Each knife sits at a slight angle and produces shear-cut . Spiral cutterhead planes board in a staggered way which is much better than single straight cut. The combined shear and staggered cut eliminates tear-out and leaves a glossy surface finish on even highly figured hardwood. * Noise is hugely reduced as spiral cutterhead allows a few knives to cut in a staggered way. * More than 10 times the life use of high-speed steel. The 15x15x2.5mm inserts are made of sintered tungsten carbide which is much harder than high-speed steel. Each insert has four edges. * Easy to change.
