Titanium Burr Grinders
To get any more production out of a set of burrs, you have to start coating the steel with other super-substances. The most common one is Titanium Nitride (TiN). It is identifiable because of the gold coloration the TiN coating puts on the burr. In order to apply the coating, the steel must be super-heated which can cause most steel burrs to warp. Because of this, it is necessary to use Tool Steel as the base for TiN burrs. This results in very hard steel with a very low friction coefficient. This means that you first wear out the TiN and then you wear out the Tool Steel creating a 64mm burr that will grind 3,000-3,100lbs before it needs to be changed.
