Helical/shelical Cutterhead for 16" jointer Delta RJ-42

Description

The list is a helical cutterhead, manufactured by WGM Tool Works, to replace the stock traditional steel cutters of a 16" Delta jointer RJ-42.
Each head features 6 rows of cutters for a total of ~100. 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

The package include:

5 additional spare carbide inserts
5 additional spare Torx screws
a wrench for installing inserts
