Woodworkers are now experiencing the benefits of retrofitting spiral cutterheads to their old planers and jointers, including:

• A smoother finish with no tear-out. Each knife sits at a slight angle, producing a shear-cut that planes boards in a staggered way, resulting in a much better surface finish than a single straight cut. The combined shear and staggered cut eliminates tear-out and leaves a glossy surface finish even on highly figured hardwoods.
• Dramatically reduced noise as the spiral cutterhead allows a few knives to cut in a staggered way.
• A longer lifespan, with over 10 times the use of high-speed steel. The 15x15x2.5mm inserts are made of sintered tungsten carbide, which is much harder than high-speed steel, and each insert has four edges.
• Ease of use, with precision ground knives interchangeable to a tolerance of +/-0.0004" or +/-0.01mm. Simply loosen the screw, rotate 90° for a new edge, and tighten the insert in minutes.
• Easier dust extraction, as the spiral cutterhead produces thinner and shorter chips.
• Low cost to use. Spiral cutterheads produce a smoother finish, reduce or eliminate sanding work, and don't require sharpening, so your product will pay for itself in a very short time.
