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.

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.

Finding a better way through world-class innovation and world-class partnerships - that's the driving force behind our business. It's a tradition that began with A.I. Jacobs a century ago when he set up his first network of distributors for the toothed sleeve and keyed drill chuck. It's a tradition we will carry forward with you.
