The AMANA 59000 Carbide 6-Pc boxed set is a router bit set that includes a Rosette cutter with interchangeable knives. The set is made of carbide-tipped tool steel and is designed for cabinet construction and woodworking applications. The set is new old stock (NOS). 
  This set is about 20 years old and has been in storage yet all cutters, knives and bushings appear new and un-used and in excellent condition as does the factory wood box. The included two two-set different-shaped knives still have on the factory protective rubber(?) coating on the blades. Many more various knife shapes are available to fit this cutter - see the factory catalog for their offerings.
  I have many more different high-quality boxed sets from various makers plus many individual bits, all obtained from a storage unit sale. If interested please see my other auctions as I get them posted and ask questions. Thanks!
