You can identify a carbide drill bit by its appearance and markings—carbide bits are usually heavier, harder, and often have a dull gray or silver color compared to high-speed steel bits. They may also be labeled with "carbide" or "tungsten carbide" on the shank. Additionally, the tip is often sharper and more robust, designed for drilling hard materials like metal or masonry.
