ITC Carbide End Mill Square Edge 4121 - 4 Flute 30° Helix With Facet Relief & Diamond Coating - Composites - 3mm

Introducing the ITC Carbide End Mill Square Edge 4121, a high-performance cutting tool designed for composite materials. This 3 mm end mill features a 4-flute configuration with a 30° helix, facet relief, and a diamond coating to help you cut cleanly and predictably.

Built for professionals who demand precision, durability, and consistent results, this end mill delivers efficient chip evacuation and extended tool life for demanding composite applications—from prototypes to production runs.

• Diamond coating for extended tool life: The diamond coating reduces wear on tough composite materials, helping you achieve longer tool life and fewer tool changes.
• 4-flute design for smooth, precise cuts: More flutes mean efficient material removal and a cleaner finish, with stable performance across challenging composites.
• 30° helix with facet relief for consistent performance: The 30-degree helix paired with facet relief improves chip evacuation and cutting stability, reducing chatter and heat buildup.

With the ITC 4121, you can approach each job with confidence: durable coating, stable cutting, and efficient chip evacuation mean fewer slows and stops, better surface finish, and extended tool life. Ideal for engineers, machinists, and fabricators working with composites, this end mill helps you finish parts faster and with repeatable quality.
