Carbide rotary burrs, also known as rotary burrs, are cutting tools made of high-speed steel or tungsten carbide and are used in metalworking, woodworking, and other industrial applications. They feature a rotating cutting head that spins at high speeds, usually in the range of thousands of RPM, and cuts or shapes the material as it rotates.

The main uses of rotary burrs include:

• Deburring: Removing sharp edges or burrs from metal, plastic, or other materials.
• Shaping: Creating complex shapes and contours in metal, plastic, or other materials.
• Surface finishing: Removing surface imperfections and creating smooth finishes on metal, plastic, or other materials.
• Welding preparation: Removing excess material and preparing surfaces for welding.
• Wood carving: Creating intricate shapes and designs in wood.
• Rust and paint removal: Removing rust, paint, or other coatings from metal surfaces.
• Dental and jewelry making: Creating intricate shapes and designs in dental work and jewelry.

The type of rotary burr used in a given application will depend on the material you are working with, the required cutting or shaping performance, and the desired finish. Different shapes of rotary burrs are designed for specific applications, such as cylindrical burrs for material removal in tight spaces, spherical burrs for creating smooth finishes, and conical burrs for reaching narrow areas.

In conclusion, carbide rotary burrs are versatile cutting tools with a wide range of uses in metalworking, woodworking, and other industrial applications. They are an important tool for achieving precise cuts and shapes and are widely used in a variety of industries and applications.
