J33 Mount
Jacobs Industrial Keyless Chucks are high precision devices specifically designed for high accuracy applications on either conventional or CNC equipment. Tightened and released by hand, they permit more rapid tooling changes to increase machining productivity. A self-tightening feature produces significantly higher gripping force to resist tool shank slippage. Precision manufactured and tested to the most exacting quality standards, Jacobs Industrial Keyless Chucks can be counted on for extremely high reliability and durability under the most demanding machining conditions. FEATURES: * Each chuck precision tested and furnished with an individualized certification number identifying its specific performance characteristics. * Self-tightening feature automatically increases gripping force proportional to increased torque to prevent tool shank slippage. * All components exposed to wear are completely hardened to maintain accuracy and extend chuck life. * Jacobs taper mount permits use on a wide range of high accuracy drill presses, jig borers, milling machines and production drilling equipment.
