Woodworkers are upgrading their old planers and jointers by retrofitting them with spiral cutterheads, which offer several advantages:

1.    Improved Surface Finish: The spiral cutterhead features knives that are angled to produce a shear-cut, resulting in a smoother finish with no tear-out. The staggered cutting pattern is superior to a single straight cut and eliminates any roughness, even on highly figured hardwood.

2.    Reduced Noise: The spiral cutterhead cuts with a staggered motion, reducing noise levels.

3.    Increased Lifespan: The spiral cutterhead is made with sintered tungsten carbide inserts that have four edges, providing more than 10 times the life use of high-speed steel.

4.    Easy to Change: The knives are interchangeable and precision ground to a tolerance of +/-0.0004" or +/-0.01mm. Changing knives is a breeze: loosen the screw, rotate 90° for a new edge, and tighten the insert in minutes, reducing production time by 30%.

5.    Improved Dust Extraction: The spiral cutterhead produces thinner and shorter chips, making dust extraction easier.

6.    Low Cost to Use: The spiral cutterhead produces a smoother finish, reducing or eliminating the need for sanding. With no sharpening required, the product pays for itself in a short time.
