Helical/Shelical Cutterhead 8" Delta DJ-20 Jointer, Grizzly G0490, ShopFox W1741

Description

The Delta DJ-20 is one of the most desirable vintage 8" jointers out there. This is a helical cutter head, manufactured by WGM Tool Works, to replace the stock traditional steel cutters. Each head features 4 rows of cutters for a total of ~32(already installed on the cutterhead).  Each cutter, or carbide insert, is solid carbide and will out last your steel knives by a good margin. Each insert (15mm X 15mm X 2.5mm) also has four cutting sides so just rotate the one side that gets dull and your are ready to join again.
