Drill, enlarge, and finish a wide range of hole sizes in seconds with just three bits. Made with an oversized shank and hardened high-speed steel, the bits in these sets are built to handle the high torque of your impact wrench without snapping. A built-in pilot has a stepped tip that bites material immediately, centers the tool, and prevents slipping. The steps on the bit have progressively larger diameters—the deeper you drill, the bigger the hole. Count the steps as you drill to achieve the proper size. Like a reamer, these bits leave a smooth, precise hole at each step. If you’re drilling to the bit’s maximum diameter, a safety collar stops the bit at that size. Since these bits deburr as they cut, they’re often used for thin workpieces, such as sheet metal and plastic panels.

You’ll need a VersaDrive chuck (sold separately) to install these bits into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these bits directly into a _1/2" chuck on a standard power drill.
