Spiral cutterheads are quieter, require less energy to operate, reduce or eliminate sanding work, don’t require sharpening and leave a smoother finish, with no tear-out, especially when it comes to figured woods. Each knife is staggered on the cutterhead and sits at a slight angle to produce a shearing cut. This combined shear and staggered cut delivers the best finish you can get on a thickness planer or jointer.
Installing inserts is very easy. You simply loosen a screw, rotate the insert 90° for a new edge, and then re-tighten the insert.
