  • Patent number: 11258238
    Abstract: A wire stripper operable to strip insulation from a wire, the wire stripper including a battery, a handle portion including a receptacle that receives the battery along a battery insertion axis, a motor, the motor located in the handle portion, the motor including a motor shaft that rotates about a driveline axis. The wire stripper further includes a rotary head coupled to the motor for rotation about a wire insertion axis that is perpendicular to the driveline axis. The rotary head defines a central aperture and the wire insertion axis extends through the central aperture. A blade is coupled to the rotary head for rotation with the rotary head about the wire insertion axis. The blade extends into the central aperture to cut the insulation of the wire passing through the central aperture along the wire insertion axis as the blade rotates about the wire insertion axis.
