Dayton keyless drill chucks are suitable for drilling small to medium type holes, as they quickly loosen or tighten a tool on the chuck collar, either by manual operation or when torque is applied. These chucks have HSS (high speed steel) construction, providing hardness and abrasion resistance and feature internal threads for a secure connection. They are further integrated with plain bearings for lower friction losses to deliver high accuracy and gripping power. Choose from a wide range of these drill chucks, available in 1/2 and 1/4 inch maximum drill capacities.
