  • Strong Grip

    Jaws are tin coated for wear resistance and hardened to 60 HRc. With high precision ball bearing structure our drill chuck would transfer maximum torque to prevent drill slippage while minimize the lock-up occurrence during drilling operation.

  • Runout Inspection

    By mounting the assembled drill chuck into a motorized spindle to check runout while the motor is spinning to simulate the real world application, rather than manually rotating the spindle by hand wheel, we can deliver a drill chuck with confidence to satisfy your need.
