Jacobs 1/2 in. Keyless Drill Chuck with 3/8-24 Mount

Engineered for precision and durability, this keyless drill chuck features a split bite jaw for increased grip and superior bit holding force. The integrated Hammerlock mechanism ensures the chuck remains secure even in high-vibration applications.

• Split bite jaw design increases grip over standard chucks by providing more contact with the bit.
• Superior gripping force converts hand-tightening torque into high mechanical advantage.
• Hammerlock mechanism provides a positive locking system to prevent loosening in high-vibration applications.
• Anti-lock nut prevents the chuck from locking in the open position.
• Precision operation meets or exceeds stringent DIN run-out and dimensional specifications.
• Rugged alloy construction maximizes durability and long-term performance.
• Ergonomic design improves comfort and performance during use.
• Capacity range: 0.062 in. to 0.500 in.
• Mounting thread: 3/8-24
