1. Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
2. Round shanks allow use with a wide variety of toolholding systems
3. 3 flute design will usually allow feed rates 50 percent faster than 2 flute tools
4. Used for general purpose milling in most materials of medium hardness such as steel, brass, iron, and nonferrous materials
