Feature:1. Cobalt‑containing 5% cutting edge has high strength, and cobalt‑containing high‑speed steel can significantly improve the wear resistance and cutting performance of the steel2. Wide application range, high cost performance and practicality, can process stainless steel and other difficult‑to‑process metals3. Pat the debris into a spiral shape to discharge the chips upward, which is more suitable for processing into blind holes and viscous material processing4. Using highquality materials, wear resistance and durable, has a long service life5.
