- Features
Features |
| High precision keyless drill chuck, arbor is integrated into the internal socket of the drill chuck |
| Self-tightening feature automatically increases gripping force proportional to increased torque to prevent tool shank slippage |
| Steel chuck |
| 100% individually controlled to ensure not to exceed a maximum total integrated run-out of 0.0016 in |
| As a result of its compact design, accumulated run-out is reduced to a minimum |
| Light tightening increases the gripping torque up-to 3X over hand tightening |
| This integrated design makes it impossible for the arbor and the drill chuck to become accidently separated, providing a unit of greater rigidity and precision |
| The milled wrench flats and spanner allow for supplementary gripping torque |
| Designed for high accuracy applications on conventional or CNC equipment |
| Right hand rotation and instant spindle stop make this chuck resistant to tool loosening on high speed machines |
