5/8" Diam 4-Flute 30&deg MPN:66314-00-W

The 5/8-inch diameter, four-flute end mill is crafted from high-speed steel (HSS) for durability and cutting efficiency, designed with a 30-degree helix angle for optimized chip removal in stainless steel, aluminum, brass, and other mild metals. Its coated finish provides better lubrication during operation to minimize friction, while its sharp teeth are laser cut for precision and longevity, making it an ideal tool for industries such as aerospace engineering, automotive manufacturing, die & mold construction, or general machining applications. The end mill's 0.8% cobalt composition increases resistance to heat buildup at higher speeds and reduces burr formation upon contact, further enhancing its performance across diverse projects.
