1/2" Keyless Drill Chuck
The internal ratcheting mechanism and clamping jaws have likely reached a fatigue limit where they can no longer sustain the high-torque output of the 40V brushless motor. Axial vibrations from the hammer function can cause the sleeve to 'walk' open if the internal locking pawls are worn or fouled with construction debris. Replacing the entire chuck assembly ensures the mechanical lock is restored with fresh hardened-steel jaws and a functional friction-lock sleeve.
