A high-performance end mill designed to excel in mold and die machining applications. With a cutting diameter range of 1.0mm to 20.0mm and a cutting diameter tolerance of +0/-0.03mm, it offers precision and versatility for various workpiece sizes. The variable index flutes with helix angles of 29° and 31° contribute to increased tool life by reducing chatter vibrations and resonance, resulting in improved cutting stability. The gash tooth shape is specifically designed to prevent flute chipping, ensuring durability and reliability. Made from the finest raw materials, this end mill exhibits superior wear resistance and machining capabilities. The inclusion of a W coating further enhances its longevity and performance. With its ability to handle materials below 55 HRc, as well as pre-hardened steel, alloy steel, and carbon steel, the WXE504 is an excellent choice for demanding mold and die machining operations.
