A rechargeable battery is selectively connectable to the motor by a switch for driving a generally cylindrical cutting head. Electrical contacts in a base of a housing are engageable with a recharging base for recharging the batteries when the device is not in use. The cutting head is formed by a series of circular disks spaced along a central shaft. Thin rectangular cutting blades are circumferentially spaced about a periphery of each disk. A hemispherical zone is formed on an end portion of the cutting head by a plurality of arcuate segment blades. A generally cylindrical cap is secured over the cutting head and includes a plurality of hair receiving apertures. The cutting head is provided in different sizes for performing various different trimming operations. A specially configured plier type tool is disclosed for removing and installing the cutting heads.
