1. Classification according to the driving device used:
1. Pneumatic socket (also known as pneumatic socket) 2. Manual socket 3. Electric socket: a socket with an electric wrench as the driving force.
Second, according to the material classification
1. Chrome-Molybdenum Steel is an alloy of chromium (Cr), molybdenum (Mo), iron (Fe), and carbon (C). It has good high-temperature processing performance, beautiful after processing, and can be deeply quenched. It has good absorption performance, so it is often used in the industry to manufacture pneumatic tools and large hand tools.
2. Chrome-Vanadium Steel, Chrome-Vanadium Steel is an alloy tool steel with chromium-vanadium alloying elements, mainly used in hand tools.
3. 45# carbon steel, namely No. 45 steel, has a carbon content of about 0.45%. Due to its good processing performance and multi-directional processing technology, it has become a commonly used processing material in steel. Among the above materials, Cr-Mo (chromium molybdenum steel) material is the material of the sleeve.
