The Zefam 12" Jointer can be upgraded with with a Spiral Cutter Head that features 104 carbide inserts. Woodworkers are retrofitting their old planers and jointers with this technology due to the following benefits:
- Improved Finish: The spiral cutter head's slight angle and staggered cut produce a shear cut that results in a smooth finish with no tear-out. This is particularly effective on highly figured hardwood.
- Reduced Noise: The staggered cutting pattern of the spiral cutter head reduces noise compared to traditional straight cutters.
- Increased Durability: The sintered tungsten carbide inserts are much harder than high-speed steel and have four edges each. They can last over 10 times longer than high-speed steel blades.
- Easy Maintenance: The interchangeable knives are ground with a tolerance of +/-0.0004" or +/-0.01mm and can be changed in minutes. Simply loosen the screw, rotate 90° for a new edge, and tighten the insert.
- Better Dust Extraction: The spiral cutter head produces thinner and shorter chips that are easier to extract.
- Cost-Effective: The spiral cutter head's smooth finish reduces the need for sanding and doesn't require sharpening, making it a cost-effective choice that can pay for itself quickly.
