Abstract
A power tool includes a motor; an arbor attachment mechanism that includes a shaft configured to be driven by the motor about a spin axis. The arbor attachment mechanism is configured to hold a blade onto the shaft. The power tool includes a blade size limiter that is configured to prevent attachment of a blade with a radius greater than a predetermined size, and is configured to be connected to the arbor attachment mechanism independently of the attachment of the blade to the arbor attachment mechanism and such that the blade size limiter is at a distance from the spin axis of the shaft.
