Spiral Cutterhead for Hitachi F1000A Planer Jointer with 40 Carbide Inserts
Woodworkers are now retrofitting spiral cutter heads to their old planers, jointers for the following advantages.
* Smoother Finish with no tear-out. Each knife sits at a slight angle and it produces a shear-cut. Spiral cutter head planes board in a staggered cut which is much better than a single straight cut. The combined shear and staggered cut eliminates tear-out and leaves a glossy surface finish on even highly figured hardwood.
