- Carbide bur bits are the universal tool for handheld die grinder applications. Used for deburring and grinding, these tools are available in single, double or non-ferrous cut. The single cut carbide bur has less tendency to load up, but pulls in one direction, making the double-cut carbide bur the much more popular choice, due to the ease of operator use with the diamond pattern. Choose the non-ferrous cut burs for aluminum and other materials that require greater chip evacuation. These tools are also used with equipment such as robotic arms to perform automated deuburring and ginding tasks. We stock a large selection of long carbide burs and a unique selection of bur sets, to meet the demand for your bur requirements.
