Suitable for general-purpose machining on hardened and high-alloy steel, steel casting, malleable cast iron, chromium-nickel steel, brass, copper, aluminum with a high percentage of silicon, and abrasive plastic
Extra-long-length end mills have longer cutting edges and can make deeper cuts than long-length end mills
Four flutes produce a better finish than fewer flutes
Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures
Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
