Ball Bearing Super Chucks - Jacobs Brand

The Jacobs Ball Bearing Super 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. FEATURES: * Ball bearing construction maximizes gripping force and drilling accuracy. * Jaws center-ground for absolute straightness and alignment. * Jaws specially treated to ensure extended thread life and high gripping surface hardness. * One-piece sleeve eliminates crack between driving teeth often found in other designs. * Through-hardened sleeve teeth plus hardened nose and keyholes provide outstanding wear resistance. * Fluted sleeve standard. * Each chuck 100% inspected for performance and precision.
