60 Degree Tungsten Carbide Countersink Drill Bit 12mm*13mm On 6mm Shank
The SJ 60° countersink tungsten carbide burr is a rotary tool specifically designed for chamfering, deburring, and creating countersinks in various materials, such as metals, plastics, and wood. It features a conical shape with a 60° angle, making it ideal for forming angled edges or preparing holes for flathead screws.
The SJ-3 burr is often used in metalworking, woodworking, and automotive industries for precision tasks involving angled cuts or hole preparation. It works best with die grinders and rotary tools for high-speed applications.
