Introduction
The shaft lock assembly is a locking mechanism that allows the Dremel bit to be replaced. The assembly holds the motor shaft in place when the shaft lock button is pressed, which stops the shaft from spinning and lets the bit be removed by hand. When the shaft lock assembly is damaged (commonly from the Dremel being dropped), the shaft lock button may no longer work properly.

Battery
