The list is a helical cutterhead, manufactured by WGM Tool Works, to replace the stock traditional steel cutters of a Delta DJ-30 jointer. Each head features 4 rows of cutters for a total of ~50. Each cutter, or carbide insert in size of 15mmX15mmX2.5mm with R=6" curved edges, is made of solid carbide and will out last your steel knives by a good margin. Each insert also has four cutting sides so just rotate the one side that gets dull and your are ready to plane again.

This cutterhead also fits the following machine models:
  • DELTA 37-360
  • DELTA 37-361
