Indexable Design: Carbide inserts have 4 sharp cutting edges. When one side of the blade becomes dull, the indexable design allows you to rotate it to get a new sharp edge
Smooth Results: The spiral cutter head increases the efficiency of woodworking jointers, cutting smoothly, creating high precision and smoother results on the wood
Durability: High hardness carbide inserts provide longer service times than HSS straight blades. The spiral cutterhead has a black coating to prevent rust and corrosion, which improves durability
