The Jacobs Chuck Manufacturing Company maintains a global presence as a recognized leader in the design manufacture of precision tool and work holding devices for stationary equipment and portable power tools. From its original patent in 1902 the keyed chuck helped to transform the production process just at the time when industrial manufacturing was about to experience its most significant growth in modern times. Today, the concept of the original keyed chuck is an integral part of all drill chuck technology. It has been applied to a wide range of applications, from the most sophisticated CNC machining to drilling with the smallest cordless portable drill. Whatever the need may be we have a chuck that will work for your application.
- Split bite jaw: increases grip over standard bite chucks by providing more contact with the bit

I now have 4 of these – one on every drill I have. Locks well with normal hand strength – no need for strap wrench and ChanneLocks. Holds even on my hammer-drills.

I have two of these now and love them both. One on my hand drill and one on my drill press. Quick and easy.
