You guys are scaring me.  I have a Dremel model 270 that I bought in the late 60's.  I have used it for just about everything possible and it is still going strong.  I hope mine never breaks.

Just broke the flexible coupling on my 20+ year old model 396 and so have ordered a new coupling.

Would there be any benefit to put heatshrink on the new coupling, my reasoning being that if it broke again would at least hold it place.

Thanks great thread!

A new use for my Dremel Tool. Last year my regular doctor told me to see a specialist for the foot pain I had reported. My doctor thought it might be a bone spur. The foot doctor X-rayed everything and concluded I just had a build up of callus. He worked it over with a scalpel and then dressed it further using a Dremel Tool with a drum sander, same as I have at home.

In my experience heat shrink tubing is not very fexible, especially after being heated. If the original flex coupler lasted for 20+ years, I would not try to improve on it.

Thanks did not know that heat shrink was not flexible

Hi Guys, I have a Dremel Moto tool 300 series which has a blown commutator. The tool is only about 7 years old and according to the guarantee blurb, we only get a 5 year guarantee. True or false?

Talk to Dremel. All you can do is ask. Sometimes a company will stand by thier product. You will have to ask and see.

Let a buddy use mine and he overstressed it and blew the coupling. Ordered a replacement but got impatient and went to the local hardware. Sized up the broken coupling with 1/4" clear tube and it worked. Still using it that way. The replacement is still hanging with my dremel bit set. That was about a year and a half ago.

My coupler broke (like all the others). I reversed it and slid it down farther ... broke again after a few uses. Now a few years later my other Dremel tool coupler also disintegrated. You can't buy these parts locally and I was "ticked off" that they cost $6.99 plus shipping or $25+ bucks for a 5 pack so down to my basement to make my own from whatever was lying around. I have an assortment of tubing types and found one about right size (1/4" diameter) cut off to 1.25" length and it works great! I used a tube thats pliable but something firmer may be better? Repaired my second unit and it works great also. Like this a lot better than feeding the parts supply chain and it really ticks me off that Dremel (Bosch) doesn't sell parts or that it would cost as much as $25 to fix something for an $0.10 part. I will NEVER buy another Dremel product in protest (unless I need one LOL). BTW all the Dremel "accessories" are also outrageously expensive. Handy tool though, glad I have two that will now last me the rest of my life since I now have a bin with a bunch of couplers ready to go when I need one!

I have a very old variable speed model. The coupler is the weak spot. I ordered a few couplers years ago to have a spare on hand. Well the tool coupler gave out and the spares became brittle over time and useless. So I too went the tubing route. This was quite a few years ago. Still going strong but now I get a slight vibration until it gets up to max speed. Once it gets to top speed it is super smooth. I need to open it up for a look see. A very handy tool. I use it often.
