Drywall dust has ruined your tool. It seizes up bearings and bushings like you wouldn't believe.

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.

My 15 year old Dremel 395 had the same problem so I took it apart. There is a plastic spline between the motor and the output shaft to the chuck . My plastic spline was split and had many of its teeth sheared off. The shaft lock acts on the output shaft side of this spline, so it was ok. Otherwise everything looked great; bearings ran free & had little play free, brushes ok. To be fair, my Dremel had seen hard use & doesn't owe me anything. No luck so far finding replacement spline parts, which if available should be easy to install. To take apart your tool, just google "Dremel Disassembly". GOOD LUCK!

You can either go to Dremel.com and type in your model number for replacement parts or call their toll free number at 1-800-437-3635 and get that information. Let me know if you need anything further
