Diamond Inside is a patented process for thermal cryogenic treatment of burrs at temperature -193° C resulting in the formation of a increased crystal structure that guarantees a superior wear resistance and duration.

Diamond Inside is able to preserve the optimal geometry of the sharpening longer than any other burrs typology. It allows to keep the granulometry constant for an exceptionally high quantity of ground coffee: around 1300 kg with burrs of 65 mm, while the total duration can reach up to 1500/1600 kg.
