Cylinder Radius Burrs
Product Description
Tungsten carbide burrs, also known as rotary burrs and grinding burrs, are a small cutting tool used to cut, grind or smooth metal. They are used extensively in workshops throughout the world. The carbide burr is characterised by a cylindrical shank with a cutting head. There are numerous head shapes and sizes designed for different applications. The head has many small cutting teeth which gives the burr a smooth finishing action. The teeth pattern is called the cut or fluting pattern. Different cuts are suited to different materials or applications.
