    These countersinks attach at various points along the drill bit, so one tool will drill countersunk holes for screws of different lengths. They're designed to cut a smooth and even finish in wood and plastic on the first pass.
    High-Speed Steel—The choice if you're countersinking lots of holes, these wear-resistant countersinks cut faster and last longer than carbon steel.
    Carbon Steel—Stronger than high-speed steel, so it will cut through harder materials. However, high-speed steel is more precise, lasts longer, and cuts at higher speeds.
