that in mind for future reference.  I received a Dremel set (Rotory tool, case, and numerous attachments) as a Christmas gift a couple years ago.  I have yet to use it much.

My fifteen year old Dremel tool recently came up with a speed control problem. It is a model 395. I went to the Dremel site and found an 800 number and parts layout with part numbers. They answered rather quickly and I was able to order the replacement speed control for $14.00 and a few dollars for shipping. All well now. Very good service.
