A milling cutter includes a milling drum having a body with a first end, a second end, an outer surface extending around a circumference of the body between the first and second ends, and a plurality of slots formed in the outer surface. The plurality of slots arranged in a staggered row between the first end and the second end of the body. The milling cutter also includes a plurality of cutting insert removably secured to the body. Each cutting insert is positioned at least partially within one of the plurality of slots and includes a cutting profile defined by rounded peaks and pointed valleys to cut a tooth form into a saw blade. The plurality of cutting inserts are staggered such that the plurality of cutting inserts are circumferentially offset from each other along a longitudinal axis of the milling drum.
