In precision machining of non-ferrous metals and non-metallic materials, cutting tools must meet demanding performance standards. This is especially true when machining high-viscosity materials such as pure copper. These applications require extremely sharp cutting edges, excellent anti-adhesion properties, and consistent chip evacuation.
The SAMHO 4-flute corner radius end mill with DLC coating (D1–D12 mm) is specifically engineered for these challenges. Based on extensive CNC machining experience, this tool is optimized for stable and efficient copper cutting. The combination of a high-quality carbide substrate and a DLC coating significantly reduces friction during cutting. It also minimizes built-up edge formation, which is a common issue in copper machining.
Advanced Technical Features
In precision machining of non-ferrous metals, tool performance is critical. This is especially true when cutting highly adhesive materials such as red copper. These applications require excellent anti-adhesion properties, strong wear resistance, and consistent cutting stability.
The SAMHO DLC-coated 4-Flute bull nose end mill is engineered to meet these demands. Drawing on extensive CNC machining experience, this tool combines optimized geometry with advanced coating technology. The result is improved machining efficiency, better surface quality, and longer tool life.
