A cutter assembly includes a disc subassembly rotatably mounted on a shaft with bearing assemblies, and end retainers. The disc subassembly includes a first hub member having a tubular portion that houses the bearing assemblies and an outer flange portion, a second hub member that slidably engages the tubular portion, and an annular cutter ring, preferably formed from a tool steel, and optionally formed in a plurality of segments. The first and second hub members define a channel that receives and clampingly engages a rectangular inner base portion of the cutter ring. The clamping force is provided by a plurality of bolts that join the first and second hub members, while the flange portion of the first hub member remains separated from the second hub member by a gap (S). In an embodiment the cutter ring includes a carbide core.
