Hiboo Tools manufactures precision HRC55 corner radius end mills designed for optimal performance in semi-finishing operations on hardened steels, alloy steels, and tool steels. Our carbide end mills feature a unique corner radius design that combines the strength of square end mills with the durability of round tools, effectively distributing cutting forces and preventing corner chipping. The micro-grain carbide substrate with AlTiN coating ensures excellent wear resistance when machining materials up to 55 HRC.

Corner Radius End Mills Specifications:

Diameter range: 1mm-20mm with standard corner radius options

3/4 flute configurations for efficient material removal

Optimized helix angles for different material groups

Enhanced core strength for vibration reduction

These corner radius end mills are particularly suitable for mold base machining, die manufacturing, and component processing applications requiring enhanced tool life. The radius design provides superior edge strength compared to sharp corner tools, making them ideal for medium-to-high feed rate operations. As a leading end mill manufacturer, we ensure consistent quality through rigorous testing protocols. Contact us for specific application recommendations and custom solution development.
