Abstract

A high energy magnetizer/demagnetizer unit for a magnetizable tool bit for driving the head of a fastening device or the like comprising an elongated permanent magnet having opposed first and second poles arranged on a non-operative portion of the driving tool or the like to permit placement of a magnetizable tool bit on the elongated magnet at the first position associated with the first pole to magnetize the tool bit and also to permit placement of the tool bit at a second position associated with the second pole to demagnetize the tool bit, the second position being at a predetermined distance from the magnet. The elongated magnet defines a holding area to permit placement of at least one fastening device at a third position on the elongated magnet associated with the second pole. The fastening device is held at the third position by magnetic force at the unit is adherently attached to a driving tool and transported to a work area where the magnetized fastener and the oppositely charged tool bit are connected to the tool. Unit mounting means holds the elongated magnet and provides first and third accesses at the first and third positions, respectively, to the elongated magnet and for provides the predetermined distance at the second position. The elongated magnet is either a single elongated high energy magnet or can comprise a high energy magnet portion and an elongated shunt portion. The magnetizer/demagnetizer is either separately attached to the housing of the power tool or is unitary with the housing.
