<p num="1">A quick-release bit adapter (10) includes a body (20) having first and second ends (201, 202) spaced along a longitudinal axis (C). The body (20) includes a driving hole (21) extending from the first end (201) towards the second end (202) along the longitudinal axis (C). The body (20) further includes a sliding groove (22) in communication with the driving hole (21) and intermediate the driving hole (21) and the second end (202) along the longitudinal axis (C). A through-hole (23) extends from an outer periphery of the first end (201) through the sliding groove (22). A bit (90) received in the driving hole (21) abuts and is stopped by at least one protrusion (40) extending inward from an inner periphery of the driving hole (21) towards the longitudinal axis (C). A magnetic device (30) is slideably received in the sliding groove (22) and controllable by a user through the through-hole (23) to slide along the longitudinal axis (L) between two positions to engage with or disengage from the bit (90).
