Jacobs 130-R8 13 mm High Torque High Precision Keyless Chuck with R8 Shank

Engineered for maximum rigidity, this high-precision keyless chuck features an integrated arbor design to minimize run-out. The self-tightening mechanism automatically increases gripping force proportional to torque to prevent tool shank slippage.

• High-precision keyless design with an integrated arbor to ensure maximum rigidity and prevent accidental separation.
• Compact integrated design reduces accumulated run-out to a minimum for superior accuracy.
• Self-tightening feature automatically increases gripping force as torque increases to prevent tool shank slippage.
• Individually controlled to ensure a maximum total integrated run-out not exceeding 0.0016 in.
• Capacity range from 0.039 in. to 0.512 in.
• Designed for right-handed operation only.
