Swap out bits quickly on drill presses, milling machines, and lathes. These keyless chucks require only a twist of their sleeve to grip and release bits. They’re a great choice for low-torque, high-speed drilling. Their grip tightens as torque increases for a reliable hold on your bit. Mount them to your machine with a Jacobs taper arbor.

To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

Premium chucks stay accurate when drilling in hard materials, such as steel. They're 2-4 times more accurate than other keyless chucks and grip bits more tightly.

Jacobs chucks are the most widely used drill chucks.
