How to recognize and use the carbide tools and HSS tools?1. The difference in weight is the most simple and direct, due to the high density of carbide cutting tools, the carbide cutting tools is more heavy than HSS cutting tools if same size.
2. Different color of material , the appearance of carbide cutting tools is bright but little black. The appearance of HSS tool is bright and more white.
3. Different coating, carbide cutting tools are generally coated with bronze, black, blue, high-speed steel cutting tools are generally plain or yellow.
4. Price difference, carbide cutting tool price is more high, high-speed steel cutting tool price is low if same size.
5. Difference in use, carbide tools cutting speed, long performance life, high-speed steel tools are easy to wear, low service life. Cemented carbide tool hardness is high but easy to break, the edge is easy to collapse if drop on the ground, high-speed steel tool toughness is not easy to collapse edge
6. Cemented carbide tools are generally processed ferrous metal materials, and the use of high-speed steel tools to process non-ferrous metal materials. Cemented carbide hardness, especially at high temperatures, can withstand higher cutting speeds, but the toughness of HSS tools is better,generally used in some complex and difficult to mold or require sharpness and high toughness and other occasions.
7. Whether choose tools for CNC machine tool or general machine tool, we have to comprehensively consider the milling material and hardness, milling specifications, such as: cutting edge length, cutter length, cutting edge diameter, shank diameter and so on. HSS tools are usually suitable for general machine tools, while CNC machine tools better use carbide tools.
