Abstract
A drive guide for driving a fastening bit includes a drive shaft, a socket shaft with a rear end non-rotationally coupled to the front end of the drive shaft and a front end with a socket that receives the fastening bit, and a sliding sleeve received over the socket shaft and slidable between a rear position and a forward position. A magnet is received in the socket with an air gap behind the magnet to magnetize a fastening bit received in the socket. An internal shoulder is integrally formed inside a rear end of the sliding sleeve. The internal shoulder abuts an external rear stop on one of the drive shaft and the socket shaft when the sliding sleeve is in the rear position and abuts a front external stop on the socket shaft when the sliding sleeve is in the forward position.
