Thread-Mount Keyless Drill Chucks


Switch between drilling and driving bits in seconds. These keyless chucks require only a quick twist of their sleeve to lock and release bits. Most often used in hand-held power drills, they're a great choice for most drilling and fastening jobs, including low-torque, high-speed drilling in soft or thin materials.
Economy chucks are best for occasional drilling. They are a cost-effective upgrade from the one that comes on your hand-held power drill.
Standard chucks work for most everyday drilling jobs in hand-held power drills. Their grip tightens as torque increases for a reliable hold on your bit that reduces wear to extend life. 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, so they can chip or crack if dropped.
Chucks with a ratchet lock have teeth that tightly grip bits for drilling in both directions, even under high torque and vibration. The ratcheting mechanism makes it easy to tighten and release bits. Chucks without a ratchet lock are commonly used on stationary machines, such as drill presses. Mount them with a threaded drill chuck arbor.
