Carbide burrs, also known as carbide rotary files, are cutting tools used for shaping, deburring, and removing material in various applications. They are commonly used in metalworking, woodworking, and other industries where precision and efficiency are required. 

Carbide burrs are made from tungsten carbide, a hard and durable material that retains sharpness even when subjected to high heat and pressure. The burrs have a cylindrical or conical shape with multiple cutting flutes or teeth on their surface. These cutting edges allow for rapid stock removal and precise shaping of materials such as metal, wood, plastics, and composites. 

Carbide burrs are typically used with handheld rotary tools, die grinders, or CNC machines. They offer versatility in terms of material compatibility and can be used for tasks like shaping, deburring, chamfering, grinding, and carving. Different burr shapes and sizes are available to suit specific applications, allowing craftsmen and machinists to achieve intricate and accurate results in their work.
