Sheartak Spiral Cutterhead for Griggio PS 520 Rapida Planer with132 Carbide Inserts

Spiral Cutterhead for Griggio PS 520 Rapida Planer with 132 carbide knives

Woodworkers are currently upgrading their aging planers and jointers by integrating spiral cutter heads, reaping numerous benefits:

Enhanced Surface Quality: With each knife positioned at a slight angle, spiral cutter heads execute a shear cut, resulting in a remarkably smooth finish devoid of tear-out. The staggered cutting pattern surpasses the efficacy of single straight cuts, particularly evident on intricately patterned hardwoods.

Reduced Noise Levels: The staggered arrangement of the knives in spiral cutter heads significantly diminishes noise during operation.

Extended Lifespan: Utilizing sintered tungsten carbide inserts measuring 15x15x2.5mm, spiral cutter heads outlast traditional high-speed steel by over tenfold. Each insert boasts four edges, ensuring prolonged functionality.

Seamless Replacement: Precision-ground knives with a tolerance of +/-0.0004" or +/-0.01mm facilitate effortless interchangeability. With a simple rotation of 90°, a fresh cutting edge is achieved within minutes, making maintenance a breeze.

Improved Dust Extraction: The spiral cutter head generates thinner and shorter chips, simplifying dust extraction processes and minimizing cleanup efforts.

Cost-Effectiveness: The superior finish produced by spiral cutter heads reduces or eliminates the need for extensive sanding, coupled with the elimination of sharpening requirements. These advantages contribute to rapid returns on investment, making the product economically advantageous over a short period.
