Nicolai Diamant has been manufacturing and selling diamond tools for natural stone and glass since 1980. A constant contact with machines manufacturing companies is for Nicolai Diamant a hint in the research of alternatives to satisfy more and more complex and various needs. The comparison with new realities is for Nicolai Diamant a further goal both for technical, human and personal knowledge aspect. After all, this is the most important challenge that has spurred us to find new solutions, and to set up tools with grat technical features for customer in constant development.
