Patent attributes
A cutter assembly is configured to interchange a cutter bit and has a plurality of retaining features to secure the cutter bit to ensure positive retention and alignment along a rotational axis. A cutter bit is retained within a slot of the retainer component and the retainer component is coupled to a chuck component. The retainer component may be detachably attachable to the chuck component by external threads that are configured to thread into the internal threads of the chuck component. The cutter bit may be retained in the slot by a threaded retainer that extends through one side of the retainer component, through a cutter aperture in the cutter bit, through the slot and into a threaded retainer aperture in the opposing side of the retainer component. The threaded retainer is configured to extend orthogonally to the slot to pull the first side of the retainer component to the second side and pinch or compress against the cutter bit therein.
