Rotary cutting pliers for cutting electric wires, having large, medium and small diameters. An electric wire is inserted into an insertion space that is open from the rotary center of a first bearing disk mounted on a first unit of the pliers so that the electric wire comes in contact with the rotary center. The wire is cut by a curved cutter in the insertion space or by a curved or circumferential cutter on a rotor embedded in the first bearing disk. A second bearing disk mounted on a second unit has a second insertion space that is inclined from the rotary center. A curved cutter in a third insertion space of the second bearing disk is open from the rotary center of a rotary disk. The rotary disk has a ratchet on the circumference that can be incorporated into the first bearing disk to complete contact with aligned supporting points at the intersection of the insertion spaces of the first and second bearing disks and with the surfaces of the curved cutters of the first and second bearing disks. The rotary disk is rotated and retained at various angles so as to allow the pliers to admit large diameter wires. The rotary disk is rotated with a feed pawl and a fixed pawl through repeated openings and closings of the handles of the first and second units to positions the rotary disk for cutting a variety of wire diameters more efficiently.
