What is a tungsten steel concave convex semi-circular milling cutter

Sources：www.qdweb.com.cn | PublishDate：2025.11.04

      Tungsten steel concave convex semi-circular milling cutter is a cutting tool made of tungsten steel (hard alloy) with a concave convex semi-circular blade shape. Its core is used to machine workpieces with circular arc surfaces, curved surfaces, or grooves.
Core Features and Applications
      Material advantages: Tungsten steel has high hardness, strong wear resistance, excellent high temperature resistance, and a service life exceeding that of high-speed steel milling cutters. It is suitable for processing high-strength materials.
      Structural features: Convex semi-circular milling cutters are used for machining concave circular arc surfaces, while concave semi-circular milling cutters are used for machining convex circular arc surfaces. They can be combined to complete complex surface machining.
      Applicable scenarios: Widely used in industries such as mold manufacturing, mechanical processing, automotive parts, precision instruments, etc., for processing structures such as cavities, circular grooves, and curved surfaces.
