Bit Holder Repair Set
The 1/4 inch hex chuck uses a spring-tensioned sleeve to retain a detent ball against the bit shank. Fine particulate ingress (silica/concrete dust) enters the annular clearance, creating mechanical 'stiction' that prevents the sleeve from sliding to the release position. Replacing the repair set provides a fresh compression spring and sleeve with clean tolerances, overcoming the friction caused by internal contamination.
