Hex-Shank Drill Chucks for Power Screwdrivers and Impact Drivers

Adapt your power screwdriver, impact driver, or other hex-shank drive tool into a drill. These chucks have a 1/4" hex shank that slots into your tool’s hex drive. They’re also known as adapt-a-drive chucks.
Keyless chucks let you swap bits in and out with a quick twist of the sleeve. These chucks have a ratchet lock that secures bits tightly and absorbs vibration to prevent the jaws from loosening. Chucks with carbide jaws resist wear better than chucks with steel jaws, so they maintain a tighter grip on your bit over time. However, they’re more brittle than chucks with steel jaws, so they can chip or crack if dropped.
Keyed chucks grip your bit tighter than keyless chucks. Use the included key to tighten or loosen the jaws.
Jacobs chucks are the most widely used drill chucks. Rohm chucks are the go-to choice for drill chucks across Europe. Made in Germany, they're precision engineered to operate smoothly and keep your bits aligned over their long life.

Drill Chucks for SDS-Plus Rotary Hammers



Turn your rotary hammer into a drill. These chucks mount directly into the SDS chuck to hold round- and hex-shank bits.
Keyless chucks let you swap bits in and out with a quick twist of the sleeve. Keyed chucks grip bits tighter than keyless chucks do. Use the included key to tighten or loosen the jaws.
Rotary only chucks require you to switch your tool into rotary-only mode before using them. Hammer and rotary chucks can be used in all modes, so you can fasten, hammer drill, and chisel with the same tool.
