<p>A quick-release bit adapter (10) includes a body (20) having first and second end portions (201, 202) spaced along a longitudinal axis (C). The body (20) includes a driving hole (21) extending in the first end portion (201) along the longitudinal axis (C). The body (20) further includes a sliding chamber (22) in communication with the driving hole (21) and intermediate the driving hole (21) and the second end portion (202) along the longitudinal axis (C). A through-hole (23) extends from an outer periphery of the first end portion (201) into the sliding chamber (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 chamber (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).</p> |
