4-Row Design with 28 Carbide Inserts
This helical cutterhead we designed for the Jet 6" Jointer features 28 carbide inserts arranged in a 4-row design for unmatched durability and performance. These inserts last up to 40x longer than traditional high-speed steel blades, saving you money and reducing downtime. This innovative design also produces smaller wood chips, making cleanup easier and increasing dust collection efficiency.

Super Smooth Surface Finish
Reduces snipe and tear-out. Our Jet 6" Jointer spiral helical cutterhead delivers a professional-grade finish every time. Unlike traditional straight cutterhead that cut through wood, the angled helical cutterhead cuts cleanly through wood fibers, eliminating tearing, shearing, and splintering. Even when dealing with tricky wood grains like curly maple or knotty pine, you get a smoother surface with minimal sanding. The continuous cutting motion also reduces vibration and ensures consistent results, there will be a smoother surface.
