(2) Medium carbon steel base (handle), unique edge head connection technology, high-frequency automatic fiber welding technology.The tensile strength is greater than 200mpa, the connection between the blade head and the handle is more stable, the concentricity is higher, it will not shake or turn around during use, it is more stable, safe, and has higher wear resistance. (3) It can freely machine various metals (including hardened steel) and non-metallic materials (such as marble, jade, and bone) with HRC70 or less. (4) It can replace small grinding wheels with handles in the vast majority of work and causes no dust pollution. It has a high production efficiency, which is dozens of times higher than that processed by manual files and nearly ten times higher than that processed by small grinding wheels with handles. The processing quality is good, the surface finish is high, and it can process various high-precision mold cavities of different shapes. (5) It has a long service life, being ten times more durable than high-speed steel tools and more durable than alumina grinding wheels
