Jacobs 13 mm High Torque High Precision Keyless Drill Chuck with 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 prevent accidental separation and ensure maximum rigidity.
• 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 of no more than 0.0016 in.
• Compact design reduces accumulated run-out to a minimum for superior drilling accuracy.
• Versatile capacity ranging from a minimum of 0.039 in. to a maximum of 0.512 in.
• Designed for right-handed operation only.
