ITC Carbide End Mill Ball Nose 4072 - 4 Flute 30° Helix With Facet Relief & Diamond Coating - Composites - 4mm

The ITC Carbide End Mill Ball Nose 4072 is a high-precision carbide cutter designed for composite materials. With a 4-flute design and a 4 mm ball nose, it delivers smooth, accurate contours on complex surfaces and is well suited for aerospace, automotive, and industrial composite applications.

The 30° helix, facet relief, and diamond coating optimize cutting performance, improve chip evacuation, and extend tool life, making it a reliable choice for demanding production and hobby projects.

• Ball nose geometry for smooth, accurate contours: Reproduces complex 3D shapes with clean, uniform finishes and minimal scallop on curved surfaces.
• Diamond coating with facet relief: Exceptional wear resistance and reduced edge rubbing, helping maintain sharpness and extend tool life in tough composites.
• 30° helix with 4 flutes for stable, efficient cutting: Enhances chip evacuation and cutting stability, reducing heat buildup and delivering consistent finishes on layered materials.

Using this end mill, you gain reliable performance across demanding composite jobs. The tool's robust carbide core, diamond-coated edge, and optimized geometry help reduce rework, improve surface quality, and shorten cycle times. Its durability and predictable results support smoother workflows, fewer tool changes, and higher overall part quality across production runs and precision projects.
