JACOBS-31410

Jacobs® Drill Chuck, High Precision/High Torque Keyless, Series: JK 130-MT4, 0.039 to 0.512 in, Ball Bearing, 3.54 in Closed Length, 3.23 in Open Length, #4 MT Mount, 1.89 in Outside Dia

• 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
