Carbide burrs, also known as rotary burrs, are used for cutting, shaping, grinding, and the removal of sharp edges, burrs, and excess material (deburring). They are widely used in various industries such as metalwork, tool making, engineering, model engineering, wood carving, jewelry making, welding, and chamfering. Carbide burrs can be used on a variety of materials including metals (steel, aluminum, cast iron, etc.), wood, acrylics, fiberglass, plastics, and ceramics. They come in different cuts, such as single cut and double cut, with each cut being suitable for specific materials and applications. Single cut burrs are used for heavy stock removal, milling, deburring, and cleaning, while double cut burrs are used for faster material removal and a smoother finish. They are typically used with air tools such as die grinders, pneumatic rotary tools, high-speed engravers, and other rotary tools. Carbide burrs are not typically used with cutting oil or compound, as their design is intended for fast metal removal without the need for lubrication. They are also recommended for use at high speeds, but can also be used at lower speeds such as in an electric drill.
