Steel City 4-Sided Carbide Cutters for Helical Cutterheads, pack of 10

The helical cutterhead for Steel City's 8" jointer uses 16 of these individual carbide cutters. The 6" helical jointer uses 12. Each cutter has 4 sharpened edges, and can be rotated to expose a fresh sharp edge until all 4 have become dull. If one cutter becomes nicked as a result of striking embedded metal, just that cutter needs to be replaced to eliminate the ridge that the nick causes on the workpiece.
