Abstract: A power tool and an accessory mount device are provided. The device includes a driven member, a plate, and a flyweight comprising a first flyweight portion configured to translate along the first direction and contact the plate. The flyweight includes a second flyweight portion configured to translate along the second direction. The flyweight is positioned at a hinge between the first flyweight portion and the second flyweight portion and is configured to rotate along the hinge to push the first flyweight portion to the plate and translate the plate and the driven member along the first direction toward the first end when a rotational speed threshold about the first axis is exceeded.
