GC - Corner Radius End Mills - For Mold Steel - 4-Flutes - 35° Helix

Product Overview

The GC Series Corner Radius End Mill is a high-performance, high-rigidity, and high-precision cutting tool specifically designed for machining high-hardness materials such as die steel and hardened steel. Made from solid carbide, the tool offers excellent wear resistance and thermal stability, ensuring long-lasting performance under high-speed and heavy-load conditions. The cutting edge is enhanced with advanced composite coating technology to further improve wear resistance and cutting efficiency.

Corner-radius end mills have a square nose with slightly rounded corners that help distribute cutting forces evenly to prevent damage to the end mill and extend its life. Sometimes called bull-nose end mills, they are rotated against a workpiece to create a flat-bottomed groove with slightly rounded inside corners in milling applications that require a specific radius. 

The tool supports various machining methods such as slot milling, side milling, and face milling, and it is particularly suited for contouring operations. It is suitable for processing materials such as steel parts, cast iron, quenched steel, and hardened steel, and is widely used in precision machining industries such as mold manufacturing, aerospace, automotive parts, and machinery manufacturing.
