    Jacobs Ball Bearing Chuck 18N Super Chuck

    The JACOBS Super Chuck® ball bearing chuck is specifically engineered for heavy-duty, close tolerance production drilling. It is adaptable to a wide range of production drilling equipment, jig borers, milling machines, lathes, and radials. Utilizing a ball thrust bearing to reduce friction in the chuck closing mechanism, it permits the application of more gripping force on drill shanks to maximize drilling torque under the most demanding machining conditions.
