- High-Speed Steel (HSS) 4241/4341: This material is suitable for drilling ordinary metals, such as iron, copper, aluminum alloy, and other low and medium hardness metal, as well as wood, plastic, etc. Not suitable for drilling stainless steel, mold steel, and additional high strength, high hardness metal. The quality is not bad within the scope of application, ideal for wholesale sales at hardware stores.
- HSS 4241 countersinks is ideal for use in high-temperature applications where other types of steel may deform or lose their hardness. This combination of metals makes the HSS 4241 countersinks exceptionally hard and durable, allowing them to cut through tough materials such as metal, wood, and plastic. They are commonly used in metalworking, woodworking, and other industries where precise, clean-cut holes are required. Their high durability and resistance to wear make them an excellent choice for high-volume production environments.
