ITC Carbide End Mill Square Edge 4121 - 4 Flute 30° Helix With Facet Relief & Diamond Coating - Composites - 8mm

Introducing the ITC Carbide End Mill Square Edge 4121, an 8 mm diameter cutting tool engineered for reliable, precision cutting in composite materials. Designed for professionals who demand accuracy, durability, and high-quality finishes, it features a 4-flute design with a 30° helix. Facet relief and a diamond coating further improve chip control and extend tool life.

• Diamond coating for extended tool life: The diamond coating provides exceptional hardness and heat resistance, delivering longer tool life in abrasive composites and reducing tool changes on demanding jobs.
• 4-flute design with 30° helix and facet relief: This combination promotes stable cutting, efficient chip evacuation, and smooth surface finishes on composite materials, even in challenging pockets and slots.
• Square-edge geometry for clean, accurate finishes: Precise, burr-free edges and consistent surface quality help meet tight tolerances on CFRP, fiberglass, and other composites, with reliable repeatability across runs.

With this end mill, you’ll experience reliable performance, faster setup times, and cleaner results when machining composites. The durable diamond coating and optimized geometry work together to minimize downtime, reduce rework, and deliver consistent, high-quality finishes project after project.
