These cutting discs are equipped with a patented helicoidal system, which causes less heat dissipation in the material. The very low thickness allows to halve the cutting rate compared to standard wheels. A press with advanced technology generates a spiral pattern on both sides of the disk which results in an alternation of low-and pressure-relief surfaces. This patented technology ensures reduced heat generation in the material, low cutting friction, improved cutting speed, more rigidity, high cutting capacity coupled to an extreme durability.
