Convert a power screwdriver or impact driver into a versatile drill. Also known as adapt-a-drive, these chucks have a 1/4" hex shank that fits the hex drive in most power screwdrivers and impact drivers.

Choose a DeWalt, Makita, or Milwaukee brand chuck or a Jacobs brand equivalent that matches your cordless drill model number.

Use the included spanner wrench to tighten the chuck for up to three times the gripping torque of hand tightening.
