Choose the right countersink angle, body diameter, and number of flutes for your application.
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.
High-Speed Steel

The choice if you're countersinking lots of holes, these wear-resistant countersinks cut faster and last longer than carbon steel.
