Higher hardness and wear resistance



The hardness of the cutting part of the tool must be higher than the hardness of the workpiece material, and the higher the hardness of the tool material, the better its resistance. The hardness of the cutting tool material at room temperature should be above HRC62



Sufficient strength and toughness



Cutting tools are subjected to significant pressure during excessive cutting, and sometimes work under impact and vibration conditions. In order to prevent tool breakage and fracture, the tool material must have sufficient strength and toughness. Generally, the strength of the tool material is represented by its flexural strength, and its toughness is represented by its impact value,



higher heat resistance 



Heat resistance refers to the performance of tool materials in maintaining hardness, resistance, strength, and toughness at high temperatures. It is the main indicator for measuring the cutting performance of tool materials, also known as the red hardness of tool materials.



Good thermal conductivity



The higher the thermal conductivity of the tool material, the more heat the tool emits, which is beneficial for reducing the cutting temperature of the tool and improving its durability,



Good processability
