Helical/shelical Cutterhead for 10" jointer Oliver 4240

Description

The list is a helical cutterhead, manufactured by WGM Tool Works, to replace the stock traditional steel cutters of a 10" Oliver jointer 4240.
Each head features 4 rows of cutters for a total of ~41. Each cutter, or carbide insert in a size of 15mmX15mmX2.5mm, is solid carbide and will outlast 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 go again.
The advantages a helical cutterhead offers include:
Chip outs largely eliminated
Extremely noise reduction
Long lasting cutter life
No sharpening
Easy replacement of cutters and no alignment required
