In precision non-ferrous metal machining, tool performance demands high stability, strong wear resistance, and consistent cutting sharpness. These requirements become even more critical when machining red copper. Its high ductility often leads to material adhesion, built-up edge formation, and poor surface finish.
The SAMHO DLC-coated 4-flute long-neck flat end mill is engineered specifically for high-precision red copper machining. The DLC coating significantly reduces friction and helps prevent material sticking to the cutting edges. As a result, chip evacuation is smoother, cutting forces are lower, and tool life is extended.
Advanced Technical Features
High-Lubricity DLC Coating for Stable, Long-Life Machining Performance
Our proprietary DLC low-friction coating is engineered to improve cutting stability in demanding non-ferrous machining applications, especially for highly adhesive materials such as copper.
The coating delivers the following advantages:
