A set of 64mm flat steel burrs that have been titanium coated. To improve the longevity of the burrs, ECM powder coats them with titanium nitride which is an extremely hard ceramic and fires them. The advantage to doing so is that the cutting edges of the burrs are kept sharper for much longer, increasing the grinding lifespan from the typical 350/400 kg of coffee to a much greater 1,200kg of coffee. The titanium coating also adds a golden hue to the burrs for a more attractive appearance. Compatible with the Following ECM Grinders: ECM S-Manuale 64, ECM S-Automatik 64, and ECM V-Titan 64.
