What is the difference between high speed tool steels (HSS) materials and tungsten carbide materials?
Tungsten carbide material is better than high speed tool steels(HSS) material regarding the characteristics of Hardness, the temperature of Heat Resistance, Wear Resistance, Deflection Resistance(Young’s modulus) etc., and is applicable for harder work materials than high sped tool steels(HSS) material, is possible to mill with high velocity. However, tungsten carbide material is brittle because of its high hardness. So there are some cases that tungsten carbide material has chipping easier than high speed tool steels(HSS) material when the end mills receive shock during milling. UNION TOOL CO. manufactures all kinds of end mills with tungsten carbide materials.
