The list is a helical cutterhead, manufactured by WGM Tool Works, to replace the stock traditional steel cutterheads of a 18" Powermatic 180 (PM 180) planer. Each head features 6 rows of cutters for a total of ~108. 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 you are ready to plane again.

The advantages a helical cutterhead offers include:

• Extremely noise reduction
• No tear-out
  

• Long lasting cutter life
• No sharpening
• Easy replacement of cutters and no alignment required
