Woodworkers are discovering the benefits of retrofitting their old planers and jointers with spiral cutter heads, especially for the following reasons:
Firstly, a spiral cutter head provides a smoother finish with no tear-out. The angled position of each knife creates a shear cut, resulting in a staggered cut pattern that is superior to a single straight cut. This combined shear and staggered cut pattern eliminates tear-out and leaves a glossy finish on even highly figured hardwood.
Secondly, the noise level is significantly reduced as the spiral cutter head allows only a few knives to cut at a time in a staggered manner.
Thirdly, the inserts used in spiral cutter heads are made of sintered tungsten carbide, which is much harder than high-speed steel. With four edges on each insert, they last over ten times longer than high-speed steel.
Fourthly, the knives are easy to change and are interchangeable. With a precision ground tolerance of +/-0.0004" or +/-0.01mm, they can be rotated 90° for a new edge and tightened in just minutes.
Fifthly, the spiral cutter head produces thinner and shorter chips, making dust extraction much easier.
Finally, the cost to use a spiral cutter head is low. With a smooth finish that reduces or eliminates sanding work, and no need for sharpening, the product pays for itself in a very short time.
If you own a Grizzly G0855 8"x72" Jointer, a spiral cutter head is a worthwhile investment for achieving a superior finish on your woodworking projects.
