High Torque/High Precision Keyless Chucks with Shank, Jacobs R8

High precision keyless drill chuck - arbor is integrated into the internal socket of the drill chuck
This integrated design makes it impossible for the arbor and the drill chuck to become accidentally separated, providing a unit of greater rigidity and precision
As a result of its compact design, accumulated run-out is reduced to a minimum
Self-tightening feature automatically increases gripping force proportional to increased torque to prevent tool shank slippage
Right handed operation only
100% individually controlled to ensure not to exceed a maximum total integrated run-out of 0.0016 in
