OSG Carbide 4 Flute End Mill Ball Nose Diamond Coated - Regular Length For Plastic & Graphite - 3mm

The OSG Carbide 4-Flute End Mill with a ball nose and regular-length design is a precision cutting tool crafted for plastic and graphite work. With a 3 mm diameter, it delivers smooth, accurate contours and finishes, making it a versatile choice for shaping enclosures, dashboards, and detailed features. The diamond coating enhances durability, helping you maintain sharpness through demanding projects.

Four flutes provide efficient material removal while preserving stability and control, even on delicate plastics and graphite. The combination of a ball-end profile and a diamond coating means you can achieve consistent radii and clean edges, reducing polishing time and rework in every pass.

• Diamond-coated carbide for extended life: exceptional wear resistance that keeps cutting edges sharper longer, reducing tool changes and downtime in plastic and graphite applications.
• Ball nose for precise curves and finishes: enables smooth, accurate radii and high-quality surface finishes on contoured features and complex pockets.
• Four-flute design with optimized chip evacuation: steady cutting performance, efficient material removal, and cleaner profiles across a range of feeds and speeds.

This end mill helps you maintain tight tolerances, accelerate workflows, and achieve repeatable, professional results. Its durable diamond coating and rigid regular-length body support reliable performance across everyday production and intricate prototypes, making it a dependable choice for both shop floor use and detailed fabrication work in plastics and graphite.
