A step by step instruction on how to replace/fix the coupling on a Dremel Moto Tool Drill model #395.
The rubber/plastic coupling links the motor drive shaft to the drill spindle. This piece will flex and over time disintegrate and fail, or when the drill is under extreme stress the coupling will "break out" protecting the motor.
It's an easy DIY project to replace the coupling (part # 2615294309). This part is now made by Bosch which now owns Dremel and can be ordered online.
