This report describes two large steel toroids used to remove beam halo for experiment 665. One toroid is 88 inch diameter and 30 feet long. The other is 120 inch diameter and 20 feet long. Both have a 7 inch diameter center hole for passage of the beam and the excitation windings. The assembled hybrid coil has water-cooled conductors in the center hole and cables on the outside. This permits the use of one piece steel plates through which the center core is inserted after assembly of the toroid steel. These toroids have advantages over conventional toroids in many aspects. The main ones being its reduced power consumption, simplicity of machining and assembly, and lower coil costs. Estimates of the induction and a simple method to buck the remnant magnetic field are included. The bucking method does not completely degauss all the toroid steel.
