Abstract
An arbor for a hole saw an arbor stem, an actuator, and at least one post. The arbor stem includes at least one arm having a threaded portion configured to engage the hole saw. The actuator is rotatable about a central axis of the arbor to move the at least one arm. The actuator includes a surface facing the at least one arm and a track. The track is recessed from the surface of the actuator. The at least one post extends from the at least one arm to engage the track. The arm is movable in a radial direction in response to rotation of the actuator to vary a circumference of the arbor stem.
