Extra-Grip Jacobs Taper-Mount Keyless Drill Chucks
Jacobs Taper Mount
Use the included spanner wrench to tighten the chuck for up to three times the gripping torque of hand tightening. These chucks grip tighter as torque increases, which prevents tool-shank slippage and allows for precise drilling. They require an arbor (sold separately).
