High hardness and wear resistance
The hardness of the cutting part of the tool must be higher than the hardness of the workpiece material. The higher the hardness of the tool material, the better its durability. The hardness of the tool material at room temperature should be above HRC62
Sufficient strength and toughness
The cutting tool bears a great deal of pressure during excessive cutting, sometimes working under impact and vibration conditions. In order to prevent the tool from collapsing and breaking, the tool material must have sufficient strength and toughness. Generally, the bending strength is used to represent the strength of the tool material, and the impact value is used to represent the toughness of the tool material,
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, and this performance is also known as the red hardness of tool materials.
Good thermal conductivity
The larger the thermal conductivity of the tool material, the more heat is transferred from the tool, which is beneficial for reducing the cutting temperature of the tool and improving its durability,
Good craftsmanship
