    Quick-Change Hex Drill-Bit Countersinks for Wood and Plastic

    Switch bits instead of tools to simplify jobs. These snap directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. You can slide the countersink up and down the drill bit and then secure it with a set screw, so one tool will drill countersunk holes for screws of different lengths. These countersinks cut a smooth and even finish in wood and plastic on the first pass.

    These wear-resistant countersinks cut faster and last longer than carbon steel countersinks, so they’re often used for high-volume jobs. You can also use them on harder materials, such as steel and stainless steel.
