1. A milling machine comprising:
a frame;
a milling assembly coupled to the frame and including a drum housing and a cutting rotor located within the drum housing, the cutting rotor including a plurality of cutting bits configured to cut into a surface to define a cut surface having a first cut edge; and
a secondary edge cutter including a planar circular saw blade separate from the plurality of cutting bits and located behind the cutting rotor to cut the first cut edge to form a second cut edge of the cut surface, wherein the planar circular saw is configured to provide a finer cut than the plurality of cutting bits such that the second cut edge of the cut surface cut by the secondary edge cutter defines a sharper edge profile than the first cut edge of the cut surface cut by the plurality of cutting bits.
