260 Hinge Boring Bit

A hinge boring bit (also known as a hinge cutter or hinge drill bit) is a specialized type of drill bit used for drilling holes that are specifically designed for attaching hinges to doors, cabinets, and other wooden structures. These bits are typically used by carpenters, cabinetmakers, and anyone working with woodworking projects where hinges are required. The “TC” in your query likely refers to the type of coating or material used for the cutting edges of the bit. “TC” stands for Tungsten Carbide, which is a very hard and durable material often used for the cutting edges of drill bits and other cutting tools. Tungsten carbide helps the bit maintain its sharpness and longevity when cutting through wood and other materials.
