Spiral Cutterhead for Makita 1806B 6-3/4-inch Planer with 28 carbide knives

Description

Woodworkers are now retrofitting spiral cutterheads to their old planers, jointers for the following advantages.
1. Smoother Finish with no tear-out. 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 glassy surface finish on even highly figured hardwood.
2. Noise is dramatically reduced as spiral cutterhead allows a few knives to cut in a staggered way.
3. 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.
4. Easy to change. The knives are precision ground to a tolerance of +/-0.0004" or +/-0.01mm are interchangeable. Loosen the screw, rotate 90° for a new edge, tighten the insert in minutes.
5. Dust extraction is easier. Spiral cutterhead produces thinner and shorter chips.
6. Low cost to use. Spiral cutterheads produce a smoother finish, reduce or eliminate sanding work, don't require sharpening, your product will pay for itself in a very short time.
