Thread-Mount Keyed Drill Chucks
Thread these chucks onto the spindle of portable drills and stationary machines to hold bits. They're a keyed chuck, so they hold the bit tightly, preventing it from slipping under load. Use the included key to tighten and loosen the jaws. If your machine doesn’t have a threaded spindle, mount them with a threaded drill chuck arbor.
To maximize grip and minimize wobble, choose a chuck where your drill bit diameter falls in the middle of the shank size range.
Light duty chucks are small and lightweight, so they're optimized for the low-torque drilling needed for wood and plastic. They have a two-piece sleeve that would wear out quickly from the friction created when drilling in hard materials such as steel.
Medium duty chucks work for most drilling jobs in metal, wood, and plastic. A one-piece sleeve keeps them rigid when drilling in hard materials, such as steel. For accuracy and longevity, they have hardened wear points and center-ground jaws that grip the bit evenly.
Heavy duty chucks give you the rigidity and heft needed for high-torque drilling in hardened metal. Their extra mass means they resist vibration and fluctuating cutting forces to keep your bit stable. While they share all of the same features as medium duty chucks—one-piece sleeve, center-ground jaws, and hardened wear points—they grip bits tighter and stay accurate longer under heavy loads.

Corrosion-Resistant Thread-Mount Keyless Drill Chucks
Made of stainless steel, these chucks are rust and corrosion resistant. A self-tightening design causes them to grip tighter as torque increases, which prevents tool-shank slippage and allows for precise drilling. They mount directly onto your machine’s threaded spindle.

Thread-Mount Keyless Drill Chucks
Mount directly onto the threaded spindle of a hand-held power drill. These chucks have a ball-bearing design that provides increased gripping force to keep the drill bit from slipping.
Economy Thread-Mount Keyed Drill Chucks
Designed for occasional use, these drill chucks mount onto small hand-held power drills with threaded spindles. They have a compact body with plain bearings and a two-piece sleeve that's best for the light force needed when drilling wood, plastic, and soft metals. Tighten the jaws with the included key to securely grip bits. They’re also known as Multi-Craft chucks.
To maximize grip and minimize wobble, choose a chuck where your drill bit diameter falls in the middle of the shank size range.

Thread-Mount Drill Chucks for Hammer Drills
Lock your bits in to handle the intense vibration and impact of hammer drilling. These chucks have a built-in ring that prevents your bit from slipping as you drill through tough materials such as concrete and masonry. They mount to the threaded spindle on your hammer drill.
Keyless chucks are a great choice for jobs that switch between hammer drilling and fastening with the same tool. Swap bits in and out with a quick twist of the sleeve. As torque increases, their grip will tighten. Twist the ring on the outside of these chucks to prevent the jaws from loosening.
Keyed chucks grip your bit tighter than keyless chucks do, so they’re better for high torque drilling. Use the included key to tighten or loosen the jaws. The ring inside these chucks absorbs vibration to prevent the jaws from loosening.

Ratchet-Locking Thread-Mount Keyless Drill Chucks
These chucks have a ratcheting mechanism which allows for easier tightening and releasing of drill bits and other tools. They mount directly onto the threaded spindle of a hand-held power drill. All have carbide jaws, which are harder and grip tighter than steel jaws. A ball-bearing design provides increased gripping force to keep the drill bit from slipping.
