RUBY

The specialization of the Ruby Boride series is the roughing stage of metal processing. In the Ruby grit line, there are only peeling stones from 60 to 220 grit. The abrasive grain of the Ruby series bars is electrocorundum alloyed with zirconium, the bond is quite soft. This gives the stones of this series an extremely high abrasive capacity, which guarantees a high material removal rate on any steel. The Golden Star series is non-impregnated, has an open structure, requires soaking before use and is generally recommended for use with water or water soluble cutting oils.
