Special sound-absorbing material is placed in specific laser grooves placed in special positions and different for each diameter of circular saw blade. Size of laser cuts not too big, and special shape were studied for circular saw blades for panel, where the
strength of the body subjected to great efforts must not be compromised.
With this solution the noise and vibration are absorbed and obtained cutting quality and the duration of the circular saw blade BLACK SILENT GDA for panel are unique.
Similar concept but different geometry for aluminium circular saw blades, again a special cut was designed to bring out the best performance of this type of blade. The BLACK SILENT special resin is resistant to ultrasonic and high temperatures, so even after several regrinding the treatment efficiency is guaranteed.
