set of mini HSS circular saw blades, cutting disc, power tools for wood, plastic, aluminum

Features: 1. With high hardness and a high-temperature resistant nitride coating, the cutting blades are sharp. High speed, with superior wear resistance and a long service life. 2. Repeatedly forged with a pneumatic hammer to improve hardness and wear resistance. Under high speed, it exhibits superior fatigue strength, typical of high-speed steel. 3. To extend its service life, it is heated at high temperature and in a high concentration of nitrogen for four hours to perform a deep nitrogen treatment on the surface, giving it strong cutting performance. 4. Machine tools are used to repeatedly grind the blade surface coarsely and finely, achieving a high level of surface finish. 5. Primarily used for processing or cutting copper, iron, aluminum, alloys, and other medium-hard metal materials with narrow and deep grooves. Can also be used for milling non-metallic materials such as plastic and wood. Specifications: Description: These cutting blades are made from high-speed steel for durability, high hardness, and fast, precise cutting. They offer an extra-long service life and ensure a straight and accurate cut. When cutting stainless steel materials, it is advisable to use high-nitrogen high-speed steel or a coated blade cutter. With high hardness and a high-temperature resistant nitride coating on the surface, these cutting blades are quite sharp and are mainly used for processing or cutting copper, iron, aluminum, alloys, and other medium-hard, narrow- and deep-groove metallic materials. They can also be used for milling non-metallic materials such as plastic and wood. Features: With high hardness and a high-temperature resistant nitride coating, the cutting blades are sharp. High speed, with superior wear resistance and a long service life. Repeated forging with a pneumatic hammer improves its hardness and wear resistance. Under high speed, it exhibits superior resistance to fatigue breakage, typical of high-speed steel. To extend its lifespan, it is heated in a high-temperature, high-concentration nitrogen solution for four hours to perform a deep nitrogen treatment on the surface, resulting in superior cutting performance. Machine tools are used to repeatedly grind and grind the blade surface to achieve a high level of surface finish. Primarily used for processing or cutting copper, iron, aluminum, alloys, and other medium-hard, narrow- and deep-groove metals.
