Solid Carbide End Mills, Diameter: 30 mm

Carbide is a hard material that is often used in drill bits because it can drill through almost any material and can hold an edge longer than other materials. However, it is brittle and expensive, so it is usually used as a tip for a drill bit made of a less hard metal. Solid carbide bits are becoming more common, especially in industries that require many small holes, such as printed circuit board manufacturing.
