Part #2615294309 - This replaces spare parts 2615302213 and 529430970.

Don’t throw out your Dremel Rotary Tool just yet..... It could be as simple as replacing this coupling that connects the drive shaft to the motor. This part can break when you have loaded the tool up too much and will prevent any serious damage to the shaft or motor. They also become brittle over time after constant wear and tear.

Buy 2 or 3 and always have a spare for many years to come.

Also have you checked your brushes as they could be worn and need replacing as well.
