Zusammenfassung:	A vacuum bit assembly includes an adapter having first and second ends, a central bore defined in the first end, and a locking member extending into the central bore. The vacuum bit assembly includes a drill bit having a workpiece engaging end, a connection, and a suction channel extending between the workpiece engaging and connection ends. The drill bit defines an axis of rotation that extends centrally through the drill bit between the workpiece engaging and connection ends and centrally through the adapter between the first and second ends. The drill bit includes an elongated slot adjacent the connection end. The elongated slot receives the locking member to secure the drill bit to the adapter. The vacuum bit assembly further includes a collar to selectively secure the locking member in the elongated slot. The locking member is axially movable within the elongated slot during operation of the vacuum bit assembly.
