Dremel trio stop work completely dead

SOURCE: Dremel 395 won't turn on

I have a Dremel 395 Type 3. Motor works fine, shaft doesn't turn. Took it apart to find that the white plastic or nylon flex coupling on the shaft had crumbled and the spline driver, which fits directly over the motor end of the shaft was somewhat worn. I emailed Dremel and got an overnight reply listing the 2 parts I need and the cost: Coupling is $1.00 and the driver is $1.25. Placed order by phone: 1-800-437-3635. I ordered 2 of each in case future replacement is needed. Total bill came to $7.27 including Florida tax and shipping. Can't beat that. They said it would be in the mail by tonight. (Flex coupling number is 2615294309; spline driver is 2615294308.)

I have exactly the same unit a 395. The kit comes w/ a wrench to unscrew the nut holding whatever you have locked in. If you can't find the wrench then I suggest you get an adjustable wrench and lock it into the flat side of the nut. There is a place where it will lock in so that you can tighten or loosen the nut. Some of the 395's come as a kit w/ all the different attachments, accessories, heads and tools. If it came with a plastic case the wrench is usually slotted running parallel just in front of the handle. You will see it when you open the case and take a top view look at the handle. It is sometime hard to see but it's just there. Good luck.

SOURCE: My Dremel tool motor still works but shaft won't turn?

Here's the email from I got from Dremel (in my case the flex coupling broke):
Inside the tool is a flex coupling and spline driver.

The flex coupling is # 2615294309 and the price is $ 1.25.
This is the hollow plastic sleeve about 1" long with grooves on the
inside, that goes between the motor shaft and the output shaft.

The spline driver is # 2615294308 at $ 1.00.
Spline driver sits on the direct end of the motor shaft. The flex
coupling sits over the spline driver. Spline driver is about 1/4",
hard plastic with grooves on the outside.


Total shipping for orders under $ 5.00 is $ 2.50. Orders over $
5.00 is $ 4.00.
