    Plain Bearing Keyed Chucks

    Keyless Chucks

    • Keyless chucks are self-tightening, designed so that they tighten when more torque is applied. Because the actual turning of the chuck is what tightens a keyless chuck, drills with keyless chucks can only be turned clockwise. Keyless chucks are all basically the same in design, but have different degrees of durability. They also come in stainless steel.

    Precision Keyless Chucks

    • Precision keyless chucks are designed to hold smaller drill bits in place. They are often used in high-accuracy industrial settings.

    Keyless Drill Chucks

    Keyless Drill Chucks With Integrated Shanks

    • Keyless drill chucks with integrated shanks are generally more durable because the chuck is integrated with the body of the drill. These types of chucks are usually used for industrial machines.
