Claim:
An arbor assembly for connecting a cutting tool to a power tool, the arbor assembly comprising: a shaft defining a longitudinal axis and including an end portion configured to couple to the cutting tool; a plate surrounding a portion of the shaft adjacent to the end portion, the plate having a first surface configured to engage the cutting tool when the cutting tool is coupled to the shaft and a second surface substantially opposite the first surface, the plate movable along the longitudinal axis relative to the shaft; and a wedge member positioned adjacent to the second surface of the plate and defining an opening to receive a portion of the shaft, at least a portion of the wedge member being tapered such that a thickness of the wedge member decreases from a first end to a second end, the wedge member movable relative to the plate from a first position, in which the plate is inhibited from moving along the longitudinal axis away from the end portion, to a second position, in which the plate is movable along the longitudinal axis away from the end portion.
