ITC Carbide End Mill Square Edge 4121 - 4 Flute 30° Helix With Facet Relief & Diamond Coating - Composites - 2mm

The ITC Carbide End Mill Square Edge 4121 is a high-performance carbide tool engineered for composite materials. It features a 4-flute design, a 30° helix, facet relief, and a diamond coating to deliver precision, stability, and exceptional wear resistance.

This square-edge end mill is designed for professionals who require clean edges, reliable cutting, and extended tool life when machining complex composites.

• Diamond Coating for Extended Tool Life: The diamond coating minimizes wear when cutting abrasive composite materials, translating to longer tool life, fewer tool changes, and more consistent finishes.
• 4-Flute Design with 30° Helix for Efficient Cutting: The four-flute geometry combined with a 30° helix provides strong cutting stability, faster material removal, and reliable chip evacuation for smoother operation in composites.
• Facet Relief and Square Edge for Clean, Precise Edges: Facet relief reduces rubbing and heat buildup, while the square-edge geometry helps produce crisp, repeatable edges and improved surface quality.

Designed for professionals across engineering, fabrication, and skilled hobbyist projects, this end mill delivers repeatable, high-quality results in composites. The combination of a wear-resistant coating, robust flute design, and precise edge geometry reduces downtime, minimizes rework, and supports dependable performance in demanding applications.
