The TIN coating provides improved heat and wear resistance and makes it easy to detect wear.



Cubic Boron Nitride (CBN) is the second hardest material ever invented and has considerably better abrasive resistance than tungsten carbide and ceramics. With a higher ability of oxidation resistance at high temperatures. CBN does not have any chemical reactions with ferrous material in the 1200°C to 1300°C range and thus is unique for dry cutting of ferrous materials.
