My son in law cooped at a place that makes the signs for Lowes, and others. They cut the shapes from paper, plastic, etc. with CNC routers. Their cutters appeared to be TiN coated.
When I was researching this field I talked to a company in MN that sold tooling. They used a Vanadium nitride? coating for wood tools to lessen corrosive wear, I was told. I get a trade journal and tooling for CNC wood machining is advertised. Invariable the tool is coated with some material for some purpose that promotes longer edge life.
