Roughing end mills are designed for rapid material removal during the initial machining stages. They feature serrated or wavy cutting edges that break chips into smaller pieces, reducing cutting forces and vibration. This allows higher feed rates and deeper cuts compared to standard end mills. Roughing end mills are commonly used in steel and alloy machining for large-volume stock removal. For industrial users, these tools help shorten cycle time and improve productivity. Roughing end mills are typically followed by finishing tools to achieve final dimensions and surface finish.
