    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.

    Depth Stops

    Pop the 1/4" hex shank into a drill chuck, power screwdriver, or impact driver to drill and counterbore a hole in a single step. These counterbores move along the included drill bit and lock into place with set screws to match the length of the screw you're installing.
    Depth Stops—Stop your drill bit at the exact depth you need for an identical hole every time. To set the depth, slip these stops over your bit and tighten a set screw to lock them in place. A free-spinning ring on the front stops when it touches your workpiece to prevent scratches and dents. An opening in the side clears chips from the hole as you cut.
