4 Flutes Corner Radius End Mill

DLC Coating Offers Exceptional Anti-Adhesion and Surface Finish for Soft Metals

The DLC coating provides ultra-low friction and strong anti-stick properties, effectively preventing built-up edge when machining red copper, aluminum alloys, and resin-based materials. This ensures mirror-like surface finishes, tool wear reduction, and improved chip evacuation—especially in dry or semi-dry machining environments.

4-Flute Design Enhances Cutting Stability and Productivity

Compared to 2-flute tools, the 4-flute structure distributes cutting forces more evenly, allowing for higher feed rates and smoother surface finishes. Ideal for finishing operations in non-ferrous materials, the design supports both high-speed and high-efficiency milling without compromising tool rigidity.

Corner Radius Geometry Boosts Tool Strength and Reduces Chipping

The corner radius edge blends strength and precision—offering improved resistance to edge chipping while maintaining fine corner detail in part profiles. Especially useful in finishing electrode molds, connector housings, and aluminum alloy molds requiring both durability and high dimensional accuracy.

Optimized for Semi-Finishing and Finishing in Soft, Ductile Materials

Whether machining high-purity copper, 6xxx/7xxx series aluminum, or engineering plastics, this tool delivers stable performance and exceptional edge retention. The combination of DLC coating, corner radius geometry, and multi-flute design makes it suitable for light-to-moderate cutting depths with consistent surface integrity.

Mirror-Polished Flutes Promote Chip Flow and Thermal Control

Highly polished flute surfaces reduce friction and thermal buildup while improving chip removal—especially important when machining sticky materials like copper. This ensures dimensional stability, clean part edges, and longer tool life.

Application-Specific Cutting Parameters Provided for Easy Integration

Each tool includes recommended parameters (cutting speed, feed rate, depth of cut) for copper, aluminum, and resin materials. This minimizes trial-and-error during setup and helps users optimize performance from the first use, improving efficiency and cost control.
