Cobalt obstructs critical grain growth and above all, maintains an excellent degree of hardness at high operating temperatures. These characteristics are very important when cutting very high-alloy materials such as stainless steel and very hard metals, which tend to develop high temperatures in the cutting zone. Hardness of this steel: 65 ± 1HRC. Kx coating: Provides much longer tool life than steam treated blades (see Art. 5 1300). Furthermore: – High resistance in high work temperatures. Therefore ideal also in cuts with insufficient cooling, minimal cooling, spray oil (mist). – Due to low friction coefficient (0.50) and high surface hardness of 3500 HV suitable for higher cutting speed. Therefore ideal for automatic machines.
