Spiral Cutterhead for KNOVA Cepilladora para madera 20'' x 8'' bif.|KN CM-20CS1|11261

Woodworkers are now retrofitting spiral cutterheads to their old planers, and jointers for the following advantages.

* Smoother Finish with no tear-out. Each knife sits at a slight angle and produces a shear-cut. Spiral cutterhead planes board in a staggered way which is much better than a single straight cut. The combined shear and staggered cut eliminates tear-out and leaves a glossy surface finish on even highly figured hardwood.

*  Noise is dramatically reduced as the spiral cutterhead allows a few knives to cut in a staggered way.

* 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.

* Easy to change. The knives are precision ground to a tolerance of +/-0.0004" or +/-0.01mm and are interchangeable. Loosen the screw, rotate 90° for a new edge, and tighten the insert in minutes.

* Dust extraction is easier. 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, your product will pay for itself in a very short time.

Spiral Cutterhead Kit includes:

* High tensile strength alloy steel cutter block.

* 100 carbide inserts installed.

* 5 extra carbide inserts & 5 extra screws free as spare parts.
