Made of stainless steel, these chucks maintain smooth, precise operation even when exposed to moisture and chemicals. They’re keyed, so their jaw locks securely around bits.

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

Also known as positive-drive drill chucks, these chucks mount to the pin-drive tapered spindles on mud mixers and older drills.

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

Made of stainless steel, these chucks are rust and corrosion resistant.
