Abstract: A mill system broadly comprising a cutting system and a substrate feeder system. The cutting system broadly includes one or more bases, a mill frame, a mill housing, a motor, a power supply, a rotatable shaft, and a mill head. The mill frame supports the mill housing and may be vertically adjustable on the bases. The mill housing houses the motor, the rotatable shaft, and the mill head. The rotatable shaft transfers power from the motor to the mill head. The mill head may be a cylindrical drum or similar shape and includes a plurality of teeth formed of diamond carbide or similar material. The teeth may be positioned in a helical pattern around the mill head for evenly removing material from the substrate and may have different effective lengths for creating grooves in the substrate.
