Exactly what I needed to get my Dremel up and running. Easy to replace and a great price for a pack of 5. If the bit on your Dremel doesn't spin do not throw it out and buy a new one. Open it up by removing the 6 torx screws and check the coupling. Chances are it's broken. Put in a new one and you are good to go. Literally takes less that 5 minutes!

I paid $ 7.47 for one inch off a piece of medical iv tubing that I had a long length of. If you need this just buy a piece of medical IV tubing and cut off a piece the size you need.

These look to be better material than the original. I use this with 1" cutoff wheels on steel. which puts a lot of strain on the coupling. My great grandchildren will probably have a few spares when they inherit my tools!

These Bosch branded parts fit my Dremel perfectly - they give a slight press fit and the length is right on.

This is the one part that seems to fail after a few years service. Wish that it was made of more durable material. Guess that it is supposed to keep one from "burning up" the motor with extended periods of continuous heavy usage. Glad that are four extra couplers in the package.
