A cutting tool clamp mechanism for a power tool includes a housing supported by a spindle, the spindle being configured to receive and drive a cutting tool. A clamping system is supported by the housing and a portion of the clamping system is movable relative to the spindle. The clamping system includes an actuator portion and an engaging portion coupled to the actuator portion. The clamping system has an engaged condition, in which the engaging portion is configured to secure the cutting tool to the spindle, and a released condition, in which the engaging portion is configured to disengage the cutting tool from the spindle. A biasing member positioned between the spindle and the clamping system biases the clamping system to the engaged condition. When the cutting tool is removed from the housing, the clamping system is configured to be held in the released condition, and upon insertion of the cutting tool into the housing, the clamping system moves from the released condition to the engaged condition.
